Earth, topographic and bathymetric map
Earth, topographic and bathymetric map. This whole Earth map is centred on the Greenwich meridian, at zero degrees latitude. Highlands and lowlands of the continents are shown as ridges and flat areas, with Arctic and Antarctic ice in white. The seabed depth varies from shallow (light blue) on the continental shelves, to deep ocean basins (dark blue). Topographic and bathymetric data is usually gathered by using aerial and satellite imagery combined with radar and sonar mapping. The satellites in this case were NOAA's POES satellites

Ocean currents off the Americas
Ocean currents off the Americas. Satellite-based graphic showing ocean currents (swirling coloured lines) on an Earth globe centred on the Americas. The colours indicate ocean temperatures, ranging from the warm tropics (red) to cooler water (green) in more temperate latitudes. Ocean currents seen here include the warmer Equatorial Counter in the Pacific (centre left), and the Gulf Stream in the Atlantic (upper right). The dusk terminator (day-night line) is at lower right, marking the places from where the Sun is seen setting in the west as the Earth rotates on its axis
