GeoSphere satellite mosaic image of the whole Earth showing bathymetry centered on the South Pole. Land cover information from satellite images is merged with an ocean topography model. Notable ocean features include the large, curved Scotia Ridge (upper left), the South-West Indian Ridge (upper right) and the deep Kermadec/Tonga Trench (bottom centre). Only the permanent ice cover of Antarctica is shown here. Near upper left is South America, with its large coastal trench (Peru/ Chile) on the lower side. This is the site of a destructive plate margin, also responsible for the Andes mountain range.
