Processed ship-based Multibeam Sonar Data from the Drake Passage acquired during the Nathaniel B. Palmer expedition NBP1105 (2011)

This data set was acquired with a ship-based Kongsberg EM120 Multibeam Sonar system during Nathaniel B. Palmer expedition NBP1105 conducted in 2011 (Chief Scientist: Dr. Nerida Wilson). These data files are of MBSystem Compatible 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 2.5. Data were acquired as part of the project(s): Using molecular data to test connectivity and the circumpolar paradigm for Antarctic marine invertebrates., and funding was provided by NSF grant(s): ANT10-43749.
