Processed ship-based Multibeam Sonar Data acquired along the Izu-Bonin-Mariana Subduction Zone during the Maurice Ewing expedition EW0202 (2002)

This data set was acquired with a ship-based Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0202 conducted in 2002 (Chief Scientist: Dr. Brian Taylor). These data files are of MBSystem format and include Acoustic Backscatter, Sidescan, 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.
