MGL2104 Backscatter:Acoustic, Bathymetry:Swath, Sidescan
Processed Acoustic Backscatter, Sidescan and Swath Bathymetry Data from the Cascadia Margin acquired during R/V Marcus G. Langseth expedition MGL2104 (2021)
This data set was acquired with a Kongsberg Maritime EM122 Multibeam Sonar during R/V Marcus G. Langseth expedition MGL2104 conducted in 2021 (Chief Scientist: Dr. Suzanne Carbotte, Investigators: Dr. Jeffrey Beeson, Dr. Suzanne Carbotte). These data files are of MBSystem-compatible format (format 121, Generic Sonar Format) and include Acoustic Backscatter, Sidescan and Swath Bathymetry data that were processed after acquisition. This data was processed by OSU and is included in the Global Multi-Resolution Topography (GMRT) Synthesis (version 4.0). Data were acquired as part of the project(s): Collaborative Research: Illuminating the Cascadia plate boundary zone and accretionary wedge with a regional-scale ultra-long offset multi-channel seismic study. Funding was provided by NSF award: OCE18-27452.
