Popis
The Bathymetry of North America map layer shows depth ranges using colors. The image was derived from the National Geophysical Data Center's ETOPO2 elevation data, which is an elevation database gridded at 2-minute resolution, containing elevation and bathymetry for the world. The image was produced from the October 2001 data set.
