Processed ship-based Multibeam Sonar Data (version 2) acquired in the Indian Ocean during the Roger Revelle expedition KNOX06RR (2007)

This data set was acquired with a ship-based Kongsberg EM120 Multibeam Sonar system during Roger Revelle expedition KNOX06RR conducted in 2007 (Chief Scientist: Dr. William Sager). These data files are of MBSystem format and include Swath Bathymetry, Sidescan, 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): Geophysical, Geochemical and Geochronological Site Survey of the Ninetyeast Ridge - Testing Hotspot Hypotheses, and funding was provided by NSF grant(s): OCE05-49852 and OCE05-50743.
