Bathymetry Data

The bathymetry data were produced by the NOAA / National Geophysical Data Center (NGDC). The data resolution varies from 5-minute to 1-degree resolution in parts of Asia, South America, northern Canada, and Africa which are data deficient. The image displayed on the output data page was created by resampling the data from 1 meter depth resolution to 25 meter depth resolution and adding a color map. Land topography is ignored.
