50 Meter Grids (GMT and Arc)
A complete synthesis (shown above) can be downloaded in both ESRI grid format as well as GMT netcdf format. However, do to the large size of the complete synthesis, tiles (1 degree x 1 degree blocks) have been generated and are also available for download. These tiles can be combined to generate the complete synthesis as well (directions are provided here).

Regional Grid (1 km x 1km)
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.
