Processed Multibeam Sonar Data (version 1) from the Amundsen Sea and Ross Sea acquired during Nathaniel B. Palmer expedition NBP0001

This data set was acquired with a SeaBeam Instruments model 2112 multibeam sonar system during Nathaniel B. Palmer expedition NBP0001 conducted in 2000 (Chief Scientist: Dr. Stan Jacobs). These data files include Acoustic Backscatter, Sidescan, and Swath Bathymetry data and were processed at sea using the open source MB-System multibeam sonar processing software. These data are included in the GMRT Synthesis, beginning with version 1. Data were acquired as part of the project(s): Glacial History of the Amundsen Sea Shelf; Study of the Circumpolar Deep Water and its Effects on the West Antarctic Ice Sheet and Pine Island Glacier, and funding was provided by the U.S. National Science Foundation.
