Processed ship-based Multibeam Sonar Data (version 2) acquired off the coast of Central America in the Caribbean Sea during the Marcus G. Langseth expedition MGL0804 (2008)

This data set was acquired with a ship-based Kongsberg EM120 Multibeam Sonar system during Marcus G. Langseth expedition MGL0804 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 1, and funding was provided by NSF grant(s): OCE04-05556, OCE04-05572, OCE04-05608, OCE04-05654, OCE05-20378, and OCE06-25178.
