South Georgia Island, South Atlantic Ocean

Located in the South Atlantic Ocean due east of Argentina’s southernmost tip, South Georgia Island is entirely covered by snow and ice in this Terra image from 2002. The island is some 170 kilometers long, with a rugged terrain and 11 mountain peaks more than 2,000 meters high. Many boundary layer cumulus clouds fill the atmosphere surrounding the island. The sinewy patterns snaking across the cloud bank (upper left corner) indicate open-cell convection. The island appears to be creating a wake of thicker marine stratocumulus clouds flowing away from its northeast shore. All around the island, phytoplankton appear to be in bloom, giving the deep-blue South Atlantic waters a lighter, more turquoise hue. Sir Ernest Shackleton stopped on South Georgia Island twice, once in 1914 and again in 1915, as part of the Imperial Trans-Antarctic Expedition he led on the ship Endurance. With no permanent human inhabitants, South Georgia Island is now a wildlife sanctuary and home to seals, reindeer, and sea and land birds.
