Processed Multibeam Sonar Data (version 2) from the Ross Sea acquired during Nathaniel B. Palmer expedition NBP0305A (2003)

This data set was acquired with a Kongsberg model EM120 multibeam sonar system during Nathaniel B. Palmer expedition NBP0305A conducted in 2003 (Chief Scientist: Dr. Walker Smith). These data files include Acoustic Backscatter, Sidescan, 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): Interannual Variability in the Antarctic-Ross Sea (IVARS): Nutrients and Seasonal Production, and funding was provided by the U.S. National Science Foundation.
