MGL1903 Backscatter:Acoustic, Bathymetry:Swath
GeoPRISMS:Funded
Processed multibeam swath bathymetry and backscatter data from the Alaska-Aleutians area acquired during Langseth cruise MGL1903 (2019) as part of the Alaska Amphibious Community Seismic Experiment (AACSE).
This data set was acquired with a Kongsberg Maritime EM122 Multibeam Sonar during R/V Marcus G. Langseth expedition MGL1903 conducted in 2019 (Chief Scientist: Anne Becel). The data files in this data set are in MBSystem-compatible Generic Sensor Format (GSF) and include Acoustic Backscatter and Swath Bathymetry data. The files were processed during the cruise using QPS Qimera software. Minor additional edits were made to a few files as part of the GMRT data curation process in preparation for incorporating the bathymetry data in GMRT version 3.7.
