This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9802 conducted in 1998 (Chief Scientist: Dr. Michael Rawson). These data files are of MBSystem format and include Sidescan, Acoustic Backscatter, and Swath Bathymetry 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 2.1. Data were acquired while the Maurice Ewing was in transit.
