EW0412 Bathymetry:Swath

Raw ship-based Multibeam Sonar Data acquired during R/V Maurice Ewing expedition EW0412 (2004)

This data set was acquired with a ship-based Atlas Hydrosweep DS2 Multibeam Sonar system during Maurice Ewing expedition EW0412 conducted in 2004 (Chief Scientist: Dr. Craig Fulthorpe). These data files are of MBSystem Compatible format and include Swath Bathymetry data that have not been processed. Data were acquired as part of the project(s): Effects of Eustatic and Tectonic Forcing on Development of Forearc Basin Sequence Stratigraphy, and funding was provided by NSF grant(s): OCE02-41179.
