Concept
Scotia Sea
Summary
The Scotia Sea is a sea located at the northern edge of the Southern Ocean at its boundary with the South Atlantic Ocean. It is bounded on the west by the Drake Passage and on the north, east, and south by the Scotia Arc, an undersea ridge and island arc system supporting various islands. The sea sits atop the Scotia Plate. It is named after the expedition ship Scotia. Many icebergs melt there.
The Scotia Sea is the area of water between the Drake Passage, Tierra del Fuego, South Georgia, the South Sandwich Islands, the South Orkney Islands, and the Antarctic Peninsula. These island groups all sit atop the Scotia Arc, which frames the sea on the north, east, and south. The Scotia Sea covers an area around . About half of the sea stands above the continental shelf.
The sea was named about 1932 after the Scotia, the expedition ship used in these waters by the Scottish National Antarctic Expedition (1902–04) under William S. Bruce. The most famous traverse of this frigid sea was made near the end of the Imperial Trans-Antarctic Expedition in 1916 by Sir Ernest Shackleton and five others in the adapted lifeboat James Caird. They left Elephant Island, just off the tip of the Antarctic Peninsula and reached South Georgia Island two weeks later. It was a distance of nearly 900 miles and the sun was only sighted four times during the entire journey.
In Argentina, the Scotia Sea is considered part of an area known as the Mar Argentino, and several territories claimed but not occupied by Argentina, such as South Georgia and the Falkland Islands, lie within this region.
The islands bordering the Scotia Sea are rocky and partly covered in ice and snow year round; despite these harsh conditions, however, the islands do support vegetation and have been described as the Scotia Sea Islands tundra ecoregion, which includes South Georgia, the volcanic South Sandwich Islands, and the South Orkneys in the Scotia Sea, as well as the remote South Shetland Islands near the Antarctic Peninsula and the small isolated volcano called Bouvet Island.
