Processed ship-based Multibeam Sonar Data acquired along the East Pacific Rise (EPR) during the Maurice Ewing expedition EW9708 (1997)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9708 conducted in 1997 (Chief Scientist: Dr. Douglas Toomey). 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): Constraining Mantle Flow, Melt Supply, and Lower Crustal Structure Between the Clipperton and Siqueiros Fracture Zones from a Seismic Undershoot Experiment, and funding was provided by NSF grant(s): OCE01-17715, OCE01-18383, OCE01-18450, OCE01-18597, OCE02-24903, OCE96-33264, OCE96-33814, and OCE96-34132.
