Processed ship-based Multibeam Sonar Data acquired near the Izu-Bonin-Mariana Subduction Zone during the Maurice Ewing expedition EW0203 (2002)

This data set was acquired with a ship-based Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0203 conducted in 2002 (Chief Scientist: Dr. Simon Klemperer). These data files are of MBSystem 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 1. Data were acquired as part of the project(s): US-Japan Collaborative Research: Multi-Scale Seismic Imaging of the Mariana Subduction Factory, and funding was provided by NSF grant(s): OCE00-01798, OCE00-01938, OCE00-01956, and OCE00-02878.
