Regional Grid (1 km x 1km)

Regional Bathymetry Synthesis

A lower resolution version of the bathymetry synthesis was also made. This version which has a resolution of 1km x 1km is meant for modeling and location maps. The grid is formed by combining the multibeam synthesis along with USGS DEMs and the Smith and Sandwell Measured and Estimated Seafloor Topography.
