South Georgia (Spanish: Isla San Pedro, Portuguese: Ilha São Pedro / Geórgia do Sul) is an island in the southern Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around 1,400 kilometres (870 mi) east of the Falkland Islands. Stretching in the east-west direction, South Georgia is around 170 kilometres (106 mi) long and has a maximum width of 35 kilometres (22 mi). The terrain is mountainous, with the central ridge rising to 2,935 metres (9,629 ft) at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours.

Discovered by Europeans in 1675, South Georgia had no indigenous population due to harsh climate and remoteness. Captain James Cook in HMS Resolution made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken. The main settlement and the capital today is King Edward Point near Grytviken, a British Antarctic Survey research station, with the population of about 20 people.
The island of South Georgia was probably discovered in 1675 by Anthony de la Roché, a London merchant, and was named Roche Island on a number of early maps. It was sighted by a commercial Spanish ship named León operating out of Saint-Malo on 28 June or 29 June 1756. According to Argentine historians, it was explored on 29 June 1756, St Peter's Day, hence its Spanish name Isla San Pedro, literally "St Peter's Island".
The mariner Captain James Cook in HMS Resolution made the first landing, survey and mapping of South Georgia. As mandated by the Admiralty, on 17 January 1775 he took possession for Britain and renamed the island 'Isle of Georgia' for King George III.
It was from South Georgia that Ernest Shackleton organised the rescue of his party from Elephant Island following the disaster that befell the 1916 Imperial Trans-Antarctic Expedition, which he led. He is buried in the cemetery at Grytviken.
Commercial sealing was conducted on the island between 1786 and 1913. During that period 131 sealing visits are recorded, eight of which ended when the vessel was wrecked. Modern industrial sealing associated with whaling stations was carried out between 1909 and 1964. Sealing era relics include iron try pots, hut ruins, graves and inscriptions.
On 19 March 1982, a group of Argentinians arrived at Leith Harbour and raised the Argentine flag on the island. On 3 April, the second day of the Falklands War, Argentine naval forces occupied the island. South Georgia was retaken by British forces on 25 April during Operation Paraquet.
Geography and faunaEdit
The island is classified as an ET or polar tundra climate on the Köppen-Geiger classification system. It has no tree cover, and there is generally snow on the island during the winter months (April–November). The terrain is mountainous, with a central ridge and many fjords and bays along the coast. Additionally, South Georgia is a breeding ground for elephant seals, fur seals, and king penguins. The island is home to the South Georgia Pintail and the South Georgia Pipit, the only known habitat for these birds.
The island's topography includes a stepped sequence of flat surfaces interpreted as wave-cut platforms formed when sea level was higher relative to the island. At sea level strandflats have been described.
In 2013, teams of Norwegian government shooters and Sami reindeer herders culled all 3,500 reindeer on the island. The animals had been introduced by Norwegian whalers in the early 20th century for food and sport hunting, but were later seen as a pest, damaging the island's flora and wider ecosystem. Karl Erik Kilander, the project manager, said the culled reindeer were frozen and taken to the Falkland Islands where they were sold to local residents and cruise ship operators.
The island lies in the path of large icebergs drifting northward from Antarctica. Iceberg A-38 grounded off the island in 2004, resulting in indirect but severe effects on local wildlife by disturbing life on the seafloor and blocking foraging routes of seals and penguins. In 2020, the colossal 4,200-square-kilometre (1,600 sq mi) Iceberg A-68, similar in size to the island itself, was initially believed to be on a similar collision course but broke apart before collision with the island. Scientists were also relieved that another huge plankton bloom is under way as the iceberg continued to pass, which will further benefit the fish and the seals and penguins that feed on them.
