A bathymetric terrain model of the Atlantic Margin covering almost 725,000 square kilometers of seafloor from the New England Seamounts in the north, to the Blake Basin in the south is compiled from existing multibeam bathymetry data for marine geological investigations. Although other terrain models of the same area are extant, they are produced from either satellite-derived bathymetry at coarse resolution (ETOPO1), or use older bathymetry data collected using a combination of single beam, and multibeam sonars (Coastal Relief Model). The new multibeam data used to produce this terrain model have been edited using hydrographic data processing software to maximize the quality, usability, and cartographic presentation of the combined 100-meter resolution grid. The final grid provides the largest, high resolution, seamless terrain model of the Atlantic Margin.
