Pendulum Cove is a cove at the north-east side of Port Foster, Deception Island, in the South Shetland Islands of Antarctica. The name of the cove derives from the pendulum and magnetic observations made there by the British expedition under Henry Foster in 1829.
Base Aguirre Cerda , a Chilean metereological and volcanological research station in Pendulum Cove, opened in February 1955. It was destroyed by volcanic eruptions in 1967 and 1969. Since 2001 the ruins of the station have been designated a Historic Site or Monument (HSM 76), following a proposal by Chile to the Antarctic Treaty Consultative Meeting. [1]

Caleta Péndulo Refuge was an Antarctic refuge located on the coast of Pendulum Cove, in Port Foster, Deception Island in the South Shetland Islands. The refuge was inaugurated on November 19, 1947, by the Argentine Navy. It was the first refuge built by the Argentine Armed Forces in Antarctica. The construction took place during the second Argentine Antarctic campaign in the summer of 1947–1948 in support of the construction of Deception Station, which was inaugurated on January 25, 1948, on the opposite side of the island.
Years later, in 1955 Chile installed the Aguirre Cerda Base a few hundred meters from the refuge. A volcanic eruption on December 4, 1967, devastated the Chilean base and the Argentine refuge. The name of the cove, which was also given to the refuge, recalls the magnetic observations made with pendulums in the place by the British expedition headed by Henry Foster in 1828.[ citation needed ]
The cove forms part of an Antarctic Specially Protected Area (ASPA 140), comprising several separate sites on Deception Island, and designated as such primarily for its botanic and ecological values. [2]
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD.
Deception Island is in the South Shetland Islands close to the Antarctic Peninsula with a large and usually "safe" natural harbor, which is occasionally affected by the underlying active volcano. This island is the caldera of an active volcano, which seriously damaged local scientific stations in 1967 and 1969. The island previously held a whaling station. It is now a tourist destination with over 15,000 visitors per year. Two research stations are operated by Argentina and Spain during the summer season. While various countries have asserted sovereignty, it is still administered under the Antarctic Treaty System.
The South Shetland Islands are a group of Antarctic islands located in the Drake Passage with a total area of 3,687 km2 (1,424 sq mi). They lie about 120 kilometres north of the Antarctic Peninsula, and between 430 and 900 km southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes.
Livingston Island is an Antarctic island in the Southern Ocean, part of the South Shetlands Archipelago, a group of Antarctic islands north of the Antarctic Peninsula. It was the first land discovered south of 60° south latitude in 1819, a historic event that marked the end of a centuries-long pursuit of the mythical Terra Australis Incognita and the beginning of the exploration and utilization of real Antarctica. The name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s.
The Chilean Antarctic Territory, or Chilean Antarctica, is a part of West Antarctica and nearby islands claimed by Chile. It comprises the region south of 60°S latitude and between longitudes 53°W and 90°W, partially overlapping the Antarctic claims of Argentina and the United Kingdom. It constitutes the Antártica commune of Chile.
Yankee Harbour is a small inner harbour entered from Shopski Cove between Glacier Bluff and Spit Point, indenting the south-west side of Greenwich Island in the South Shetland Islands, Antarctica. It is 2.35 km (1.46 mi) long in west-south-west to east-north-east direction, and 1.6 km (0.99 mi) wide, and is bounded by Provadiya Hook to the south-west, Parvomay Neck to the north and east, and Kladara Beach to the south.
Telefon Bay is a small bay on the north-west coast of Port Foster, Deception Island, in the South Shetland Islands of Antarctica. It is surmounted by Telefon Ridge. The name appears on the chart of the French Antarctic Expedition under Charcot, 1908–10.
Port Foster is one of the safest harbours in Antarctica, located in Deception Island in the South Shetland Islands.
Risopatrón Base, also Luis Risopatrón Base, is a small Chilean Antarctic research base in the northwest of Robert Island in the South Shetland Islands, Antarctica situated on the isthmus linking Coppermine Peninsula to Alfatar Peninsula and bounded by Carlota Cove to the north and Coppermine Cove to the south. Established as a refuge in 1949 and opened as a base in 1954, the facility supports summer research in geology, geophysics and terrestrial biology.
Ardley Island is an island 1.9 kilometres (1 nmi) long, lying in Maxwell Bay close off the south-west end of King George Island, in the South Shetland Islands of Antarctica. It was charted as a peninsula in 1935 by Discovery Investigations personnel of the Discovery II and named for Lieutenant R.A.B. Ardley, Royal Naval Reserve, an officer on the ship in 1929–31 and 1931–33. Aerial photography has since shown that the feature is an island with Braillard Point being the headland forming the northeast end of Ardley Island. It has been designated an Antarctic Specially Protected Area because of the importance of its seabird colonies.
Collins Point is a small but prominent headland 1.4 km (0.87 mi) west-south-west of Fildes Point, on the south side of Port Foster, Deception Island, in the South Shetland Islands of Antarctica. It was charted by a British expedition under Foster, 1828–31. It was named by Lieutenant Commander D.N. Penfold, Royal Navy, following his survey of the island in 1948–49, for Rear Admiral Kenneth Collins of the Hydrographic Department of the Admiralty.
Stonethrow Ridge is a snow-covered ridge rising west of Fumarole Bay on Deception Island, in the South Shetland Islands of Antarctica. Vapour Col lies to the south of the ridge.
Mount Pond is a peak, 550 m (1,800 ft) in height, standing 2.8 km (1.7 mi) east-south-east of Pendulum Cove, on Deception Island in the South Shetland Islands of Antarctica. The name appears on an 1829 chart based upon survey work by the British expedition under Foster, 1828–31. It was probably named for John Pond, noted English astronomer and director of the Royal Observatory at Greenwich at that time.
Paradise Harbour is a wide embayment behind Lemaire Island and Bryde Island, indenting the west coast of Graham Land, Antarctica, between Duthiers Point and Leniz Point. The name was first applied by whalers operating in the vicinity and was in use by 1920.
Whalers Bay is a small bay entered between Fildes Point and Penfold Point at the east side of Port Foster, Deception Island, in the South Shetland Islands of Antarctica. The bay was so named by the French Antarctic Expedition, 1908–10, under Charcot, because of its use at that time by whalers.
Crater Lake is a volcanic crater, now filled with water, lying north-west of Mount Kirkwood on the south side of Deception Island, in the South Shetland Islands of Antarctica. The descriptive name was given by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959.
Ronald Hill is a rocky, ice-free hill, 105 m in height, standing north of Kroner Lake on Deception Island, in the South Shetland Islands of Antarctica. It was charted, photographed and named by Olaf Holtedahl of the Norwegian expedition 1927–28, after the floating factory SS Ronald, which belonged to the Hektor Whaling Company. and was anchored at Deception Island in 1911-12 and many later seasons.
South East Point is a point 1.9 km (1.2 mi) east-north-east of Fildes Point, marking the south-eastern point of Deception Island, in the South Shetland Islands of Antarctica. It was charted by a British expedition 1828–31, under Henry Foster. The name was proposed in 1949 by the Hydrographic Department of the Admiralty, following a survey of the island by Lieutenant Commander D.N. Penfold, Royal Navy, in 1948–49.
President Pedro Aguirre Cerda Station was a Chilean Antarctic base, located at Pendulum Cove in Deception Island in the South Shetland Islands, inaugurated in 1955. The same year, the Falkland Islands and Dependencies Aerial Survey Expedition was established at Deception Island to help the survey of the Antarctic Peninsula, operating aircraft from Hunting Aerosurveys Ltd.
The Deception Island incident took place in February 1953 when a group of British Royal Marines landed on Deception Island in Antarctica, took two Argentine sailors prisoner and destroyed an Argentine Navy base. A nearby Chilean base was also destroyed.
