North Pole topography, ETOPO1 model
North Pole topography, ETOPO1 model. Colours on land indicate vegetation (green), dry areas (brown), high mountains (dark brown), and snow and ice (white). On the ocean floors, prominent features include deep waters (dark blue) and continental shelves (light blue). Global, regional and coastal datasets (including GLOBE, Measured and Estimated Seafloor Bathymetry, and SRTM) were used. ETOPO1 (2009) was produced by the National Geophysical Data Center of the National Oceanic and Atmospheric Administration (NOAA).
