NASA Earth Observations (comp.) 20260316 131430-0400 raster digital data https://neo.gsfc.nasa.gov/view.php?datasetId=GEBCO_BATHY Beneath the waters of the world's ocean, the Earth's surface isn't flat like the bottom of a glass or large bowl. There are giant mountain ranges and huge cracks where the ocean floor is ripping apart. Underwater volcanoes are slowly building up into mountains that may one day rise above the sea surface as islands. Because of these features, the depth of the water isn't the same everywhere in the ocean. Bathymetry is the measurement of how deep the water is at various places and the shape of the land underwater. In these maps, different shades of color represent different water depths. The data come from the General Bathymetric Chart of the Oceans, produced by the International Hydrographic Organization (IHO) and the United Nations' (UNESCO) Intergovernmental Oceanographic Commission (IOC).
