Processed ship-based Multibeam Sonar Data (version 2) acquired off the coast of Central America during the Marcus G. Langseth expedition MGL0807 (2008)

This data set was acquired with a ship-based Kongsberg EM120 Multibeam Sonar system during Marcus G. Langseth expedition MGL0807 conducted in 2008 (Chief Scientist: Dr. W. Steven Holbrook). 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 2.1. Data were acquired as part of the project(s): Collaborative Research: Seismic measurements of magma flux, arc composition, and lower-plate serpentinization in the Central American subduction factory and TICO-CAVA, 2008 Leg 2, and funding was provided by NSF grant(s): OCE04-05556, OCE04-05572, OCE04-05608, OCE04-05654, OCE05-20378, and OCE06-25178.
