Processed Multibeam Sonar Data (version 1) near the Antarctic Peninsula acquired during Nathaniel B. Palmer expedition NBP0104 (2001)

This data set was acquired with a SeaBeam Instruments model 2112 multibeam sonar system during Nathaniel B. Palmer expedition NBP0104 conducted in 2001 (Chief Scientist: Dr. Peter Wiebe). These data files include Acoustic Backscatter, 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): SO GLOBEC: Water-column nutrient analysis; SO GLOBEC: Water-column phytoplankton primary productivity; SO GLOBEC: Seabird distribution and abundance; SO GLOBEC: Krill distribution, physiology, and predations; Copepod prey abundance; SO GLOBEC: Mesoscale Circulation, Tides, and Mixing; SO GLOBEC: Hydrographic modeling, both biological and physical, and funding was provided by the U.S. National Science Foundation.
