Complete 0.5 meters 0.1 to 0.2 meters The bathymetry data were collected along a continuous swath perpendicular to the direction of the ship using a Kongsberg Simrad EM3000 (300 kHz) multibeam sonar system. The data are cleaned of bad navigation and depth soundings. The depth soundings are gridded into a common grid. The gridded data are converted to an XYZ ASCII format file (Longitude, Latitude, Depth in Meters). 20021010 Brian Donahue University of South Florida, College of Marine Science Marine Technician / Research Assistant mailing and physical address
