EW0114 Bathymetry:Swath

Processed ship-based Multibeam Sonar Data acquired during the Maurice Ewing expedition EW0114 (2001)

This data set was acquired with a ship-based Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0114 conducted in 2001 (Chief Scientist: Dr. James Cochran). These data files are of MBSystem Compatible format and include Swath Bathymetry data and were processed at sea using the open source MB-System multibeam sonar processing software. Data were acquired as part of the project(s): The Effects of Changes in Mantle Temperature on Melt Supply and Crustal Accretion: An MCS Reflection and OBH Refraction Study of the Southeast Indian Ridge, and funding was provided by NSF grant(s): OCE99-11720.
