Processed ship-based Multibeam Sonar Data (version 2) acquired along the East Pacific Rise (EPR) during the Marcus G. Langseth expedition MGL0808 (2008)

This data set was acquired with a ship-based Kongsberg EM120 Multibeam Sonar system during Marcus G. Langseth expedition MGL0808 conducted in 2008 (Chief Scientist: Dr. Jeffrey McGuire). These data files are of MBSystem format and include Sidescan, Swath Bathymetry, and Acoustic Backscatter 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 2.2. Data were acquired as part of the project(s): A Seafloor Geodesy Experiment at the Discovery Transform Fault and Oceanic Transform Faulting: Foreshocks, Seismic and Aseismic Slip on the Quebrada, Discovery and Gofar Transforms, and funding was provided by NSF grant(s): OCE02-42117 and OCE03-51143.
