Processed ship-based Multibeam Sonar Data acquired along the East Pacific Rise (EPR) during the Maurice Ewing expedition EW9105 (1991)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9105 conducted in 1991 (Chief Scientist: Dr. James Cochran). These data files are of MBSystem format and include Swath Bathymetry data and were processed by the at-sea science party and the GMRT Team using the open source MB-System multibeam sonar processing software. These data are included in the GMRT Synthesis, version 1. Data were acquired as part of the project(s): A Three-Dimensional Study of Isostasy and Morphology at a 'Superfast' Mid-Ocean Ridge Crest and Flank and Transform, and funding was provided by NSF grant(s): OCE89-11376.
