South Georgia and the South Sandwich Islands (SGSSI) is a British overseas territory in the southern Atlantic Ocean.
It is a remote and inhospitable collection of islands, consisting of South Georgia and a chain of smaller islands known as the South Sandwich Islands. South Georgia is 165 kilometres (103 mi) long and 1 to 35 km (1 to 22 miles) wide and is by far the largest island in the territory. The South Sandwich Islands lie about 700 kilometres (430 mi) southeast of South Georgia.The total land area of the territory is 3,903 square kilometres (1,507 sq mi).Falkland Island is located about 1,300 km (810 mi) north-west from its nearest point.
There is no permanent population on the islands. The present inhabitants are the British Government Officer, Deputy Postmaster, scientists, and support staff from the British Antarctic Survey who maintain scientific bases at Bird Island and at the capital, King Edward Point, as well as museum staff at nearby Grytviken.
The United Kingdom claimed sovereignty over South Georgia in 1775 and the South Sandwich Islands in 1908. The territory of "South Georgia and the South Sandwich Islands" was formed in 1985; previously it had been governed as part of the Falkland Islands Dependencies. Argentina claimed South Georgia in 1927 and claimed the South Sandwich Islands in 1938.
Argentina maintained a naval station, Corbeta Uruguay, on Thule Island in the South Sandwich Islands from 1976 until 1982 when it was closed by the Royal Navy. The Argentine claim over South Georgia contributed to the 1982 Falklands War, during which Argentine forces briefly occupied the island. Argentina continues to claim sovereignty over South Georgia and the South Sandwich Islands.
South Sandwich Islands
Captain James Cook discovered the southern eight islands of the Sandwich Islands Group in 1775, although he lumped the southernmost three together, and their status as separate islands was not established until 1820 by Fabian Gottlieb von Bellingshausen.The northern three islands were discovered by Bellingshausen in 1819. The islands were tentatively named "Sandwich Land" by Cook, although he also commented that they might be a group of islands rather than a single body of land. The name was chosen in honour of John Montagu, 4th Earl of Sandwich, First Lord of the Admiralty. The word "South" was later added to distinguish them from the "Sandwich Islands", now known as the Hawaiian Islands.
Argentina claimed the South Sandwich Islands in 1938, and challenged British sovereignty in the Islands on several occasions. From 25 January 1955 to mid-1956, Argentina maintained the summer station Teniente Esquivel at Ferguson Bay on the southeastern coast of Thule Island. Argentina maintained a naval base (Corbeta Uruguay) from 1976 to 1982, in the lee (southern east coast) of the same island. Although the British discovered the presence of the Argentine base in 1976,protested and tried to resolve the issue by diplomatic means, no effort was made to remove them by force until after the Falklands War. The base was removed on 20 June 1982.
On 10 February 2008, a 6.5 magnitude earthquake had its epicentre 205 km (127 mi; 111 nmi) SSE of Bristol Island.On 30 June 2008 at 06:17:53 UTC, a 7.0 magnitude earthquake struck the region. Its epicentre was at 58.160S 21.893W, 283 km (176 mi; 153 nmi) ENE (73 degrees) of Bristol Island.The United States Geological Survey reported that a 7.3 magnitude earthquake had occurred at 10:04 EDT on 15 Jul 2013, 216 km (134 mi; 117 nmi) south-southeast of Bristol Island, South Sandwich Islands, at a depth of 31.3 km (19.4 mi). The epicentre was located 2230 km southeast of Stanley, Falkland Islands.
South Georgia and the South Sandwich Islands are a collection of islands in the South Atlantic Ocean. Most of the islands, rising steeply from the sea, are rugged and mountainous. At higher elevations, the islands are permanently covered with ice and snow.
South Georgia group
The South Georgia group lies about 1,390 kilometres (864 mi; 751 nmi) east-southeast of the Falkland Islands, at 54°–55°S, 36°–38°W. It comprises South Georgia Island itself,by far the largest island in the territory, and the islands that immediately surround it and some remote and isolated islets to the west and east-southeast. It has a total land area of 3,756 km2 (1,450 sq mi), including satellite islands but excluding the South Sandwich Islands which form a separate island group.
Islands within the South Georgia group
South Georgia Island lies at 54°15′S 36°45′WCoordinates: 54°15′S 36°45′W and has an area of 3,528 km2 (1,362 sq mi). It is mountainous and largely barren. Eleven peaks rise to over 2,000 metres (6,562 ft) high, their slopes furrowed with deep gorges filled with glaciers; the largest is Fortuna Glacier. The highest peak is Mount Paget in the Allardyce Range at 2,934 metres (9,626 ft).
Geologically, the island consists of gneiss and argillaceous schists with occasional tufts and other sedimentary layers from which fossils have been recovered.The island is a fragment of some greater land-mass now vanished and was probably a former extension of the Andean system.

- Black Rock 169 km (105 mi; 91 nmi) west-northwest of South Georgia Island and 16 km (9.9 mi; 8.6 nmi) southeast of the Shag Rocks
- Clerke Rocks 56 km (35 mi; 30 nmi) east-southeast of South Georgia Island
South Sandwich Islands
The South Sandwich Islands comprise 11 mostly volcanic islands excluding tiny satellite islands and offshore rocks, with some active volcanoes. They form an island arc running north-south in the region 56°18'–59°27'S, 26°23'–28°08'W, between about 350 miles (300 nmi; 560 km) and 500 miles (430 nmi; 800 km) southeast of South Georgia.
The northernmost of the South Sandwich Islands form the Traversay Islands and Candlemas Islands groups, while the southernmost make up Southern Thule. The three largest islands – Saunders, Montagu and Bristol – lie between the two. The Islands' highest point is Mount Belinda (1,370 m or 4,495 ft) on Montagu Island.
The South Sandwich Islands are uninhabited, though a permanently manned Argentine research station was located on Thule Island from 1976 to 1982 for details, see "History" section above. There are automatic weather stations on Thule (Morrell) Island and Zavodovski. To the northwest of Zavodovski Island is the Protector Shoal, a submarine volcano.
The climate is classified as polar, and the weather is highly variable and harsh; making a tundra (ET) in Köppen Climate Classification. Typical daily maximum temperatures in South Georgia at sea level are around 0 °C (32 °F) in winter (August) and 8 °C (46.4 °F) in summer (January). Winter minimum temperatures are typically about −5 °C (23 °F) and rarely dip below −10 °C (14 °F). Annual precipitation in South Georgia is about 1,500 mm (59.1 in), much of which falls as sleet or snow, which is possible in any month. Inland, the snow line in summer is at an altitude of about 300 m (984 ft).
Westerly winds blow throughout the year interspersed with periods of calm—indeed, in 1963, 25% of winds were in the calm category at King Edward point, and the mean wind speed of around 8 knots (9.2 mph; 15 km/h) is around half that of the Falkland Islands. This gives the eastern side of South Georgia a more pleasant climate than the exposed western side. The prevailing weather conditions generally make the islands difficult to approach by ship, though the north coast of South Georgia has several large bays which provide good anchorage.
Sunshine, as with many South Atlantic Islands, is low, at a maximum of just 21.5%. This amounts to around 1,000 hours of sunshine annually. The local topography, however, also contributes significantly to the low insolation. A study published during the early 1960s indicated that sunshine recording instruments remained significantly obscured throughout the year and entirely obscured during June. It was estimated that the theoretical sunshine exposure minus obstructions would be around 14% at Bird Island and 35% at King Edward Point – or, in hourly terms, ranging from around 650 hours in the west to 1,500 hours in the east. This illustrates the effect the Allardyce range has in breaking up cloud cover.
Mountain winds blow straight up the western side and straight down the eastern side of the mountains and become much warmer and drier due to the Föhn effect; this produces the most pleasant conditions when temperatures can occasionally rise over 20 °C (68 °F) on summer days. The highest recorded temperature was 28.8 °C (83.8 °F) at Grytviken and 26.3 °C (79.3 °F) at nearby King Edward point, both on the sheltered East side of the Islands. Conversely, the highest recorded temperature at Bird Island on the windward Western side is a mere 14.5 °C (58.1 °F). As one might expect, the sheltered eastern side can also record lower winter temperatures—the absolute minimum for Grytviken being −19.4 °C (−2.9 °F), King Edward Point −18.9 °C (−2.0 °F), but Bird Island just −11.4 °C (11.5 °F).
The seas surrounding South Georgia are cold throughout the year due to the proximity of the Antarctic Current. They usually remain free of pack ice in winter, though thin ice may form in sheltered bays, and icebergs are common.Sea temperatures drop to 0 °C (32 °F) in late August and rise to around 4 °C (39.2 °F) only in early April.
The South Sandwich Islands are much colder than South Georgia, being farther south and more exposed to cold outbreaks from the Antarctic continent. They are also surrounded by sea ice from the middle of May to late November (even longer at their southern end).Recorded temperature extremes at South Thule Island have ranged from −29.8 to 17.7 °C (−21.6 to 63.9 °F).
Executive power is vested in the Monarch of the United Kingdom and is exercised by the Commissioner, a post held by the Governor of the Falkland Islands. The current Commissioner is Colin Roberts, who became Commissioner on 29 April 2014. A Chief Executive Officer (Martin Collins) deals with policy matters and is Director of SGSSI Fisheries, responsible for the allocation of fishing licences.
An Executive Officer (Richard McKee) deals with administrative matters relating to the territory. There is also an Environmental Officer (Jennifer Lee) and a Marine & Fisheries Officer (Katherine Ross). The Financial Secretary and Attorney General of the territory are appointed ex officio similar appointments in the Falkland Islands' Government.
As there are no permanent inhabitants on the islands, there is no legislative council and no elections are held. The UK Foreign Office manages the foreign relations of the territory. Since 1982 the territory celebrates Liberation Day on 14 June.
The constitution of the territory adopted 3 October 1985, the manner in which its government is directed and the availability of judicial review were discussed in a series of litigations between 2001 and 2005 ex parte Quark Fishing Limited UKHL 57.Although its government is entirely directed by the UK Foreign Office, it was held that its decisions under that direction could not be challenged as if they were in law decisions of a UK government department;thus the European Convention on Human Rights did not apply.
As there are no native inhabitants, economic activity in South Georgia and the South Sandwich Islands is limited. The territory has revenues of £4.5 million, 80% of which is derived from fishing licences.Other sources of revenue are the sale of postage stamps and coins, tourism and customs and harbour dues.
Fishing takes place around South Georgia and in adjacent waters in some months of the year, with fishing licences sold by the territory for Patagonian toothfish, cod icefish and krill. Fishing licences bring in millions of pounds a year, most of which is spent on fishery protection and research. All fisheries are regulated and managed in accordance with the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) system.
In 2001 the South Georgia government was cited by the Marine Stewardship Council for its sustainable Patagonian toothfish fishery, certifying that South Georgia met the MSC's environmental standards. The certificate places limits on the timing and quantity of Patagonian toothfish that may be caught.
Tourism has become a larger source of income in recent years, with many cruise ships and sailing yachts visiting the area,the only way to visit South Georgia is by sea; there are no airstrips on the Islands. The territory gains income from landing charges and the sale of souvenirs. Cruise ships often combine a Grytviken visit with a trip to the Antarctic Peninsula.
Charter yacht visits usually begin in the Falkland Islands, last between four and six weeks, and enable guests to visit remote harbours of South Georgia and the South Sandwich Islands. Sailing vessels are now required to anchor out and can no longer tie up to the old whaling piers on shore. One exception to this is the recently upgraded/repaired yacht berth at Grytviken. All other jetties at former whaling stations lie inside a 200 m (656 ft) exclusion zone; and berthing, or putting ropes ashore, at these is forbidden. Yachts visiting South Georgia are normally expected to report to the Government Officer at King Edward Point before moving round the island.
The island has featured in the Warren Miller video Storm.
A large source of income from abroad also comes from the issue of South Georgia and the South Sandwich Islands postage stamps which are produced in the UK.
A reasonable issue policy,few sets of stamps are issued each year along with attractive subject matter especially whales, makes them popular with topical stamp collectors.
There are only four genuine first day cover sets from 16 March 1982 in existence. They were stamped at the South Georgia Post Office; all those in circulation were stamped elsewhere and sent out, but the only genuine ones were kept at the Post Office on South Georgia. These four sets were removed during the Falklands War by a member of staff of the British Antarctic Survey in the few moments the Argentinians allowed them to gather their belongings. Everything else was burnt, but these four sets were saved and brought to the UK by Robert Headland, BAS.
The pound sterling is the official currency of the islands, and the same notes and coins are used as in the United Kingdom. For more information on British currency in the wider region, see Pound sterling in the South Atlantic and the Antarctic.
The parts of the islands that are not permanently covered in snow or ice are part of the Scotia Sea Islands tundra ecoregion. In total there are 26 species of vascular plant native to South Georgia; six species of grass, four rushes, a single sedge, six ferns, one clubmoss and nine small forbs. There are also about 125 species of moss, 85 of liverworts and 150 lichens, as well as about 50 species of macrofungi.A number of introduced species have become naturalised; many of these were introduced by whalers in cattle fodder, and some are considered invasive.There are no trees or shrubs on the islands.
The largest plant is the tussock grass Poa flabellata. This grows mostly on raised beaches and steep slopes near the shore and may reach 2 m (7 ft). Other grasses include the tufted fescue (Festuca contracta), the Alpine cat's-tail (Phleum alpinum) and Antarctic hair-grass (Deschampsia antarctica), and one of the commonest flowering plants is the greater burnet (Acaena magellanica).
South Georgia supports many sea birds, including albatross, a large colony of king penguins, Macaroni penguins and penguins of various other species, along with petrels, prions, shags, skuas, gulls and terns. Birds unique to the archipelago are the South Georgia shag, South Georgia pipit, and the South Georgia pintail. Both South Georgia and the South Sandwich Islands have been identified as Important Bird Areas (IBA) by BirdLife International.
Seals frequent the islands, and whales may be seen in the surrounding waters. There are no native land mammals, though reindeer, brown rats and mice were introduced to South Georgia through the activities of man.
Rats, brought to the island as stowaways on sealing and whaling ships in the late 18th century,have caused much damage to native wildlife, destroying tens of millions of ground-nesting birds’ eggs and chicks. While previously the island's glaciers formed a natural barrier to the spread of rats, these glaciers are now slowly melting as the climate warms.In 2011, scientists instituted a four-year programme to entirely eradicate the rats and mice, in what would be by far the largest rodent eradication attempt in the world to date.
The project was led by zoologist Anthony Martin of The University of Dundee who stated, This is a man-induced problem and it's about time that man put right earlier errors.In July 2013, the success of the main phase of the extermination of the rats, which took place in May that year, was announced. 180 tonnes of rat poison, brodifacoum, were dropped over 70% of the island, in what was the world's largest ever operation of this kind.
Another 95t of rat poison was planned to be dropped by three helicopters in January 2015.In June 2015 the eradication programme concluded, apparently successfully, with the island believed "very likely" to be rat free. Monitoring will continue for a further two or three years.
Reindeer were introduced to South Georgia in 1911 by Norwegian whalers for meat and for sport hunting. In February 2011, the authorities announced that due to the reindeer's detrimental effect on native species and the threat of their spreading to presently pristine areas, a complete cull would take place, leading to the eradication of reindeer from the island.The eradication began in 2013 with 3,500 reindeer killed. Nearly all the rest were killed in early 2014, with the last about 50 cleared in the 2014/15 southern summer.
The seas around South Georgia have a high level of biodiversity. In a recent study (2009–2011), South Georgia has been discovered to contain one of the highest levels of biodiversity among all the ecosystems on Earth.In respect to species, marine inhabitants endemic to this ecosystem outnumber and in respect to biodiversity, surpass well-known regions such as the Galápagos or Ecuador.
The marine ecosystem is thought to be vulnerable because its low temperatures mean that it can repair itself only very slowly. On 23 February 2012, to protect marine biodiversity, the territory's government created the South Georgia and the South Sandwich Islands Marine Protected Area – comprising 1.07 million km2.
After the Falklands War in 1982, a full-time British military presence was maintained at King Edward Point on South Georgia. This was scaled down during the 1990s until the last detachment left South Georgia in March 2001, after a new station had been built and occupied by the British Antarctic Survey.
The main British military facility in the region is at RAF Mount Pleasant and the adjacent Mare Harbour naval base on East Falkland. A handful of British naval vessels patrol the region, visiting South Georgia a few times each year and sometimes deploying small infantry patrols. Flights by RAF C-130 Hercules and Vickers VC10 replaced by Voyager aircraft also occasionally patrol the territory.
A Royal Navy destroyer or frigate and a Royal Fleet Auxiliary vessel carry out the Atlantic Patrol Task (South) mission in the surrounding area.
HMS Endurance, the Royal Navy ice-patrol ship, operated in the South Georgia area during part of most southern summer seasons until her near loss due to flooding in 2008. She carried out hydrological and mapping work as well as assisting with scientific fieldwork for the British Antarctic Survey, film and photographic units, and youth expedition group BSES Expeditions.
While the final decision on the fate of Endurance was pending, the Royal Navy chartered a Norwegian icebreaker, renamed HMS Protector, to act as replacement for three years.In September 2013 the British Ministry of Defence purchased the ship outright.It was announced on 7 October 2013 that Endurance will be sold for scrap.
