Processed Multibeam Sonar Data (version 3) from Drake Passage acquired during Nathaniel B. Palmer expedition NBP0812 (2008)

This data set was acquired with a Kongsberg model EM120 multibeam sonar system during Nathaniel B. Palmer expedition NBP0812 conducted in 2008 (Chief Scientist: Dr. Teresa Chereskin). These data files include Sidescan, Swath Bathymetry, Acoustic Backscatter 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): Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage, and funding was provided by the U.S. National Science Foundation.
