Gravity Free-Air Anomaly data (ASCII format), Emperor Seamounts and Hess Rise, R/V Falkor cruise FK190726 (2019, investigators Les Watling, John R. Smith, Fabio C. Tontini)
Author(s): Watling, Les; Smith, John; Tontini, Fabio
Description: These processed free-air gravity anomaly data files were derived from raw gravity data acquired using a portable Lacoste & Romberg gravimeter with an Ultrasys control system. The data set consists of CSV line-data files of gravity anomalies at a 1 Hz sample rate and processed using POS-MV navigation. Each file contains column headers. The gravity values can be re-calculated or filtered using different techniques: A corresponding PDF document file contains the equations to re-calculate gravity. The gravity surveys were conducted at the Hess Rise and Emperor Seamounts in the North Central Pacific Ocean during R/V Falkor cruise FK190726. The cruise was primarily a biogeographic study using ROV SuBastian and the surveys were designed for ROV dive site selection and multibeam gap filling when time allowed. The data set is divided into 10 sites (places where a dedicated survey with nearly parallel lines was conducted) and 8 transits between these sites. Transits are sequentially ordered starting from Honolulu, Hawai‘i to Hess Rise and on to the Emperor Seamounts with a return transit to Honolulu along the northern side of the Northwest Hawaiian Ridge. The Emperor Seamounts surveyed include Suiko, Yomei, Godaigo, Nintoku, Jingu, Annei, and Koko (from north to south, respectively). The data files are in ASCII format and were generated as part of a project called Deep Coral Diversity at Emperor Seamount Chain 2019. Funding was provided by the Schmidt Ocean Institute (Ship, ROV, gravimeter) to Les Watling, PI, and from NOAA OER grant number NA16OAR0110192 (Science support) to John R. Smith, PI.

Ocean bottom seismometer (OBS) data on the Mid-Atlantic Ridge, acquired during the R/V Maurice Ewing survey EW9704 (1997)
Author(s): Collins, John
Description: This 1997 Ewing expedition to the Mid-Atlantic Ridge, part of the Nobel at the Mid-Atlantic Ridge Seismic Experiment, collected ocean bottom seismic refraction and single-channel seismic data. The purpose was to measure the reflected and refracted arrivals of seismic energy from sections of the mid-ocean ridge spreading center which have known, previously sampled, rock compositions. These data could then be used to identify and map rock types and test existing models for subsurface ridge structure, possibly providing a 3-dimensional map of the structure of a slow-spreading mid-ocean ridge. Funded by NSF grant OCE96-33114.

Ocean bottom seismometer data at the Blanco Transform in the Pacific Ocean, acquired during R/V Maurice Ewing expedition EW0410 (2004)
Author(s): Christeson, Gail; Nakamura, Yosio; McIntosh, Kirk
Description: The Blanco Transform Seismic cruise acquired marine seismic reflection and refraction data at the Blanco Transform in the Pacific Ocean. A companion program, EW0305, took place in 2003 where fast-spreading oceanic crust is exposed at Hess Deep. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas? Funding was provided by NSF grants OCE-0137286.

A companion program, EW0305, took place in 2003 where fast-spreading oceanic crust is exposed at Hess Deep. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas? Funding was provided by NSF grants OCE-0137286.

Ocean bottom seismometer data in the Cayman Trough, Caribbean Sea, acquired during FS Meteor expedition M115 (2015)
Author(s): Grevemeyer, Ingo; vanAvendonk, Harm; Hayman, Nick; Peirce, Christine
Description: This 2015 FS Meteor survey collected ocean bottom seismograph data in the Cayman Trough, Caribbean Sea, as part of a joint US-German-UK project. The goal was to investigate the seismic structure of the Mid-Cayman Spreading Center to determine the extent to which magmatism contributes to crustal structure of an ultra-slow oceanic rift segment. The two main ideas to be addressed were (1) Whether the MCSC hosts oceanic core complexes of exhumed crustal or mantle materials, and (2) Whether crustal thickness variations in the MCSC reflect inhibition of magmatism as the spreading-segment ends are approached. Funding for this project was obtained from the U.S. National Science Foundation under grant OCE-1356895 to UT Austin, from the German Research Foundation (DFG), and from the British Natural Environment Research Council (NERC) under grant NE/K011162/1 to Durham University. The wide-angle seismic data were recorded with instruments from UTIG and GEOMAR, as well as NERC's Ocean-Bottom Instrumentation Facility [Minshull et al., 2005]. The seismic data used in this study will be made available at the Academic Seismic Portal at UTIG (www-udc.ig. utexas.edu/sdc), the World Data Center PANGAEA (www.pangaea.de), and the British Oceanographic Data Centre (www.bodc.ac.uk).

Ocean bottom seismometer (OBS) seismic refraction data in the Gulf of Mexico, acquired by the R/V Longhorn in 1992 as part of the Gulf Probe VI project (92G06)
Author(s): Sclater, John; Maxwell, Arthur
Description: A cooperative, marine geophysical/geological and mammal bioacoustic monitoring investigation, this cruise was conducted in the western Gulf of Mexico by the University of Texas Institute for Geophysics (UTIG), Scripps Institution of Oceanography (SIO), Centro de Investigacion Cientifica y Educacion Superior de Ensenada (CICESE) of Mexico and Texas A and M University (TAMU). The purpose of seismic work was four-fold: I) to determine the velocity-depth profile of the overlying sediments and oceanic crust along the heat flow transect connecting DSDP sites 90 and 91, ii) to examine possible velocity anisotropy in the crust and upper mantle, iii) to identify the top of the ocean crust from interpretation of the normal incidence, seismic reflection pattern of the acoustic basement between Sites 90 and 91 and iv) to field test our newly upgraded, digital recording OBS instruments.The goal of this cruise was to conduct visual and acoustic observations of cetaceans in conjunction with heatflow measurements, shallow and ocean bottom seismic surveys, magnetic and gravity anomaly mapping in the western Gulf of Mexico. Funded by NSF grants OCE 9103341 and OCE 9104100.

Ocean bottom seismometer (OBS) data on the Mid-Atlantic Ridge, acquired during the R/V Maurice Ewing survey EW9704 (1997)
Author(s): Collins, John
Description: This 1997 Ewing expedition to the Mid-Atlantic Ridge, part of the Nobel at the Mid-Atlantic Ridge Seismic Experiment, collected ocean bottom seismic refraction and single-channel seismic data. The purpose was to measure the reflected and refracted arrivals of seismic energy from sections of the mid-ocean ridge spreading center which have known, previously sampled, rock compositions. These data could then be used to identify and map rock types and test existing models for subsurface ridge structure, possibly providing a 3-dimensional map of the structure of a slow-spreading mid-ocean ridge. Funded by NSF grant OCE96-33114.

Ocean bottom seismometer (OBS) data off South Island, New Zealand, acquired during R/V Maurice Ewing survey EW9601 (1996)
Author(s): Henyey, Thomas; Okaya, David; Davey, Fred; Stern, Tim
Description: This cruise was part of a joint US-New Zealand multiphase crustal-scale study of the Southern Alpine orogen across the central South Island of New Zealand, extending out to sea on either side of the island. This joint US-NZ investigation of continental deformation at convergent plate boundaries was known as the South Island GeopHysical Transection (SIGHT) project. MCS and OBS/OBH data were collected on the west (Tasman Sea) side and east (Pacific Ocean) side of South Island. At the end of the cruise OBS/OBH and SCS data were collected off Kakanui Point just south of Timaru as part of the Southern Cross Anisotropy Survey. One of the objectives was to improve understanding of continental deformation at convergent plate boundaries by using marine onshore/offshore seismic techniques to provide a detailed image of the plate boundary from both sides.

Processed 3D multichannel seismic data in the Nankai Trough accretionary prism, acquired by the R/V Maurice Ewing in 1999 (EW9907 and EW9908)
Author(s): Bangs, Nathan; Shipley, Thomas; Moore, Gregory; Morgan, Julia; Taira, Asahiko; Kuramoto, Shin'ichi
Description: The western Nankai 3-D experiment was conducted in 1999 on the R/V Maurice Ewing Legs 7 (EW9907) and 8 (EW9908). This is a collaborative project between UTIG, University of Hawaii, University of California, Santa Cruz, University of Tokyo, Japanese Geological Survey and STA JAMSTEC. The project consists of 81 dip lines ( Line numbers 92 through 172) each 80 km long with a shot spacing of 50 m. The streamer was 240 channels, 6 km long. There are also a few lines outside of the region, lines Nan-1 (the first line shot and has no navigation), 19, 20, 40, 42, and 50. Two 3-D data volumes are available, one a pre-stack time migration and the other a pre-stack depth migration. The goal of the study is to examine changes in physical properties along the thrust as it changes from aseismic to seismic expression. Understanding this transition from compaction and aseismic slip to brittle failure is a major unknown in understanding lithospheric consumption and earthquake dynamics. Funded by NSF grants OCE 9730637, OCE 9802264, and OCE 9802295.

CHIRP Data from the Mississippi River acquired during R/V Strong survey MISSRIV08 (2008)
Author(s): Magnani, M, Beatrice; McIntosh, Kirk; Waldron, Brian
Description: This 2008 cruise on the M/V Strong, a collaborative effort between the University of Memphis and University of Texas at Austin, collected high-resolution seismic reflection data and CHIRP data along the Mississippi River, from Helena, Arkansas, to Caruthersville, Missouri. It was followed by two more field seasons in 2010 and 2011. It has been proposed that the seismicity in the New Madrid seismic zone is either 1) episodic; 2) very young (at least in its present incarnation); or 3) migrates throughout a broad region at the continental or regional scale. The purpose of the seismic acquisition was to illuminate the shallow section and provide images of the Mississippi river sediments and of the suspected faults concealed under the subdued topography, providing detailed information on the partitioning of the deformation among key structures beyond the limit of the New Madrid seismic zone that would enable the PIs to test the various hypotheses concerning the zone. Funded by NSF grant 0738855.

CHIRP Data from the eastern Mississippi Sound, Alabama, acquired during R/V Jenny survey JN0406 (2004)
Author(s): Anderson, John
Description: Party of a study to explore incised valley fill from three Gulf of Mexico bays, specifically Mobile Bay, Galveston Bay, and Corpus Christi Bay, this R/V Jenny survey collected high-resolution CHIRP data in eastern Mississippi Sound, Alabama during the summer of 2004. Two companion cruises, JN0206 and JN0306, collected CHIRP data in eastern Mississippi Sound in the summers of 2002 and 2003. The goal was to use the data to identify flooding surfaces and help quantify coastal response to forcing mechanisms. This will help test the hypothesis that variations in the rate of coastal subsidence and river discharge were not the cause of the observed coastal backstepping events. Funded by NSF grant EAR-0107650, the American Chemical Society Petroleum Research Fund grant ACS-PRF 36694-G8, the Gulf Coast Association of Geological Societies, and the Hooks Research Fund.

Ocean bottom seismometer (OBS) data across the Caribbean-northeastern South America arc-continent collision zone, acquired during the R/V Maurice Ewing survey EW0404 (2004)
Author(s): Christeson, Gail; Pecher, Ingo; Mann, Paul; Levander, Alan; Ave, Lallemant, Hans; Sawyer, Dale; Lenardic, Adrian; Zelt, Colin
Description: Three teams were involved in the active-source seismic field program: 1) A science party aboard the R/V Maurice Ewing (co-chief scientists P. Mann and D. Sawyer) acquired approximately 6000 km of seismic reflection data. 2) A science party aboard the R/V Seward Johnson II (chief scientist G. Christeson, cruise report) deployed and recovered ocean bottom seismometers (OBSs) along 5 transects; the Ewing provided the seismic source for these instruments. 3) A science party in Venezuela and the ABC islands deployed and recovered seismographs along 4 transects and the island arc; the Ewing and 8 land shots provided the seismic source for these instruments. The purpose was to carry out a geologic-geophysical investigation to test hypotheses related to arc-continent collision and accretion, HP/LT rock exhumation and development of folded belts.

Ocean bottom seismometer data at Hess Deep, acquired during R/V Maurice Ewing expedition EW0305 (2003)
Author(s): Christeson, Gail; Nakamura, Yosio; McIntosh, Kirk
Description: This cruise acquired 16 scarp-parallel MCS profiles and 7 scarp-perpendicular MCS profiles as well as OBS data across the Hess Deep, near the Pacific-Cocos-Nazca triple junction, eastern Pacific Ocean. A companion program, EW0410, took place in October-November 2004 along the Blanco Transform Fault. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas? Funding was provided by NSF grants OCE-0137286.

Ocean bottom seismometer data in the Cayman Trough, Caribbean Sea, acquired during FS Meteor expedition M115 (2015)
Author(s): Grevemeyer, Ingo; vanAvendonk, Harm; Hayman, Nick; Peirce, Christine
Description: This 2015 FS Meteor survey collected ocean bottom seismograph data in the Cayman Trough, Caribbean Sea, as part of a joint US-German-UK project. The goal was to investigate the seismic structure of the Mid-Cayman Spreading Center to determine the extent to which magmatism contributes to crustal structure of an ultra-slow oceanic rift segment. The two main ideas to be addressed were (1) Whether the MCSC hosts oceanic core complexes of exhumed crustal or mantle materials, and (2) Whether crustal thickness variations in the MCSC reflect inhibition of magmatism as the spreading-segment ends are approached. Funding for this project was obtained from the U.S. National Science Foundation under grant OCE-1356895 to UT Austin, from the German Research Foundation (DFG), and from the British Natural Environment Research Council (NERC) under grant NE/K011162/1 to Durham University. The wide-angle seismic data were recorded with instruments from UTIG and GEOMAR, as well as NERC's Ocean-Bottom Instrumentation Facility [Minshull et al., 2005]. The seismic data used in this study will be made available at the Academic Seismic Portal at UTIG (www-udc.ig. utexas.edu/sdc), the World Data Center PANGAEA (www.pangaea.de), and the British Oceanographic Data Centre (www.bodc.ac.uk).

Processed multi-channel seismic profile images (PNG format) for 0-75 Ma equatorial Atlantic ocean floor acquired in 2015 as part of the TransAtlanticILAB project
Author(s): Singh, Satish; Audhkhasi, Pranav
Description: These processed MCS image files are part of a seismic investigation of seafloor, basement and layer 2A for the African plate in the equatorial Atlantic ocean from 0-75 Ma (investigator Satish Singh). The data is cited in Audhkhasi and Singh (2019). The multi-channel seismic data was acquired in individual sequences starting from sequence 1 (eastern most) to sequence 14 (western most) using a 12 km long streamer. Three ridge-orthogonal profiles were acquired, each composed of more than one sequence. The three ridge-orthogonal parts of the profiles have been combined to produce a continuous flow line from 0-75 Ma. Processed data files (SEG-Y format) and their associated images (PNG format) have been made available for the sequences 1, 4, 5, 6, 7, 9, 10, 11, 14. The omitted sequences are either entirely in the turning part of the profile (for instance, sequence 12) or are too small (< 10 km) to provide any substantial information (for instance, sequence 3). The processing steps involve geometry merging, velocity analysis for layer 2A triplication, and top and bottom mute to stack only 2A retrograde energy for super-CMP gathers. These steps are described in supplementary figure S2 of Audhkhasi and Singh (2019). The seafloor, basement and 2A event was picked on the processed data and has been made available as a related data set for three ridge-orthogonal parts of the profile: leg1_age_sf_l2a.mat, leg2_age_sf_bs_l2a.mat and leg3_age_sf_bs_l2a.mat. The picks were used for plotting figure 4 of Audhkhasi and Singh (2019).

Reprocessed 4-channel seismic data offshore the Nicoya Peninsula, Costa Rica margin, acquired in 2002 during the R/V Melville survey VANC02MV
Author(s): Harris, Robert; Stein, Carol; Wheat, Geoffrey; Wang, Kelin
Description: This 2002 Melville cruise, which collected 4-channel MCS data, was part of a multidisciplinary investigation of the thermal state of the subducting lithosphere offshore of the Costa Rica margin. Funded by the U.S. NSF (grants OCE00-01892, OCE00-01941, and OCE00-02031). Its companion cruise, Ticoflux I, was on board the R/V Ewing in 2001. The goals were to determine the comparative thermal state of the subducting lithosphere in these regions, the associated heat and fluid fluxes responsible for the subducting slab thermal states, and how these variables affect subduction zone processes, including chemical flux rates. The data were later reprocessed by Jared Kluesner such that the shot spacing and the CDP (or CMP) spacing (half of channel spacing) is forced to be the same (~30 m), resulting in 4 fold data (4 traces per CDP gather).

Single-channel seismic field data in the Gulf of Mexico, acquired by the R/V Longhorn in 1992 as part of the Gulf Probe VI project (92G06)
Author(s): Sclater, John; Maxwell, Arthur
Description: A cooperative, marine geophysical/geological and mammal bioacoustic monitoring investigation, this cruise was conducted in the western Gulf of Mexico by the University of Texas Institute for Geophysics (UTIG), Scripps Institution of Oceanography (SIO), Centro de Investigacion Cientifica y Educacion Superior de Ensenada (CICESE) of Mexico and Texas A and M University (TAMU). The purpose of seismic work was four-fold: I) to determine the velocity-depth profile of the overlying sediments and oceanic crust along the heat flow transect connecting DSDP sites 90 and 91, ii) to examine possible velocity anisotropy in the crust and upper mantle, iii) to identify the top of the ocean crust from interpretation of the normal incidence, seismic reflection pattern of the acoustic basement between Sites 90 and 91 and iv) to field test our newly upgraded, digital recording OBS instruments.The goal of this cruise was to conduct visual and acoustic observations of cetaceans in conjunction with heatflow measurements, shallow and ocean bottom seismic surveys, magnetic and gravity anomaly mapping in the western Gulf of Mexico. Funded by NSF grants OCE 9103341 and OCE 9104100.

Reprocessed 4-channel seismic data offshore the Nicoya Peninsula, Costa Rica margin, acquired in 2002 during the R/V Melville survey VANC02MV
Author(s): Harris, Robert; Stein, Carol; Wheat, Geoffrey; Wang, Kelin
Description: This 2002 Melville cruise, which collected 4-channel MCS data, was part of a multidisciplinary investigation of the thermal state of the subducting lithosphere offshore of the Costa Rica margin. Funded by the U.S. NSF (grants OCE00-01892, OCE00-01941, and OCE00-02031). Its companion cruise, Ticoflux I, was on board the R/V Ewing in 2001. The goals were to determine the comparative thermal state of the subducting lithosphere in these regions, the associated heat and fluid fluxes responsible for the subducting slab thermal states, and how these variables affect subduction zone processes, including chemical flux rates. The data were later reprocessed by Jared Kluesner such that the shot spacing and the CDP (or CMP) spacing (half of channel spacing) is forced to be the same (~30 m), resulting in 4 fold data (4 traces per CDP gather). See vanc02mv.README.Kluesner for details.

Description: Part of the SONGS project, this 2013 R/V New Horizon expedition conducted a 2D shallow seismic survey, collecting both sparker and boomer data, in the vicinity of the San Onofre Nuclear Generating Station (SONGS), offshore California. The objectives included imaging the fault geometry in the seismogenic zone and determining the recurrence interval for the fault systems. These data were processed for velocity by Geotrace and were used for processing the multi-channel seismic data (source sparker). UTM navigation is in the headers of the original SEG-Y files. Funding was from Southern California Edison. DOI: 10.1594/IEDA/500042

Processed Multi-Channel Seismic Data from the Mississippi River acquired during R/V Strong survey MISSRIV08 (2008)
Author(s): Magnani, M, Beatrice; McIntosh, Kirk; Waldron, Brian
Description: This 2008 cruise on the M/V Strong, a collaborative effort between the University of Memphis and University of Texas at Austin, collected high-resolution seismic reflection data and CHIRP data along the Mississippi River, from Helena, Arkansas, to Caruthersville, Missouri. It was followed by two more field seasons in 2010 and 2011. It has been proposed that the seismicity in the New Madrid seismic zone is either 1) episodic; 2) very young (at least in its present incarnation); or 3) migrates throughout a broad region at the continental or regional scale. The purpose of the seismic acquisition was to illuminate the shallow section and provide images of the Mississippi river sediments and of the suspected faults concealed under the subdued topography, providing detailed information on the partitioning of the deformation among key structures beyond the limit of the New Madrid seismic zone that would enable the PIs to test the various hypotheses concerning the zone. Funded by NSF grant 0738855.

Processed multi-channel seismic data from the Cascadia Subduction Zone acquired during the R/V Marcus G. Langseth expedition MGL1212 (2012)
Author(s): Holbrook, W., Steven; Kent, Graham; Keranen, Kathleen; Johnson, H.Paul; Trehu, Anne
Description: Part of the COAST (Cascadia Open-Access Seismic Transects) project, this 2012 R/V Langseth cruise served as an open-access, open-participation 2D seismic survey of the Cascadia subduction margin off Grays Harbor, Washington, USA, collecting data that will provide background information for siting and planning any future 3D work on this part of the margin. The objectives were to image the plate boundary, to identify downdip variations in the character of subduction thrust associated with seismic rupture, to characterize the subduction interface, and to quantify pore fluid pressure, fluid budgets, and upstream inputs to the ETS zone. Funded by NSF grants OCE-1150628, 1153563, 1147762, 1147841, and 1149095. DOI: 10.1594/IEDA/500038

Processed multichannel seismic data off Taiwan, acquired during R/V Marcus G. Langseth expedition MGL0908 (2009) as part of the Taiwan Integrated GEodyamics Research project (TAIGER)
Author(s): McIntosh, Kirk; Nakamura, Yosio; vanAvendonk, Harm; Lavier, Luc; Liu, Char-Shine; Hsu, Shu-Kun; Lee, Chao-Shing
Description: This was the fourth of four expeditions that surveyed the northern Philippine Sea and the area around Taiwan in support of the TAIGER project, a collaborative project between U.S. and Taiwanese scientists. Legs MGL0905, MGL0906, and MGL0908 used the seismic source array on the R/V Langseth to acquire deep-penetration seismic reflection data and to provide seismic source signals to be recorded by ocean bottom seismographs (OBSs) and seismic instruments on land in Taiwan. The OBSs which recorded the seismic signals during these legs were deployed by various Taiwanese ships and operated by Taiwanese groups and an OBS group from Scripps Institution of Oceanography (the U.S. OBS pool). Leg MGL0907 was dedicated to recovering broadband OBSs, previously deployed in May 2008 (cruise MGLN-38MV of the R/V Melville). Its main goals were to acquire OBS data along the primary TAIGER transects T1 and T2 south of Taiwan and to acquire MCS, OBS, and potential field data across the poorly-surveyed northwestern portion of the Philippine Sea tectonic plate. 91 OBS stations were deployed during this cruise.

Processed Multi-Channel Seismic Data off South Island, New Zealand, acquired during R/V Maurice Ewing survey EW9601 (1996)
Author(s): Henyey, Thomas; Okaya, David; Davey, Fred; Stern, Tim
Description: This cruise was part of a joint US-New Zealand multiphase crustal-scale study of the Southern Alpine orogen across the central South Island of New Zealand, extending out to sea on either side of the island. This joint US-NZ investigation of continental deformation at convergent plate boundaries was known as the South Island GeopHysical Transection (SIGHT) project. MCS and OBS/OBH data were collected on the west (Tasman Sea) side and east (Pacific Ocean) side of South Island. At the end of the cruise OBS/OBH and SCS data were collected off Kakanui Point just south of Timaru as part of the Southern Cross Anisotropy Survey. One of the objectives was to improve understanding of continental deformation at convergent plate boundaries by using marine onshore/offshore seismic techniques to provide a detailed image of the plate boundary from both sides.

Processed multichannel seismic data in the Sandino forearc basin, offshore Costa Rica, Nicaragua, Honduras and El Salvador, acquired during R/V Maurice Ewing expedition EW0412 (2004)
Author(s): Fulthorpe, Craig; McIntosh, Kirk
Description: The EW0412 expedition was part of NicStrat, a project designed to image Neogene depositional sequences indicative of sea-level change and stratal geometries that may reflect local tectonic history. The primary objectives were 1) to test the hypothesis that the stratigraphic records of eustatic and tectonic processes can be identified and distinguished on high-resolution MCS data from the Sandino forearc basin, on the Pacific margin of Nicaragua; and 2) to evaluate the record of tectonic events in the form of local unconformities and/or tectonically controlled variations in the geometries and stacking patterns of regional eustatic sequences. Funding was provided by NSF grant OCE-0241179. DOI: 10.1594/IEDA/500006

Processed multichannel seismic data in the Solomon Islands convergent zone, Southwest Pacific Ocean, acquired during the R/V Maurice Ewing survey EW9511 (1995)
Author(s): Mann, Paul; Coffin, Millard; Shipley, Thomas
Description: A U.S.-Japan cooperative program to map crustal and perhaps upper mantle structures in the Solomon Islands convergent zone. Due to a major cable loss on the previous cruise the cable configuration varied between 112 and 128 channels as new sections were repaired or on-loaded (see cruise report). Japanese OBS's were used in this experiment along line SI-1. The primary objective of the MCS study and an independently proposed OBS study by Drs. K. Suyehiro and colleagues at the Ocean Research Institute in Tokyo, Japan, is to test two models for the formation of the Malaita anticlinorium - the deformed wedge of Cretaceous-Cenozoic pelagic limestone, basalt, and clastic rocks that most previous workers agree to be an emergent part of the Ontong Java Plateau. One model predicts tectonic wedging of the Solomon island arc beneath the Ontong Java plateau. A second, alternative model predicts a more familiar oceanic accretionary wedge geometry with northeastward (plateauward) offscraping and thrust imbrication of plateau rocks. Our proposed MCS-OBS study focusing on the Malaita anticlinorium and North Solomon trench will use state-of-the-art data acquisition and processing techniques to address fundamental questions concerning the subduction/accretion/fragmentation of oceanic plateaus at subduction zones and their deformational effects on the overriding island arc-including collision-related arc polarity reversal. Answers to these questions are important for understanding how oceanic plateaus may contribute to growth of continents through time and how subduction zones initiate by polarity reversal. Funded by NSF grant OCE9301608.

Processed multichannel seismic data in the Woodlark Basin, acquired during the R/V Maurice Ewing survey EW9510 (1995)
Author(s): Taylor, Brian; Martinez, Fernando; Hey, Richard
Description: This was an ODP site survey (prior to leg 180) to characterize the rift-to-spreading transition in the Woodlark Basin. The purpose was to study the structural and volcanic processes and the dynamics of the upper mantle that are associated with the splitting of continents. The lateral variation from continental rifting to seafloor spreading within the Woodlark Basin makes it an ideal area to investigate the active process of rifting and spreading center propagation into a continent. The results of this study will provide necessary site survey data with which to plan drilling in the Woodlark Basin. Funded by NSF grant OCE92-01691.

Processed multichannel seismic data along the East Pacific Rise south of Garrett Fracture Zone, acquired during the R/V Maurice Ewing survey EW9102 (1991)
Author(s): Mutter, John; Buhl, Peter; Orcutt, John; Harding, Alistair
Description: This Two-ship Experiment on a Ridge Axis (TERA) provided the first detailed geophysical constraints on the crustal structure along the East Pacific Rise south of the Garrett fracture zone, a major focus of the RIDGE initiative. The R/V Maurice Ewing< and Thomas Washington (TERA01WT) were to collect three types of data: (1) 20 closely-space, single-ship multichannel seismic reflection profiles along the EPR; (2) 25 two-ship expanding spread profiles along and parallel to the rise axis in this same area; and (3) a 700-km-long multichanel seismic reflection profile along the EPR from the Garrett fracture zone to the large overlapping spreading center at 20.5S. The objectives were to use these data to test the spreading rate dependence of magma chamber size; to examine the relationship between crustal magma chambers and along-axis changes in morphology, segmentation and basalt geochemistry; and to resolve better how the first-order seismic structure of oceanic crust, including Moho and seismic layer 3, developed during the first few hundred thousand years after crustal formation. Funded by NSF grants OCE90-12707, OCE90-12781, OCE90-12596, and OCE91-02899.

Processed multichannel seismic data across the in the Bransfield Strait and Shetland Trench, northern Antarctic Peninsula, acquired during the R/V Maurice Ewing survey EW9101 (1991)
Author(s): Hayes, Dennis; Mutter, John; Dalziel, Ian
Description: This was a joint UT and Lamont-Doherty Earth Observatory program collecting a series of MCS lines in the Bransfield Strait, across the South Shetland Trench and farther south along the Antarctic margin. UTIG was responsible for the Bransfield Strait and South Shetland Trench data. Additional lines collected farther south along the margin were the responsibility of Lamont-Doherty Earth Observatory. The goals were to increase understanding of the following processes: Andean-type orogenesis, continental lithosphere extension in a convergent continental margin setting, ridge crest subduction, and interaction of large- offset fracture zones with convergent margins, including the uplift of subduction complexes. Funded by NSF grants OCE89-17332 and OCE89-16436.

Processed multichannel seismic data across the Chicxulub impact structure on the Yucatan Peninsula, Mexico, acquired during the R/V Maurice Ewing survey EW0501 (2005)
Author(s): Gulick, Sean; Christeson, Gail; Barton, Penny; Morgan, Joanna; Warner, Mike; Urrutia-Fucugauchi, Jamie
Description: This combined reflection-refraction seismic experiment was a joint project between UTIG, University of Arizona, Imperial College (UK), Cambridge University (UK), UNAM (Mexico), and CICY (Mexico). The goals were: 1) to determine the direction of approach and angle of the Chicxulub impact as modeling has shown that a 15-20 time greater amount of airborne particles are produced by low-angle impacts; 2) to map the deformation (faults and broken rock) recorded in the upper crust near the crater center that may explain the way the surface of the Earth is damaged by large meteor or comet impacts; 3) to image the key features in the northwest portion of the crater to enable better understanding of the Chicxulub impact structure and prepare for possible future sampling to examine the melted and shattered rocks deep within the crater; 4) to model the 3-D collapse of the crater to examine both the deformation and the environmental effects of the impact to better understand how such an impact can cause worldwide mass extinctions.

Processed multichannel seismic data in the Sandino forearc basin, offshore Costa Rica, Nicaragua, Honduras and El Salvador, acquired during R/V Maurice Ewing expedition EW0412 (2004)
Author(s): Fulthorpe, Craig; McIntosh, Kirk
Description: The EW0412 expedition was part of NicStrat, a project designed to image Neogene depositional sequences indicative of sea-level change and stratal geometries that may reflect local tectonic history. The primary objectives were 1) to test the hypothesis that the stratigraphic records of eustatic and tectonic processes can be identified and distinguished on high-resolution MCS data from the Sandino forearc basin, on the Pacific margin of Nicaragua; and 2) to evaluate the record of tectonic events in the form of local unconformities and/or tectonically controlled variations in the geometries and stacking patterns of regional eustatic sequences. Funding was provided by NSF grant OCE-0241179.

Processed multichannel seismic data across the Caribbean-northeastern South America arc-continent collision zone, acquired during the R/V Maurice Ewing survey EW0404 (2004)
Author(s): Christeson, Gail; Pecher, Ingo; Mann, Paul; Levander, Alan; Ave, Lallemant, Hans; Sawyer, Dale; Lenardic, Adrian; Zelt, Colin
Description: Three teams were involved in the active-source seismic field program: 1) A science party aboard the R/V Maurice Ewing (co-chief scientists P. Mann and D. Sawyer) acquired approximately 6000 km of seismic reflection data. 2) A science party aboard the R/V Seward Johnson II (chief scientist G. Christeson, cruise report) deployed and recovered ocean bottom seismometers (OBSs) along 5 transects; the Ewing provided the seismic source for these instruments. 3) A science party in Venezuela and the ABC islands deployed and recovered seismographs along 4 transects and the island arc; the Ewing and 8 land shots provided the seismic source for these instruments. The purpose was to carry out a geologic-geophysical investigation to test hypotheses related to arc-continent collision and accretion, HP/LT rock exhumation and development of folded belts.

Processed multichannel seismic data at Hess Deep, acquired during R/V Maurice Ewing expedition EW0305 (2000)
Author(s): Christeson, Gail; Nakamura, Yosio; McIntosh, Kirk
Description: This cruise acquired 16 scarp-parallel MCS profiles and 7 scarp-perpendicular MCS profiles as well as OBS data across the Hess Deep, near the Pacific-Cocos-Nazca triple junction, eastern Pacific Ocean. A companion program, EW0410, took place in October-November 2004 along the Blanco Transform Fault. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas?Funding was provided by NSF grants OCE-0137286.

Processed multichannel seismic data (brute stacks) in the Gulf of California, acquired during the R/V Maurice Ewing survey EW0210 (2002)
Author(s): Lizarralde, Daniel; Axen, Gary; Kent, Graham; Fletcher, John; Gonzalez-Fernandez, Antonio; Harding, Alistair; Holbrook, W., Steven; Umhoefer, Paul
Description: Funded through NSF MARGINS, this Gulf of California experiment (PESCADOR: Premiere Experiment, Sea of Cortez, Addressing the Development of Oblique Rifting) involved two ships, the R/V Maurice Ewing and the R/V New Horizon. The Ewing provided the acoustic source and acquired multi-channel seismic data, and the New Horizon tended to 206 deployments of ocean bottom seismometers. The purpose was to delineate the geometries and patterns of crustal extension and rift magmatism along three main conjugate margins across Alarcon, Guaymas and Delfin Basins (to study the south to north seafloor-spreading to non-spreading mode) and a E-W profile along Wagner Basin (to study the low-angle detachment fault at depth). The questions to be addressed included strain partitioning, volumetric and emplacement style of rift magmatism, along-axis differences in extension style and the influence of sedimentation on deformation. This data set consists of real-time stacks made at sea. Funded by NSF grants OCE01-11983, OCE01-12149, OCE01-12058, OCE01-12152, and OCe01-11738.

Processed multichannel seismic data across the Mariana island-arc system, acquired during the R/V Maurice Ewing survey EW0203 (2002)
Author(s): Klemperer, Simon; Taylor, Brian; Fryer, Patricia; Moore, Gregory; Goodliffe, Andrew; Hildebrand, John
Description: The MARGINS programs in the US and Japan (of NSF and MEXT) funded an integrated seismic study (marine multi-channel seismic reflection, controlled-source wideangle reflection/refraction, and passive recording of local and teleseismic earthquakes) to provide a comprehensive velocity, attenuation, structural and stratigraphic image of the Mariana island-arc system, from the subducting Pacific Plate to the backarc, at 14-20N, 141-149E. The study included two cruises, EW0202 and EW0203. This cruise, EW0203, served as part 2 of the study, deploying Ocean Bottom Seismographs (OBSs) and shooting MCS lines over them. Its companion cruise, EW0202, concentrated on MCS profiling. The principal objectives of the study were to understand: 1) velocity and attenuation structure of the mantle, 2) large-scale flow of the mantle wedge, 3) velocity structure of the subducting oceanic crust, 4) seismic stratigraphy and structure of the forearc, arc and remnant arc, 5) the magma chamber below the volcanoes, 6) a possible double seismic zone, and 7) updip an downdip limits of the seismogenic zone. Funded by NSF grants OCE00-01798, OCE00-01956, OCE00-01938, OCE00-02878.

Processed multichannel seismic data off the Exmouth and Cuvier margin, northwestern Australia, acquired during the R/V Maurice Ewing survey EW0113 (2001)
Author(s): Driscoll, Neal; tenBrink, Uri; Diebold, John; Karner, Garry; Taylor, Brian
Description: The Exmouth and Cuvier margin system represents one of the best locales to study the differences between wide versus narrow rifts and to define the interplay between strain partitioning, volcanism, segmentation, and the continent-ocean transition. This geophysical investigation of the Exmouth and Cuvier margins was designed to test alternate models for continental margin development, and when these results are integrated with those from other margin studies, will lead to a better overall understanding and appreciation of: the strain partitioning across margins between the brittle upper crust and the ductile lower crust and lithospheric mantle (e.g., the upper plate paradox); the interplay between extensional style (rift architecture), magmatism and detachments; the continent-ocean transition, and the origin of magnetic anomalies observed off the Exmouth and Cuvier margin; the formation of seaward-dipping reflectors along the continent-ocean boundaries and the importance of faults in their formation. Funded by NSF grants OCE99-11877, OCE99-12007, OCE99-11962.

Processed multichannel seismic data along the Mid-Atlantic Ridge, acquired during the R/V Maurice Ewing survey EW0102 (2001)
Author(s): Tucholke, Brian; Collins, John
Description: This MCS cruise surveyed three well-developed smoothly-domed, turtleback shaped exposures (termed megamullions) of deep-crustal plutonic and upper-mantle ultramafic rock that occur on the flanks of the Mid-Atlantic Ridge. The objectives were to establish the upper seismic velocity structure of these megamullions both laterally and vertically, to gain insight into the deep nature of the oceanic crust and upper mantle now exposed in these megamullions, and to gain a better understanding of how and why megamullions form. This survey was to serve as a foundational site survey to Ocean Drilling Program (ODP) proposals 512-Full and 532-Full and addresses several crustal objectives of the ODP Long Range Plan. Funded by NSF grant OCE99-87004.

Processed multichannel seismic data, including SCREECH Transact 1, crossing the Newfoundland margin, acquired during the R/V Maurice Ewing survey EW0007 2000)
Author(s): Holbrook, W., Steven; Tucholke, Brian; Louden, Keith; Larsen, Hans, Christian; Deemer, Sharon; Hurich, Charles; Hall, Jeremy
Description: This data set consists of SCREECH Transect 1 (1MCS) and lines 101, 102, and 103. This ODP site survey on the Newfoundland margin was a joint project, SCREECH (Studies of Continental Rifting and Extension on the Eastern Canadian SHelf), between the University of Wyoming, WHOI, Dalhousie University, and Danish Lithosphere Centre scientists. The Ewing acquired MCS, magnetic, gravity, and multibeam bathymetric data while the Oceanus acquired wide-angle reflection/refraction data via ocean-bottom seismometers/hydrophones (OBS/Hs). This cruise was to provide a critical dataset for testing models of continental rifting, breakup, and initiation of seafloor spreading in a non-volcanic rifted environment. Its objectives were to: 1) characterize the nature of the crust transitional between oceanic and continental crust in the region; 2) provide a comparison with the Iberian margin, thereby allowing testing of models of pure-shear vs. simple-shear during rifting; and 3) determine the amount of igneous material intruded and extruded during rifting, providing comparative data with other volcanic rifted margins, such as the East Greenland margin. Funding was provided by NSF (grants OCE98-19599 and OCE98-19053), Dalhousie University, Geological Survey of Denmark and Greenland, Danish National Research Foundation (Danmarks Grundforskningsfond), and the Natural Sciences and Engineering Council of Canada.

Gridded bathymetry data (ESRI ASCII format) for the Discovery Transform Fault and possible nano-plate
Author(s): McGuire, Jeffrey; Wolfson-Schwehr, Monica
Description: This multibeam gridded bathymetry data set was collected using an EM300 swath sonar system during R/V Thomas Thompson cruise TN214. The primary goal of the cruise was to deploy 40 ocean bottom seismometers (OBS) and 7 seafloor geodesy tripods at the Quebrada/Discovery/Gofar (QDG) transform fault system on the equatorial East Pacific Rise. There were three target survey areas for high-resolution seafloor mapping: the Discovery and Quebrada transform faults, and a potentially rotating nano-plate just north of the Discovery transform fault. The surveys were typically carried out at a survey speed of 5 knots, with a fixed swath width of 4 km (135 beams/ping). The bathymetry was processed using the CARIS Hips&Sips software. The data file is in ESRI ASCII grid format, gridded at a resolution of 75m with no interpolation to fill data gaps, WGS-84, UTM zone 13S. The gridded TN214 bathymetry data is used in the Wolfson-Schwehr et al., 2014 paper. This project was funded by NSF Award 0242117, with Principal Investigators Jeffery McGuire, John Collins, and Robert Detrick. DOI: 10.1594/IEDA/324929

Processed multichannel seismic data in the Solomon Islands convergent zone, Southwest Pacific Ocean, acquired during the R/V Maurice Ewing survey EW9511 (1995)
Author(s): Mann, Paul; Coffin, Millard; Shipley, Thomas
Description: A U.S.-Japan cooperative program to map crustal and perhaps upper mantle structures in the Solomon Islands convergent zone. Due to a major cable loss on the previous cruise the cable configuration varied between 112 and 128 channels as new sections were repaired or on-loaded (see cruise report). Japanese OBS's were used in this experiment along line SI-1. The primary objective of the MCS study and an independently proposed OBS study by Drs. K. Suyehiro and colleagues at the Ocean Research Institute in Tokyo, Japan, is to test two models for the formation of the Malaita anticlinorium - the deformed wedge of Cretaceous-Cenozoic pelagic limestone, basalt, and clastic rocks that most previous workers agree to be an emergent part of the Ontong Java Plateau. One model predicts tectonic wedging of the Solomon island arc beneath the Ontong Java plateau. A second, alternative model predicts a more familiar oceanic accretionary wedge geometry with northeastward (plateauward) offscraping and thrust imbrication of plateau rocks. Our proposed MCS-OBS study focusing on the Malaita anticlinorium and North Solomon trench will use state-of-the-art data acquisition and processing techniques to address fundamental questions concerning the subduction/accretion/fragmentation of oceanic plateaus at subduction zones and their deformational effects on the overriding island arc-including collision-related arc polarity reversal. Answers to these questions are important for understanding how oceanic plateaus may contribute to growth of continents through time and how subduction zones initiate by polarity reversal. Funded by NSF grant OCE9301608.

Author(s): Piret, Loic; Troch, Matthias; Vandekerkhove, Elke; Harada, Naomi; Moffat, Carlos; Rivera, Andres; Mansilla, Rodrigo; Bertrand, Sebastien
Description: Second version of a bathymetric map of the Baker-Martinez fjord complex (Chile, 48°S) constructed from multiple data sets: multibeam echosounder data of Baker channel (Harada et al., 2008) and of Steffen fjord and Baker river delta (Vandekerkhove et al.), single beam echosounder data of Martinez channel (R/V Sur-Austral 2015/2016) and Jorge Montt fjord (Rivera et al., 2012, Moffat, 2014 and additional data from C. Moffat) and individual bathymetry points (digitized using Global Mapper software) from two SHOA nautical charts (SHOA, 2001, 2008). The heterogeneous data with distinct spatial resolution was gridded using the kriging method (3.6 arc-second resolution) in Surfer from Golden Software. Compared to the first version (Piret et al., 2017), this new version features improved bathymetry for the Martinez Channel. We intend to update this map when new data sets become available. The data file is in a netCDF grid format that is compatible with Ocean Data View (ODV) software. Geographic (unprojected lat/lon) Coordinate System – World Geodetic System 1984 (WGS84).

Author(s): Nyalugwe, Victor; Abdelsalam, Mohamed; Atekwana, Estella; Katumwehe, Andrew; Mickus, Kevin; Salima, Jalf; Njinju, Emmanuel; Emishaw, Luelseged
Description: This Total Magnetic Intensity (TMI) data set covers the region of southern Malawi between longitudes 34 45 E – 36 00 E and latitudes 14 45 S and 16 15 S. This processed data set is part of aeromagnetic data acquired in 2013 by the Government of Malawi through the Ministry of Mines – Geological Survey Department. The data set was collected with NE-SW oriented flight lines, flight line spacing of 250 m, tie lines spacing of 2.5 km, and an average terrain clearance of 60 m. The data were reduced to pole (RTP); hence the gridded data archived in this data portal is RTP TMI. The data is used in a study of the lithospheric structure beneath the Cretaceous Chilwa Alkaline Province (CAP) in southern Malawi and northeastern Mozambique. The data set is made available to other geoscientists for the purpose of scientific research only. Full acknowledgement should be given to the Government of Malawi – Ministry of Mines – Geological Survey Department. For addition specification of data acquisition contact the Geological Survey Department at P.O. Box 27, Zomba, Malawi. DOI: 10.1594/IEDA/324860

Uppermost mantle P-wave seismic velocity structure of the Juan de Fuca and Gorda plates (VanderBeek and Toomey, 2019)
Author(s): VanderBeek, Brandon; Toomey, Douglas
Description: This data set is a tomographic model of mantle P-wave speeds beneath the Juan de Fuca and Gorda plates offshore of the Pacific northwest. The model conforms to a surface located 1 km beneath the oceanic Moho. Due to the nature of the seismic data used to construct this tomographic image (primarily Pn head waves), P-wave speeds reflect an average over the uppermost ~7 km of the oceanic mantle. The model and results are described in VanderBeek and Toomey (2019). In summary, the model was constructed by inverting 3363 travel-times from 162 local earthquakes recorded by Cascadia Initiative ocean bottom seismometers. Travel-times were inverted using an iterative anisotropic tomography algorithm. The isotropic and anisotropic component of the model is provided as an ASCII file (see header comments in file for file structure). The isotropic component of the model (the P-wave speed) is also provided as a data layer in GeoMapApp. The data set was generated as part of the projects called "Structure and Dynamics of the Lithosphere-Asthenosphere System Beneath the Juan de Fuca Plate" and "Understanding Subduction Systems by Linking Anisotropic Seismic Imaging and Geodynamic Modeling". This work was supported by the National Science Foundation under grants OCE‐1139701, OCE‐1333196, and EAR‐1520694 to the University of Oregon. DOI: 10.1594/IEDA/324858

Crustal and topmost mantle velocity structure of the Endeavour segment, Juan de Fuca Ridge (Arnoux et al., 2019)
Author(s): Arnoux, Gillean; Toomey, Douglas; Hooft, Emilie; Wilcock, William
Description: This data set consists of a tomographic model of the anisotropic P-wave seismic velocity structure of the crust and topmost mantle beneath the seafloor at the Endeavour segment of the Juan de Fuca Ridge. The model was derived from active-source data acquired during the ETOMO 3-D seismic tomography experiment conducted during Langseth cruise MGL0910 in 2009 (chief scientists Doug Toomey, Emilie Hooft, William Wilcock). The model and results are described in Arnoux et al. (2019). A three-dimensional, iterative tomographic technique was used to invert 96,155 Pg refraction, 105,000 PmP reflection, and 12,000 Pn refraction arrival times to constrain isotropic slowness and seismic anisotropy within the crust and topmost mantle, in addition to Moho depth. The data set is in ASCII format and contains longitude, latitude, and P-wave velocity perturbations (dVp) relative to a depth-dependent, off-axis velocity average. The P-wave velocity perturbations are given at depths of 0.6, 1.2, 1.8, 2.4, 3.0, 3.6, 4.2, 5.2, 5.8, and 7.8 km depth below seafloor. All depths are masked in regions of poor ray coverage and poor resolution. This data set was generated as part of the projects called (1) ETOMO: Endeavour Seismic Tomography Experiment and Testing Models of Magmatic and Hydrothermal Segmentation: A 3-D Seismic Tomography Experiment at the Endeavour Ridge and (2) Next-generation 3D imaging of the on- and off-axis mantle and crustal magmatic systems at the Endeavour segment.

Processed Multi-Channel Seismic Data off South Island, New Zealand, acquired during R/V Maurice Ewing survey EW9601 (1996)
Author(s): Henyey, Thomas; Okaya, David; Davey, Fred; Stern, Tim
Description: This cruise was part of a joint US-New Zealand multiphase crustal-scale study of the Southern Alpine orogen across the central South Island of New Zealand, extending out to sea on either side of the island. This joint US-NZ investigation of continental deformation at convergent plate boundaries was known as the South Island GeopHysical Transection (SIGHT) project. MCS and OBS/OBH data were collected on the west (Tasman Sea) side and east (Pacific Ocean) side of South Island. At the end of the cruise OBS/OBH and SCS data were collected off Kakanui Point just south of Timaru as part of the Southern Cross Anisotropy Survey. One of the objectives was to improve understanding of continental deformation at convergent plate boundaries by using marine onshore/offshore seismic techniques to provide a detailed image of the plate boundary from both sides.

Processed multichannel seismic data in the Bering and Chukchi seas off Alaska, acquired during the R/V Maurice Ewing survey EW9410 (1994)
Author(s): Miller, Elizabeth; Klemperer, Simon
Description: Stanford University, in conjunction with the U.S. Geological Survey, and with participation by the Institute of the Lithosphere and the Institute of the Russian Academy of Sciences, and the Geodynamics Research Institute of Texas A and M University, conducted deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas, Alaska, during the month of August, 1994. The data was recorded to two-way travel-times of 15 to 23 seconds, with 50-75 m shot spacing. Two north-south transects were profiled. The eastern transect extended from 58 degrees 50'N, 168 degrees 32'W, well within the continental shelf of the Bering Sea, north of the Pribilof Islands, to just south of the shelf edge north of Barrow, Alaska, at 71 degrees 49'N, 154 degrees 33'W. Ice prevented continuation of the line beyond the shelf edge. The western transect extended from the central Chukchi Sea, well within the shelf at 71 degrees 23'N, 163 degrees 00'W, into the Aleutian basin at 58 degrees 00'N, 178 degrees 30'W, near Navarinsky Canyon. An additional short line crossing over the Beringian margin a second time was recorded near Zemchung Canyon east of the western transect. The profiles cross important strike-slip faults, possible terrane boundaries, two continental margins, and several Cretaceous/Tertiary sedimentary basins (Norton, Hope, Chukchi, and Navarin Basins). Together with the preceding cruise EW9409, the profiles provide a continuous transect across the North American continent, from the Pacific to Arctic Ocean. Most of the multi-channel (MCS) data is of high quality, but bad weather, strong currents, and recording problems sometimes presented difficulties during data acquisition. Gravity, magnetic, and sonobuoy data were also recorded along the profiles. Wide-angle recording was done in conjunction with the seismic profiling, at recording sites located along the central west coast of Alaska and the Chukchi Peninsula, as well as on islands in the Bering Strait and Bering Sea. The purpose was to conduct deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas. Funded by NSF grant OCE93-17087.

The eastern transect extended from 58 degrees 50'N, 168 degrees 32'W, well within the continental shelf of the Bering Sea, north of the Pribilof Islands, to just south of the shelf edge north of Barrow, Alaska, at 71 degrees 49'N, 154 degrees 33'W. Ice prevented continuation of the line beyond the shelf edge. The western transect extended from the central Chukchi Sea, well within the shelf at 71 degrees 23'N, 163 degrees 00'W, into the Aleutian basin at 58 degrees 00'N, 178 degrees 30'W, near Navarinsky Canyon. An additional short line crossing over the Beringian margin a second time was recorded near Zemchung Canyon east of the western transect. The profiles cross important strike-slip faults, possible terrane boundaries, two continental margins, and several Cretaceous/Tertiary sedimentary basins (Norton, Hope, Chukchi, and Navarin Basins). Together with the preceding cruise EW9409, the profiles provide a continuous transect across the North American continent, from the Pacific to Arctic Ocean. Most of the multi-channel (MCS) data is of high quality, but bad weather, strong currents, and recording problems sometimes presented difficulties during data acquisition. Gravity, magnetic, and sonobuoy data were also recorded along the profiles. Wide-angle recording was done in conjunction with the seismic profiling, at recording sites located along the central west coast of Alaska and the Chukchi Peninsula, as well as on islands in the Bering Strait and Bering Sea. The purpose was to conduct deep seismic investigations of the continental crust beneath the Bering and Chukchi Seas. Funded by NSF grant OCE93-17087.

Processed multichannel seismic data along the Galapagos Spreading Center at 91.3W - 95.5W, acquired during the R/V Maurice Ewing survey EW0004 (2000)
Author(s): Sinton, John; Mahoney, John; Ito, Garrett; Lin, Jian; Graham, David
Description: Part of the Galapagos Plume-Ridge Interaction Multidisciplinary Experiment (G-Prime), this MCS-OBS survey characterized in detail the oceanic created along the Galapagos Spreading Center at 91.3W - 95.5W. The objectives of the project were to: (1) determine how the compensation of the Galapagos swell is partitioned between variations in crustal thickness and mangle density by measuring crustal thickness along the swell and the degree of melting inferred from the chemistry of basalts, (2) determine if there is a threshold factor that controls the transition from an axial high to a rift valley, (3) determine how the extent of magmatic differentiation of ridge basalts relates to the presence or absence of a melt lens, and (4) determine why the degree of partial melting appears to be lower near the hotspot.

Shallow Upper Crustal Seismic Velocity Structure of Santorini Volcano, Greece (Heath, et. al., 2019)
Author(s): Heath, Benjamin; Hooft, Emilie; Toomey, Douglas; Papazachos, Costas; Nomikou, Paraskevi; Paulatto, Michele; Morgan, Joanna; Warner, Michael
Description: This data set, presented in Heath et al. (2019), consists of a P-wave tomographic model of Santorini Volcano and the surrounding region including the Christiana and Anydros Basins as well as the Kolumbo Volcanic Field. The model was derived from dense active-source data with airguns fired from the ship to an array of ocean-bottom and land seismometers during the PROTEUS experiment on cruise MGL1521 (chief scientist Emilie Hooft). Using standard isotropic tomographic techniques, the model was created by inverting ~200,000 P-wave travel-times of rays that sampled the upper crust. The data files are in NetCDF format (suitable for importing to GMT scripts), gridded at approximately 100m resolution. The “Vel-*.grd” files consists of lat/lon and dv values, where the latter measures the deviation of seismic velocity from a depth dependent velocity average. We present velocities at depths of 0, 1, 2, and 3 km which are conformal to the bathymetry/topography. Files labeled with “Velwithdws” consist of lat/lon/dv values where regions of poor ray coverage and poor resolution are masked out. This data set was generated as part of the Plumbing Reservoirs Of The Earth Under Santorini (PROTEUS) experiment, with funding provided by NSF grant OCE14-59794 and Leverhulme Grant RPG-2015-363.

Catalog of earthquakes at Axial Seamount relocated with three-dimensional P- and S-wave velocity models from a joint inversion of earthquake arrival times for velocity and hypocentral parameters
Author(s): Baillard, Christian; Wilcock, William
Description: This data set comprises an earthquake catalog derived by relocating earthquakes on Axial Seamount from January 2015 through February 2017 using 3-D P-wave and S-wave velocity models obtained from a joint inversion of earthquake P-wave and S-wave arrival times for velocity structure and earthquake locations. The arrival times were obtained from the seismic network on the Ocean Observatories Initiative Cabled Array at Axial Seamount. The study that obtained the catalog is described in Baillard and Wilcock (2019). The catalog is presented in two files, one that includes only hypocenters and one that includes both hypocenters and phase information. Both files are in NonLinLoc format. NonLinLoc is documented in general at http://alomax.free.fr/nlloc/ and the specific format for the catalog files is documented at http://alomax.free.fr/nlloc/soft7.00/formats.html#_location_hypphs_. The data files were generated as part of a project called Understanding the Spatio-Temporal Characteristics of Earthquakes at Axial Seamount Late in an Eruptive Cycle, and funding for this work was provided by NSF award OCE-1536219.

Processed multichannel seismic data at the Blanco Transform in the Pacific Ocean, acquired during R/V Maurice Ewing expedition EW0410 (2004)
Author(s): Christeson, Gail; Nakamura, Yosio; McIntosh, Kirk
Description: The Blanco Transform Seismic cruise acquired marine seismic reflection and refraction data at the Blanco Transform in the Pacific Ocean. A companion program, EW0305, took place in 2003 where fast-spreading oceanic crust is exposed at Hess Deep. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas? Funding was provided by NSF grants OCE-0137286.

Processed high-resolution gridded multibeam bathymetry data from the New England Mud Patch
Author(s): Goff, John; DeMoustier, Christian; Wilson, Preston; Knobles, David
Description: These multibeam bathymetry grids were collected in 2015 aboard the R/V Sharp, as part of the Office of Naval Research-sponsored Seabed Characterization Experiment (https://wwwext.arlut.utexas.edu/sbcex/). The rectangular survey region, oriented ~E-W in ~60-80 m water depths, measured ~11 km wide and 30 km long. It included 42 strike (E-W) lines spaced ~250 m apart that were used to form the data grids. Multibeam data were collected using a Reson 7125 instrument operating at 200 kHz, and processed using CARIS software. Differential GPS were used for navigation, and an Applanix POS MV inertial motion unit provided attitude control. Raw bathymetry were corrected for pitch, heave, yaw and roll. Raw bathymetry are also manually edited to remove erroneous echosounder pings, recognizable by large positive or negative anomalies from the norm. Conductivity-temperature-depth (CTD) casts were periodically collected and used to determine water depths from the swath soundings. However, this processing step posed a difficult challenge owing to the rapidly changing water masses in the survey region, which was influenced by eddies from the nearby Gulf Stream; CTD readings were insufficiently sampled both in time and space to adequately characterize the variability of the sound speed profile. Incorrect assumptions about sounds speed profile cause the cross-swath profile to either curve upwards (“smile” artifacts) or downward (“frown” artifacts). These effects can be empirically corrected within CARIS, but result in added uncertainty in the overall depth which are often expressed as mismatch between adjacent swaths. The data files are in NetCDF format (suitable for importing to GMT scripts), gridded at 1m to enhance visualization of small-scale features, which are numerous. Projection is in UTM Zone 19N. To keep file sizes manageable, the data grids are sectioned into eastern, central and western subregions. DOI: 10.1594/IEDA/324799

Processed multichannel seismic data at the Blanco Transform in the Pacific Ocean, acquired during R/V Maurice Ewing expedition EW0410 (2004)
Author(s): Christeson, Gail; Nakamura, Yosio; McIntosh, Kirk
Description: The Blanco Transform Seismic cruise acquired marine seismic reflection and refraction data at the Blanco Transform in the Pacific Ocean. A companion program, EW0305, took place in 2003 where fast-spreading oceanic crust is exposed at Hess Deep. The primary objective of the cruise was to make a direct link between the geologic and seismic structure of intermediate-spreading oceanic crust. Questions that were to be addressed by the seismic experiments include: 1) Is there a correlation between seismic and geologic structure at the Blanco Transform? 2) Is the seismic structure at the Blanco Transform typical of intermediate-spreading crust? 3) What is the evolution of the shallow velocity structure from zero-age rise-axis crust to the 0.65-1.65 Ma crust in the study areas? Funding was provided by NSF grants OCE-0137286.

Water column data collected from moorings in Monterey Canyon, offshore California
Author(s): Paull, Charles; Talling, Peter; Maier, Katie; Parsons, Daniel; Xu, Jingping; Rosenberber, Kurt
Description: These water column data files were collected in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. A dense array of sensors (more than 50) were deployed for three consecutive six-month periods from October 2015 to April 2017 in Monterey Canyon between 280 and 1850 m water depth. Instruments were mounted on moorings between 10 and 300 m above the seafloor. The data files are in netCDF format and include the following types of data: Optical and acoustic backscatter, transmissivity, conductivity, temperature, pressure, salinity, wave height and current velocity, fluorescence, dissolved oxygen, and altimetry. File names begin with MBCCE, then mooring name, followed by an abbreviation for the sensor, and then the deployment date (yyyymmdd). For more specific information about each data file, download the excel file "CCE Files and Stations" and review the "Science Report" under Documents. Funding for the project was provided by The David and Lucile Packard Foundation, Natural Environment Research Council (NE/K011480/1), U.S. Geological Survey, Ocean University of China, and Qingdao National Laboratory for Marine Science and Technology.

Grain size data for sediment cores collected in the water column of Monterey Canyon, offshore California
Author(s): Paull, Charles; Talling, Peter; Maier, Katie; Parsons, Daniel; Xu, Jingping; Rosenberber, Kurt
Description: Sediment grain size data from Anderson sediment trap samples collected in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Anderson sediment traps are designed to passively collect particulate material as it settles from the water column into a tube. This effectively provides a record of the sediment and particulate matter passing through the water column. Sediment traps were deployed on moorings for three consecutive six-month periods from October 2015 to April 2017. After recovery these tubes were logged with a multi-sensor core logger and a CT scanner and subsequently extruded, and sampled. The grain size data files are in Excel spreadsheet multi-tab format. File names begin with MBCCE, then mooring name, followed by sediment trap name, height above the bottom, and then the deployment date (yyyymmdd). For more specific information about each data file, download the excel file "CCE Files and Stations" and review the "Science Report" under Documents. Funding for the project was provided by The David and Lucile Packard Foundation, Natural Environment Research Council (NE/K011480/1), U.S. Geological Survey, Ocean University of China, and Qingdao National Laboratory for Marine Science and Technology.

Motion and pressure data recorded with Benthic Event Detectors (BEDs) in Monterey Canyon, offshore California
Author(s): Paull, Charles; Gwiazda, Roberto
Description: Benthic Event Detectors (BEDs) were placed in Monterey Canyon as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. BEDs are "smart boulders" that record time-stamped acceleration, rotation, and ambient pressure data. Each BED device is a 43 cm diameter sphere with 2.1 g/cc density in air, 1.0 g/cc density in water. The experimental design of the CCE called for having BEDs on the canyon floor at 200, 300 and 400 m water depth. Within logistical constraints, after BEDs moved during sediment flows, these depths were repopulated with newly-deployed BEDs. A total of 11 BEDS and two AMT/BED deployments took place during the CCE. BEDs deployed multiple times are denoted with A, B and C for each deployment. CU indicates a cubic shaped bed. The data file is an Excel spreadsheet that includes tide-adjusted depth of the BEDs during sediment gravity flows. BED deployment locations are listed under Station Information. For additional information about the BEDs, review the "Science Report" and download the file "CCE BED Deployment Locations" under Documents. Funding for the project was provided by The David and Lucile Packard Foundation, Natural Environment Research Council (NE/K011480/1), U.S. Geological Survey, Ocean University of China, and Qingdao National Laboratory for Marine Science and Technology.

High-resolution (1m) bathymetric data from Monterey Canyon, offshore California
Author(s): Paull, Charles; Caress, David
Description: The processed bathymetric grids were generated from high-resolution, multibeam bathymetric surveys of the Monterey Canyon floor. Two sites were surveyed 6 times each between October 2015 and April 2017 with an MBARI mapping AUV (Autonomous Underwater Vehicle) as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon and their effect on the bathymetry. Repeat surveys captured changes in bathymetry during the experiment. The AUV carried a Reson 7125 multibeam echo-sounder (vertical precision of 0.15 m and horizontal resolution of 1.0 m). An inertial navigation system combined with a Doppler velocity logger allowed the AUV to fly pre-programmed grids at 3 knots, while maintaining an altitude of 50 m above the seafloor, to obtain a nominal line spacing of 130 m. These data files have been cleaned, and tide corrected. A significant effort was made to co-register all the surveys together at each site (CCE_Shallow and CCE_DEEP) using MBnavadjust, part of MBSystem. The shallow surveys were conducted in water depths between 200-500 m and the deep surveys were in water depths of 1350-1880 m. The data files are in netCDF grid format with horizontal 1 m resolution and are projected into UTM zone 10N. The grid files are compatible with GMT programs and MBSystem. For more information about the grids review the "Science Report" under Documents. Funding for this part of the project was provided to investigators Charles Paull and David Caress by The David and Lucile Packard Foundation. DOI: 10.1594/IEDA/324756

Range, orientation, temperature and pressure data recorded with AMT beacons in Monterey Canyon, offshore California
Author(s): Paull, Charles; Talling, Peter; Maier, Katie; Parsons, Daniel; Xu, Jingping; Rosenberber, Kurt
Description: An array of three Sonardyne Acoustic Monitoring Transponders (AMTs) was placed in Monterey Canyon to monitor small scale seafloor movements (creep) as part of the Monterey Canyon Coordinated Canyon Experiment (CCE). The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Each instrument was in place for deployments lasting up to six months beginning in October 2015 and October 2016. One AMT was placed at 300 meters water depth in the canyon axis and the other two on stable benches on the canyon sides. The central AMT, deployed in the axis on a large (800 kg, >2 m tall) frame, also had a BED mounted to the side. Each AMT recorded the acoustic range to the other instruments as well as pitch, roll, temperature, and depth every 45 minutes. The data files are in ASCII comma-separated format. File names begin with MBCCE, then mooring name, followed by the date range of the collected data (yyyymmdd to yyyymmdd). For more specific information about each data file, download the excel file "CCE Files and Stations" and review the "Science Report" under Documents.

High-resolution bathymetric data (KMZ format) of the head of Martínez Channel and of Steffen fjord (Chilean Patagonia, 48°S)
Author(s): Vandekerkhove, Elke; Bertrand, Sebastien; Crescenzi-Lanna, Eleonora; DeRycker, Koen; Mansilla, Rodrigo
Description: The bathymetry was mapped with an ELAC Seabeam 1050 multibeam system in austral winter 2016. A mounting frame holding two 50 kHz transducers at a 120-degree angle, was installed at the bow of the R/V Sur Austral (COPAS Sur-Austral, Chile). In order to correct for roll, pitch, and heave movements, an Octans Motion Sensor (IXSEA) was placed on the mounting pole above the transducers. CTD measurements were continuously recorded at the water surface (approximately 1 m depth) using a Valeport Modus CTD. To correct for sound velocity changes with depth, a total of 24 vertical CTD profiles were taken with an RBR Maestro, operated at a sampling rate of 6 Hz and vertical speed of 1 m/s. The multibeam data were processed with Caris HIPS and SIPS v9.1, including tide correction based on tide tables at Caleta Tortel (maximum tidal range of 1.9 m). The final bathymetric maps and grids were created using Fledermaus v7 and GMT. The data file is in KMZ format. DOI: 10.1594/IEDA/324734

Mask files supplemental to tomographic velocity models from Kardell et al. (2019) - MGL1601 / CREST
Author(s): Kardell, Dominik; Christeson, Gail; Estep, Justin; Reece, Robert; Carlson, Richard
Description: These mask files contain the upper and lower bounds of ray coverage achieved for the tomographic velocity models produced by Kardell et al. (2019). They can be used in GMT to only plot the velocity values constrained by the inversion, while cutting out the lower, unconstrained part of the velocity model. The files contain two columns: the left column gives lateral distance along the velocity model in kilometers; the right column gives depth values, also in kilometers. The first block of values includes the lower bounds of ray coverage and the second block includes the upper bounds. The data set was generated as part of the CREST project: Crustal Reflectivity Experiment Southern Transect (chief scientists Bobby Reece and Gail Christeson).

Two-dimensional (2-D) tomographic P-wave velocity structure of the upper crust between the Mid-Atlantic Ridge and the Rio Grande Rise
Author(s): Kardell, Dominik; Christeson, Gail; Estep, Justin; Reece, Robert; Carlson, Richard
Description: These gridded data files present tomographic models of P-wave seismic velocity structure of the upper 2-3 km of oceanic crust between the Mid-Atlantic Ridge and the Rio Grande Rise. The models were derived from active-source data acquired during the CREST 2-D seismic experiment conducted during Langseth cruise MGL1601 in 2016 (chief scientists Bobby Reece and Gail Christeson). The models and results are described in Kardell et al. (2019). Using a 2-D constant gradient starting model of crustal velocity, iterative tomographic inversions were performed with traveltime picks of refracted arrivals on more than 2000 shot gathers. Traveltime residuals were inverted for 2-D slowness perturbations, and ray paths and traveltimes were predicted using a shortest-path algorithm. Ray tracing was performed on a 2-D grid constrained by seafloor topogrophy from multi-beam measurements and basement topography picked on migrated seismic images. The data set is in netCDF grd format, which can be used in GMT software. It was generated as part of the CREST project: Crustal Reflectivity Experiment Southern Transect. Funding was provided by NSF grants OCE15-37108 and OCE15-37169. DOI: 10.1594/IEDA/324716

Author(s): Mark, Hannah; Lizarralde, Daniel; Collins, John; Miller, Nathan; Hirth, Gregory; Gaherty, James; Evans, Robert
Description: This data set consists of travel times for the mantle refraction, Pn, picked from active-source OBS data collected as part of the NoMelt experiment in the central Pacific. The data set is in ASCII format. For each travel time, the shot line number, station location, and shot location are provided. Before picking, the OBS data were filtered with an 8-pole, minimum phase Butterworth filter with corner frequencies of 4 to 15 Hz, and a linear prediction deconvolution was applied using a filter length of 0.2 seconds and a prediction distance of 0.01 seconds. Travel times were then picked by hand on the vertical ground motion components of station gathers. This data set was generated as part of a project called NoMelt: Structure and evolution of the oceanic lithosphere/asthenosphere system. Funding for this project came from NSF grants OCE09-28663, OCE09-27172, and OCE09-28270. DOI: 10.1594/IEDA/324643

ETOMO: Three-dimensional (3-D) P-wave and S-wave velocity structure of the upper crust beneath the Endeavour segment of the Juan de Fuca Ridge
Author(s): Kim, Eunyoung; Toomey, Douglas; Hooft, Emilie; Wilcock, William; Weekly, Robert; Lee, Sang-Mook; Kim, YoungHee
Description: This 3-D P-wave and S-wave seismic velocity model was derived from active-source data acquired during the ETOMO 3-D seismic tomography experiment that was conducted during Langseth cruise MGL0910 in 2009 (chief scientists Doug Toomey, Emilie Hooft, William Wilcock). Using a 3-D starting model of crustal velocity from previous tomographic studies of crustal refractions, a joint inversion was performed with Pg and Sg crust refraction arrival times using P-to-S coupling constraints. The model and results are described in Kim et al. (2019). The data file is in ASCII format and contains the following 5 columns: x-local-coordinate (km), y-local-coordinate (km), z-local-coordinate (km), P-wave velocity (km/s), and S-wave velocity (km/s). z is depth below the seafloor. The local coordinate is centered on 47.9826N and -129.0776W and rotated -21N. The data set was generated as part of the projects called ETOMO: Endeavour Seismic Tomography Experiment and, Testing Models of Magmatic and Hydrothermal Segmentation: A 3-D Seismic Tomography Experiment at the Endeavour Ridge. Funding was provided by NSF Ridge 2000 program grants OCE04-54747 and OCE04-54700. DOI: 10.1594/IEDA/324623

Catalog of earthquakes detected and located offshore central Oregon, USA, in the Cascadia subduction zone using the Cascadia Initiative amphibious data set
Author(s): Morton, Emily; Bilek, Susan; Rowe, Charlotte
Description: This earthquake catalog spans 26 July 2011 through 1 September 2015 and corresponds to the Geology article of Morton et al. (2018; https://doi.org/10.1130/G45354.1). Events were detected using the subspace detection algorithm of Maciera et al. (2010) and located by utilizing direct P and S phase arrival time picks with the hypoinverse location program (Klein et al., 2002). Events that were previously reported in regional earthquake catalogs and the studies of Tréhu et al. (2015; 2018) and Stone et al. (2018) are indicated, as well as the events that were used as templates for subspace scanning. The catalog includes hypocentral locations, origin time, duration magnitudes, number of seismic picks used in location determination, azimuthal gap, event-to-station distance, and location and timing uncertainties. The catalog is separated into three groupings (three ASCII files separated from the one spreadsheet): Earthquakes within a cluster associated with a subducted seamount (150 events), earthquakes within a cluster to the north of the seamount (73 events), and earthquakes not within the clusters (87 events). The data set was generated as part of the project called Developing Methods for Detection and Analysis of Repeating Earthquakes and Low Frequency Earthquakes Using Cascadia Initiative Amphibious Network Data. Funding was provided by NSF grant OCE14-34550, awarded to S.L. Bilek. DOI: 10.1594/IEDA/324617

Processed high-resolution gridded bathymetry data from Aransas Pass and Lydia Ann Channel (Texas) collected before and after Hurricane Harvey of 2017
Author(s): Goff, John; Allison, Mead; Gulick, Sean
Description: These six processed multibeam bathymetry grids document the submarine morphology of Aransas Pass and Lydia Ann Channel (Texas) in 2009, 2012, and soon after the passage of Hurricane Harvey in 2017. Aransas Pass is the entrance to the Corpus Christi Ship Channel; it connects the Gulf of Mexico to Corpus Christi Bay to the south and, via Lydia Ann Channel, Aransas Bay to the north. The area was heavily impacted by wind damage and surge waters during Hurricane Harvey. The data files are in NetCDF format (suitable for importing to GMT scripts). The 2009 and 2012 data were collected as part of the University of Texas Marine Geology and Geophysics Field Course, which is funded by multiple donations from companies and individuals (see https://ig.utexas.edu/marine-and-tectonics/ut-marine-geology-geophysics-field-course/). The post-hurricane data were funded by the UT Jackson School of Geosciences Rapid Response Endowment. The three surveys were conducted with a Reson Seabat 8101 (2009), 7101 (2012) and T50-P (2017), with boom-mounted transducers affixed to coastal research vessels. Data were processed using Caris software. Depths are in meters. Mercator projection with WGS84. Navigation and boat attitude were determined with differential GPS and an Applannix IMU. Tide corrections from a local station were applied. However, in comparing different years we found roughly constant offsets in the depths to fixed and immutable objects on the seafloor (including two ship wrecks in Lydia Ann Channel, and jetty bollards in Aransas Pass); the cause of these offsets is not certain. This induced us to apply a constant correction to the 2009 and 2012 data sets (see headers) to align with the 2017 data. DOI: 10.1594/IEDA/324572

Data sub-set from specific flow events only - Water column velocity and backscatter data collected during three sediment gravity flow events in Monterey Canyon as part of the Coordinated Canyon Experiment (investigators C. Paull, P. Talling, K. Maier, D. Parsons, J. Xu)
Author(s): Paull, Charles; Talling, Peter; Maier, Katie; Parsons, Daniel; Xu, Jingping
Description: This is a sub-set of the data from the Coordinated Canyon Experiment (CCE) that specifically pertains to the published paper, Paull et al., 2018 Powerful turbidity currents driven by dense basal layers Nat Comms 9. doi: 10.1038/s41467-018-06254-6. The full data set is available at http://get.iedadata.org/doi/324762. The CCE was set up to measure the passage of sediment gravity flows down Monterey Canyon. Raw velocity data and raw backscatter data associated with three flow events are provided. The events took place on January 15th 2016, September 1st 2016 and November 24th 2016. The data from the first two events was collected from six moorings MS-1 (300 m water depth), MS-2 (500 m water depth), MS-3 (800 m water depth), MS-4 (1285 m water depth), MS-5 (1449 m water depth), and MS-7 (1850 m water depth), and from a Seafloor Instrument Node (SIN) at 1840 m water depth. Data for the November 24th 2016 event from the MS-1 moorings is also provided. The moorings held downward-looking ADCPs positioned 65 to 70 m above the seafloor. In the SIN, the ADCP’s were at the seafloor looking upwards. All instruments were synced initially on the same time base. MS-1 broke loose during the January 15th 2016 event and the ADCP kept recording while the mooring traveled down canyon and ultimately surfaced. The ADCP at MS-4 did not collect data during the September 1st 2016 event. File names start with the mooring name followed by the type and frequency of ADCP, and the date of the event. Files contain velocity and backscatter data over time. Times are UTC, except for the SIN data from the January 15th 2016 event, which is in local time (UTC is 7 hours ahead). Velocities are reported in millimeters per second and backscatter is reported in the output units of the ADCP, Echo Intensity Units (EIC), which are proportional to decibels. Files were converted to ASCII text format from the RDI proprietary format. Funding was provided by The David and Lucile Packard Foundation, Natural Environment Research Council (NE/K011480/1), U.S. Geological Survey, and Ocean University of China. DOI: 10.1594/IEDA/324529

Seafloor Magnetization image data, Reykjanes Ridge, Langseth cruise MGL1309 (2013, investigators Fernando Martinez and Richard Hey)
Author(s): Martinez, Fernando; Hey, Richard
Description: This three-dimensonal seafloor magnetization data was derived from the magnetic anomaly data. To carry out the inversion for seafloor magnetization the MGL1309 magnetic anomaly grid was extended within a rectangular area using regional gridded values from Macnab et al. (1995) and ship data from Searle et al. (1998) regridded in ~1 km cells. The multibeam bathymetry grid was extended within the same rectangular area using satellite-predicted bathymetry (Sandwell et al., 2014) to fill areas outside the multibeam coverage and regridded in ~1 km cells. The grids were mirrored to minimize edge effects and a three-dimensional Fourier inversion for seafloor magnetization (Parker, 1972) was carried out using Mirone Software (Luis, 2007) assuming a 500 m source layer with magnetization direction given by the axial geocentric dipole. Five terms in the Fourier series were used in the inversion. The resulting values were masked to the extent of the MGL1309 multibeam grid. As the polarity transitions agreed well with two-dimensional reversal modeling of profile values no annihilator was added. The data file is in PDF format. It is cited in Martinez and Hey, 2017, and was generated as part of the project called Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization. Funding was provided by NSF award OCE11-54071.

Gravity Free-Air Anomaly data, Reykjanes Ridge, Langseth cruise MGL1309 (2013, investigators Fernando Martinez and Richard Hey)
Author(s): Martinez, Fernando; Hey, Richard
Description: The free-air gravity anomaly grid was derived from raw gravity data acquired with a Bell BGM-3 gravimeter and converted to mGal values using the meter constant. A 10 minute cosine taper was then applied to the 1 second values and output at 10 second intervals. Eötvös corrections for ship speed, course and latitude were also applied. The values were adjusted to the gravity tie value at Reykjavik, Iceland, and the International Gravity Formula correction using WGS84 ellipsoid parameters was removed to yield the free-air anomaly. The gravity survey was conducted at the southern end of the Reykjanes Ridge, a segment of the Mid-Atlantic Ridge, in 2013 during Langseth cruise MGL1309 (investigators Fernando Martinez and Richard Hey). The data file is in netCDF:GMT grid format.

High-Temperature time-series raw data from hydrothermal vents at Axial Seamount, Juan de Fuca Ridge, acquired from 1998 to the present (investigator William Chadwick)
Author(s): Chadwick, William
Description: This raw temperature data set was acquired with high-temperature HOBO and MISO probes (range 151-419°C) placed in hydrothermal vents at Axial Seamount on the Juan de Fuca Ridge. The probes were deployed for periods of one to several years beginning in 1998. After each deployment each probe was recovered and serviced, the data was downloaded, and the probe was redeployed often at a different vent site. The file names start with the probe ID, followed by the deployment cruise name/year, and end with the vent name. The MISO probes have 2 chips for redundancy and that is reflected in their file names. The files are in text (ASCII) format and were generated as part of a long-term monitoring project at Axial Seamount. Funding was from NSF grants OCE15-46616, OCE13-56839 and OCE11-55849, OCE07-25605 and NOAA/PMEL grants NOAA-8284-2017, NA16OAR4320152, and NA11OAR4320091. DOI: 10.1594/IEDA/324412

Description: This data set contains shapefiles showing the location of the 2-D electrical resistivity tomography profiles acquired in July 2015 in the Karonga area of northern Malawi Rift. The ERT profile data was collected using a dipole–dipole array with an Iris Syscal Pro 10-channel resistivity meter. There were 72 electrodes with 10 m electrode spacing. Profile 1 is a NNW-SSE profile along the trend of the surface ruptures. Profiles 2 and 3 are roughly E-W profiles oriented perpendicular to and across the trend of the surface ruptures. Profile 1 is 1070 m long, and Profiles 2 and 3 are 710 m long. The data files are in shapefile format. They were generated as part of the projects called Integrated studies of early stages of continental extension: From incipient (Okavango) to young (Malawi) rifts, and IRES: Research Opportunities in Continental Rift Initiation for U.S. Undergraduate Geoscience Students in Malawi.

2-D Electrical Resistivity Tomography (ERT) Data for Karonga, Northern Malawi Rift (2015, investigators Estella Atekwana, Daniel Lao-Davila, Folarin Kolawole)
Author(s): Atekwana, Estella; Lao-Davila, Daniel; Kolawole, Folarin
Description: This data set contains processed 2-D electrical resistivity tomography data acquired in July 2015 in the Karonga area of northern Malawi Rift. It was collected using a dipole–dipole array with an Iris Syscal Pro 10-channel resistivity meter. There were 72 electrodes with 10 m electrode spacing. The goal of the survey was to image the structure of the near-surface deformation along the trend of coseismic surface rupture of the St. Mary Fault associated with the 2009 Mw 6.0 Karonga, Malawi earthquake. The data consists of a NNW-SSE profile along the trend of the surface ruptures (Profile 1), and two roughly E-W profiles oriented perpendicular to and across the trend of the surface ruptures (Profiles 2 and 3). Profile 1 is 1070 m long, and Profiles 2 and 3 are 710 m long. The ERT data contains topography information. The data files are in the RES2DINV software ASCII format. More information on the format can be found in the RES2DINV manual at http://www.geotomosoft.com/downloads.php.

Description: The Total Magnetic Intensity (TMI) data for the Karonga area of Northern Malawi (IGRF not subtracted) between 9.69S-10.09S and 33.79E-34.09E. This processed airborne magnetic data set is a subset of the Southern African Development Community (SADC) airborne magnetic data set which covers the entire area of southern Africa. The data was acquired in 1984-1985, with a flight elevation of 120 m along NE–SW lines with spacing of 1 km. The tie lines were oriented NW–SE and spaced 10 km apart. The data was gridded at 95 m cell size using a minimum curvature algorithm. The data set is cited in Kolawole et al. (2017) in which it was used as part of the project called "Active deformation of Malawi Rift North Basin hinge zone modulated by reactivation of pre-existing Precambrian shear zone fabric". Funding was provided by NSF award EAR 1009988. The data file is in ASCII CSV format. This data set is shared with other researchers for the purpose of research in Malawi only. The Council for Geosciences, South Africa has to be acknowledged as the source of the data. Detailed information on the acquisition parameters for this data (e.g. magnetometer sensor used, acquisition dates, geophysical contractor etc.) can be obtained from the The Council for Geosciences, South Africa.

Stacked receiver functions and station orientation estimates for Cascadia OBS stations (investigators Janiszewski, Gaherty, Abers)
Author(s): Janiszewski, Helen; Gaherty, James; Abers, Geoffrey
Description: This data set contains a station information table and a set of stacked receiver function data files. For each OBS station in the StationInfo file, a file exists containing the stacked receiver function for that station under the name Network_StationName_RFStack. The receiver functions are calculated in the vertical-radial-transverse coordinate system and filtered with a 0.1 Hz high pass prior to deconvolution. The time-domain iterative deconvolution method of Ligorria and Ammon (1999) is used to calculation the radial component receiver function from earthquakes that had visible P-wave arrivals. Signals are filtered with a low-pass Gaussian filter during the deconvolution; the data presented here have been filtered with a corner at 0.4 Hz. Each station stack is calculated as a linear stack without move-out correction, normalized by the number of earthquakes that were included. The receiver function data files are in ASCII format and contain two columns. The first column is the time axis in seconds where the zero time is aligned with the P-wave arrival. The second column is the stacked receiver function. The README file included with this archive provides a complete description of the processing that produced the time series. The ASCII station information table contains orientation estimates for the OBS stations. The receiver functions were used to re-calculate the OBS horizontal orientations by performing a grid search for maximum radial component receiver function energy from 0-360 degrees. These values and their uncertainty ranges are given for each OBS in the final three columns of the StationInfo file. The OBS data was acquired during the Cascadia Initiative program. The data files presented here were generated as part of a project called Thermal structure, hydration and dehydration of the entire Juan de Fuca Plate. Funding for this project came from NSF grant OCE13-34831. The data set is referenced in Janiszewski and Abers, 2015. DOI: 10.1594/IEDA/324272

COAST: Heat flow derived from Bottom Simulating Reflectors (BSR) at the Cascadia Subduction Zone (investigators H. Paul Johnson, Evan Solomon, Robert Harris, Marie Salmi)
Author(s): Johnson, H.Paul; Solomon, Evan; Harris, Robert; Salmi, Marie
Description: This heat flow data set was derived from Bottom Simulating Reflectors (BSR) imaged using active-source multi-channel seismic data acquired during the Cascadia Open Access Seismic Transects (COAST) survey conducted in 2012 along the Southern Cascadia Margin during R/V Langseth expedition MGL1212. The heat flow data and processing steps are described in Salmi et al., 2017. From each multi-channel seismic profile, the seafloor and BSR travel times were picked, and assuming 50% lithostatic/hydrostatic pressure and normal saline water, the temperatures were estimated. Thermal conductivity was assumed to follow the relationship provided by Davis et al., 1990 which correlates well with borehole data off Vancouver Island. The data file is in ASCII format and contains individual profile line number, common depth point (CDP), latitude, longitude, heat flow and its uncertainty, and seafloor depth derived from multibeam bathymetry also collected during cruise MGL1212. Funding was provided by NSF grants OCE11-44164 and OCE12-49552. Raw geophysical and seismic data can be downloaded from the Lamont-Doherty Earth Observatory Web site (http://www.marine-geo.org/tools/search/entry.php?id=MGL1212). Seismic profiles processed shipboard through post-stack time migration can be downloaded from the University of Texas Institute for Geophysics seismic database (http://www-udc.ig.utexas.edu/sdc/cruise.php?cruiseIn=mgl1212).

Raw CHIRP towed sub-bottom data from the Beaufort Sea, Healy cruise HLY1302 (2013, investigators Lloyd Keigwin and Neal Driscoll)
Author(s): Keigwin, Lloyd; Driscoll, Neal
Description: Raw seismic reflection sub-bottom data collected with a towed Edgetech 512i CHIRP sub-bottom profiler from Scripps Institution of Oceanography. The data files are in SEG-Y format and contain real-time GPS navigation in the header. The CHIRP towfish included a pressure sensor, allowing the depth of the towfish to be taken into account. As a result, the two-way travel time in the raw CHIRP data is referenced from the sea surface not the towfish. The data set was collected in 2013 in the Beaufort Sea during Healy cruise HLY1302 (investigators Lloyd Keigwin and Neal Driscoll) as part of the project titled "Collaborative Research: Testing the Northern Route for Younger Dryas Meltwater". Funding was provided by NSF awards OPP12-04045, OPP12-03944 and PLR12-04112. DOI: 10.1594/IEDA/324150
