Processed ship-based Multibeam Sonar Data from the Antarctic Peninsula acquired during the Maurice Ewing expedition EW9101 (1991)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9101 conducted in 1991 (Chief Scientist: Dr. James Austin). These data files are of MBSystem format and include 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 1. Data were acquired as part of the project(s): The Bransfield Strait-South Shetland Islands/Trench: Structural and Stratigraphic Evolution of a Linked(?) Back-arc/Fore-arc System and The Pacific Margin of the Antarctic Pennisula: A Marine Geophysical Study of the Tectonic Evolution of Andean-Type Orogens, and funding was provided by NSF grant(s): DPP89-17332 and OCE94-18135.
