# King George Island (South Shetland Islands)

King George Island (Argentinian Spanish: Isla 25 de Mayo, Chilean Spanish: Isla Rey Jorge, Russian: Ватерло́о Vaterloo) is the largest of the South Shetland Islands, lying 120 km (75 miles) off the coast of Antarctica in the Southern Ocean. The island was named after King George III.

## Geography

King George island has three major bays, Maxwell Bay, Admiralty Bay, and King George Bay. Admiralty Bay contains three fjords, and is protected as an Antarctic Specially Managed Area under the Protocol on Environmental Protection to the Antarctic Treaty.
The Fildes Peninsula, 7 kilometres (4.3 mi) long, forms the SW extremity of the island. It was named from association with nearby Fildes Strait by the UK-APC in 1960.

## History

Chilean scientists have claimed that Amerinds visited the area, citing stone artifacts recovered from bottom-sampling operations in Admiralty Bay; however, the artefacts—two arrowheads—were later found to have been planted.
The island was first claimed for Britain on 16 October 1819, formally annexed by Britain as part of the Falkland Islands Dependencies in 1908, and now as part of the separate British Antarctic Territory. The Island was claimed by Chile in 1940, as part of the Chilean Antarctic Territory. It was also claimed by Argentina in 1943, now as part of Argentine Antarctica, called by the Argentines Isla Veinticinco de Mayo (25 May) in honour of their National Day. The US and Russia do not recognize any Antarctic claim, and have formally reserved their right to claim Antarctic territories.
The island was discovered and named by the British explorer William Smith in 1819, who named it after the then King, George III. It is approximately 95 km (59 mi) long and 25 km (16 mi) wide with a land area of 1,150 square kilometres (444 sq mi). Over 90% of the island's surface is permanently glaciated. In 1821, 11 men of the sealing vessel Lord Melville survived the winter on the island, the first men to do so in Antarctica.
Chile (like Argentina and Great Britain) regards all of the Antarctic Peninsula and South Shetland Islands as part of that country's territory; however, the terms of the Antarctic Treaty allow Chile to colonize the Fildes Peninsula without overtly pursuing its territorial claims.

## Ecology

The coastal areas of the island are home to a comparatively diverse selection of animal life, including elephant, Weddell, and leopard seals, and Adelie, chinstrap and gentoo penguins. Several other seabirds, including skuas and southern giant petrel, nest on this island during the summer months.
In 1971, Denis C. Lindsay published Vegetation of the South Shetland Islands, and in doing so was the first professional botanist to outline the flora of King George Island. Only two vascular plants are known to grow on the island - Antarctic hair grass and Antarctic pearlwort. The flora is otherwise dominated by lichens and mosses. Ryszard Ochyra reports in his 1998 publication that there are 61 distinct species of moss found on the island, which is considered rich for the latitude. This makes King George Island "one of the most muscologically diverse areas in the Antarctic".

## Human activity
### Settlements

Human habitation of King George Island is limited to research stations belonging to Argentina, Brazil, Chile, China, South Korea, Peru, Poland, Russia, Uruguay, and the United States. Most of these stations are permanently staffed, carrying out research in areas as diverse as biology, ecology, geology, and palaeontology.
Base Presidente Eduardo Frei Montalva, the Chilean Station on the Fildes Peninsula, is operated as a permanent village with an airstrip (with large hangar and control tower along with other buildings), cafeterias for personnel of its several agencies there, a bank, a post office and comfortable ranch-style family homes with children. The Chinese Great Wall base features an indoor multipurpose room which serves as a full-size basketball court.
In 2004, a Russian Orthodox church, Trinity Church, was opened on the island near Russia's Bellingshausen Station. The church, one of the southernmost in the world and one of the few permanent structures in Antarctica, is permanently staffed by a priest. The first attempted murder in Antarctica occurred on the island in 2018 at Bellingshausen Station.
Point Thomas lighthouse at Arctowski Station is the most southerly lighthouse of the world.
NOAA runs Lenie Base, a seasonal research station for penguin studies on Admiralty Bay. This small station, dubbed Copacabana, operates in the Antarctic summer only, but is used as a survival hut in the winter.

### Tourism

In October 2013, American heavy metal band Metallica announced that it would perform a concert sponsored by The Coca-Cola Company at Carlini Station heliport. The concert took place on 8 December 2013.
A small amount of specialised tourist activity also takes place during summer, including an annual marathon, known as the Antarctic marathon.

## Climate

The Antarctic Peninsula and its nearby islands are considered to have the mildest living conditions in Antarctica. The island's climate is strongly influenced by the surrounding ocean. Under the Köppen system, it is one of the few locations in Antarctica classified as a tundra climate rather than an ice cap climate. Variation in temperatures are small, with the coldest month, July, averaging −6.5 °C (20.3 °F) and 1.5 °C (34.7 °F) in the warmest month. With only 591.3 hours of sunshine per year, the weather is often unsettled and cloudy throughout the year, with precipitation in the form of snow, rain, and drizzle occurring often. On average, 729 mm of precipitation falls per year.
