Processed ship-based Multibeam Sonar Data (version 2) acquired off the coast of New Zealand during the Maurice Ewing expedition EW9513 (1995)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9513 conducted in 1995 (Chief Scientist: Dr. Steve Cande). These data files are of MBSystem format and include Acoustic Backscatter, Swath Bathymetry, and Sidescan 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): Early Tertiary Tectonic Evolution of the Pacific-Australia-Antarctic Plate Circuit, and funding was provided by NSF grant(s): OCE94-16779 and OCE94-16989.
