AT11-07 Backscatter:Acoustic, Bathymetry:Swath, Sidescan
Processed ship-based Multibeam Sonar Data (version 2) acquired at the East Pacific Rise Spreading Center at 9 North during the Atlantis expedition AT11-07 (2004)
This data set was acquired with a ship-based SeaBeam 2112 Multibeam Sonar system during Atlantis expedition AT11-07 conducted in 2004 (Chief Scientist: Dr. Hans Schouten). These data files are of MBSystem format and include Sidescan, Swath Bathymetry, and Acoustic Backscatter data and were processed by the GMRT Team using the open source MB-System multibeam sonar processing software as part of the GMRT Synthesis effort. These data are included in the GMRT Synthesis, version 2.3. Data were acquired as part of the project(s): Microbial Biofilms and Fluid Chemistry on Larval Settlement at Deep-sea Hydrothermal Vents, Central Anomaly Magnetic High: Constraints on the Volcanic Construction and Architecture of Young Upper Oceanic Crust, In-Situ Sensors for Monitoring the Chemistry of Hydrothermal Fluids, and Establishing a Role for Fe and S Microbial Metabolism in Ocean Crust Weathering, and funding was provided by NSF grant(s): OCE01-17117, OCE02-41791, OCE98-19261, and DOEI-TS03.
Device Info
The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).
