Processed ship-based Multibeam Sonar Data (version 2) acquired near the Lau Back-arc Basin during the Roger Revelle expedition RR0915 (2009)

This data set was acquired with a ship-based Kongsberg EM122 Multibeam Sonar system during Roger Revelle expedition RR0915 conducted in 2009 (Chief Scientist: Dr. Douglas Wiens). 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 2.4. Data were acquired as part of the project(s): Crustal Accretion and Mantle Processes Along the Subduction-Influenced East Lau Spreading Center, and funding was provided by NSF grant(s): OCE04-26369, OCE04-26408, and OCE04-26428.
