Tern Nunatak ( 62°6′S58°20′W / 62.100°S 58.333°W / -62.100; -58.333 Coordinates: 62°6′S58°20′W / 62.100°S 58.333°W / -62.100; -58.333 ) is a nunatak lying just east of Lussich Cove, Admiralty Bay, on King George Island in the South Shetland Islands. Charted but not named by the French Antarctic Expedition, 1908–10, under Charcot. The name Tern Nunatak became established in local use at the Falkland Islands Dependencies Survey (FIDS) Admiralty Bay station in about 1949.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

Lussich Cove is a cove at the southeast side of Martel Inlet in Admiralty Bay, King George Island, in the South Shetland Islands. It was charted in 1909 by the Fourth French Antarctic Expedition under Jean-Baptiste Charcot, and named by him for Antonio Lussich of Montevideo, who was of assistance to the expedition.

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

Admiralty Bay is an irregular bay, 8 km (5 mi) wide at its entrance between Demay Point and Martins Head, indenting the southern coast of King George Island for 16 km (10 mi), in the South Shetland Islands of Antarctica. The name appears on a map of 1822 by Captain George Powell, a British sailor, and is now established in international usage. The Henryk Arctowski Polish Antarctic Station is situated on the bay, as is the Comandante Ferraz Brazilian Antarctic Base. It has been designated an Antarctic Specially Managed Area.

The Bay of Isles is a bay 9 miles (14 km) wide and receding 3 miles (5 km), lying between Cape Buller and Cape Wilson along the north coast of South Georgia. It was discovered in 1775 by a British expedition under James Cook and so named by him because numerous islands lie in the bay. Many of these islands are named after local birds, including:

Syrezol Rocks is a small group of rocks lying 1 mile (1.6 km) west of Martins Head at the east side of the entrance to Admiralty Bay, King George Island, in the South Shetland Islands. In 1908-10, the Fourth French Antarctic Expedition under Jean-Baptiste Charcot assigned the name "Cap Syrezol" to a feature between what is now Martins Head and Chabrier Rock. Since there is no distinctive point or cape in this position, the name has been applied to these rocks in order to preserve Charcot's naming in the area in which it was originally given.

Chabrier Rock is a rock which lies 0.5 miles (0.8 km) southwest of Vauréal Peak in the east side of the entrance to Admiralty Bay, King George Island, in the South Shetland Islands. It was charted and named in December 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot.

Telefon Rocks is a group of rocks 1.5 miles (2.4 km) south-southwest of Demay Point, and just east of Telefon Point, at the west side of the entrance to Admiralty Bay, King George Island, in the South Shetland Islands. Named after the Telefon, a vessel which went aground and was abandoned there in 1908.

Admiralen Peak, also variously known as Admiration Peak, Pico Puño, or Cerro Le Poing, is a peak, 1,000 feet (305 m) high, lying 0.7 miles (1.1 km) south-southwest of Crepin Point at the west side of Admiralty Bay on King George Island, in the South Shetland Islands. In 1908–10 the French Antarctic Expedition under Jean-Baptiste Charcot applied the name "Le Poing" to a feature in this area. It is not clear, however, which of four summits the name refers to and the name has been rejected. This peak was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for the Admiralen, the first modern floating factory ship, which first operated in Admiralty Bay in January 1906.

Aitkenhead Glacier glacier in Antarctica

Aitkenhead Glacier is a 10-mile (16 km) long glacier flowing east-southeast from the Detroit Plateau, Graham Land, into Prince Gustav Channel. It was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960–61), and named by the United Kingdom Antarctic Place-Names Committee for Neil Aitkenhead, a FIDS geologist at Hope Bay (1959–60).

Precious Peaks is a line of about three dark peaks at the northeast side of Martel Inlet, Admiralty Bay, on King George Island in the South Shetland Islands. Charted by the French Antarctic Expedition under Charcot, 1908-10. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Alan Precious of Falkland Islands Dependencies Survey (FIDS), meteorological observer at Hope Bay in 1954 and 1955, and leader at the Admiralty Bay station in 1957.

Baranowski Glacier is a glacier flowing east into Admiralty Bay, King George Island, northwest of Demay Point. It was named by the Polish Antarctic Expedition after Stanisław Baranowski (1935–78), Polish glaciologist who died on King George Island as a result of an accident at the Henryk Arctowski Polish Antarctic Station while a member of the 1977–78 expedition.

Noble Glacier is a small glacier lying just north of Flagstaff Glacier on the east side of Keller Peninsula, King George Island, in the South Shetland Islands. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Hugh M. Noble of Falkland Islands Dependencies Survey (FIDS), glaciologist at Admiralty Bay in 1957, who made detailed studies of the regime of Flagstaff and Stenhouse Glaciers.

Napier Rock is a rock lying 1.75 nautical miles (3.2 km) east-southeast of Point Thomas in Admiralty Bay, King George Island, in the South Shetland Islands. Charted by the French Antarctic Expedition under Charcot, 1908-10. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Ronald G. Napier (1925–1956) of Falkland Islands Dependencies Survey (FIDS), general assistant and handyman at the Signy Island station in 1955, and then leader at Admiralty Bay until he was drowned on March 24, 1956.

Crépin Point is a point which marks the west side of the entrance to Mackellar Inlet in Admiralty Bay, on King George Island, in the South Shetland Islands. It was charted and named Cap Crépin in 1909 by the French Antarctic Expedition, 1908–10 under Jean-Baptiste Charcot.

Krak Glacier is an outlet glacier of Kraków Dome at the head of Lussich Cove, Martel Inlet, Admiralty Bay, King George Island, in the South Shetland Islands.It was named by the Polish Antarctic Expedition, 1980, after the legendary prince Krak, founder of Kraków and killer of the Wawel Dragon.

Plaza Point is a point forming the south tip of Keller Peninsula, which separates Mackellar and Martel Inlets in the north part of Admiralty Bay, on King George Island, in the South Shetland Islands. Charted and named by the French Antarctic Expedition under Charcot, 1908-10. The name suggests the central position of the feature at the head of Admiralty Bay.

Goetel Glacier is a glacier flowing south between Ullmann Spur and the Precious Peaks into Martel Inlet, Admiralty Bay, on King George Island in the South Shetland Islands. It was named by the Polish Antarctic Expedition, 1980, after Professor Walery Goetel (1889–1972), a Polish geologist and conservationist.

Twin Pinnacles is a rock 20 m high marked by two summits, lying 0.1 nautical miles (0.2 km) northeast of Lions Rump at the west side of the entrance to King George Bay in the South Shetland Islands. Charted and named during 1937 by DI personnel on the Discovery II.

It was charted in December 1909 by the French Antarctic Expedition under J.B. Charcot, who presumably applied the name. It was first climbed in 1949 by Geoff Hattersley-Smith and Ken Pawson of the Falkland Islands Dependencies Survey.

Keller Peninsula is a high peninsula separating Mackellar Inlet and Martel Inlet in Admiralty Bay, on King George Island, in the South Shetland Islands of Antarctica. The name Keller was applied by the French Antarctic Expedition under Jean-Baptiste Charcot, who charted Admiralty Bay in December 1909.

Lange Glacier is a glacier flowing into the west side of Admiralty Bay close south of Admiralen Peak, King George Island, in the South Shetland Islands, Antarctica. It was charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and was named by the UK Antarctic Place-Names Committee in 1960 for Alexander Lange (1860–1922), a Norwegian pioneer of modern steam whaling in the South Shetland Islands in 1905–6, and commander of the Admiralen.
