Description: The feature class contains bathymetric contours which provide the size, shape and distribution of underwater features. The contours are from zero to -100m with a contour every 10 meters, a -101m to -500m with contours every 25meters, and -501m+ with contours every 100m until all contours had been created for the DEM utilized. The DEM utilized was the Global Multi-Resolution Topography (GMRT) Synthesis which is a multi-resolution gridded global Digital Elevation Model (DEM) that includes cleaned processed ship-based multibeam sonar data at their full spatial resolution (~100m in the deep sea).
