Rhyolite Head
Rhyolite Head () is the headland between Cardozo Cove and Goulden Cove in Ezcurra Inlet, Admiralty Bay, King George Island. It was so named following geological work by British Antarctic Survey (BAS), 1975–76, because the feature largely results from the indurating effects of a rhyolite intrusion, a rare lithology in the South Shetland Islands The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 195 ....

Headland
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardozo Cove
Cardozo Cove is the northern of two coves at the head of Ezcurra Inlet, Admiralty Bay, on King George Island in the South Shetland Islands. It was probably named by the French Antarctic Expedition under Jean-Baptiste Charcot, who charted Admiralty Bay in December 1909.

Goulden Cove
Goulden Cove () is the southern of two coves at the head of Ezcurra Inlet, Admiralty Bay, on King George Island, in the South Shetland Islands. It was probably named by the French Antarctic Expedition under Jean-Baptiste Charcot, who surveyed Admiralty Bay in December 1909. Located at its head is an icefall called Doctors Icefall.

Ezcurra Inlet
Ezcurra Inlet () is an inlet forming the western arm of Admiralty Bay (South Shetland Islands), Admiralty Bay, King George Island (South Shetland Islands), King George Island, in the South Shetland Islands. It was charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named "Fiord Ezcurra" after Pedro de Ezcurra, an Argentine politician and Minister of Agriculture in 1908, who assisted the French expedition. Shortly after this area was charted, a mariner's guide to the region stated that "the western fijord does not appear to offer good anchorage, as it is too exposed to squalls." Additionally, it was said to have not been used by whalers who frequented the waters due to the ice floes that blocked access to Admiralty Bay. Hervé Cove indents the south side of the inlet, southwest of Point Thomas. It was charted by the French Antarctic Expedition under Charcot, and named by him for a member of the expedition. Italia Valley lies east-northeast. See ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Admiralty Bay (South Shetland Islands)
Admiralty Bay is an irregular bay, wide at its entrance between Demay Point and Martins Head, indenting the southern coast of King George Island for , 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 (ASMA 1). Description The bay has three fjords: Martel, Mackellar, and Ezcurra. A mariner's guide to the region pronounced the bay to have the best anchorage of any in the South Shetlands, "being well-sheltered all around and having moderate depths over a bottom of good, stiff clay. Ice from the glaciers is frequently troublesome." Chilean scientists have claimed that Amerinds visited the area, due to stone artifacts recovered from bottom-sampling operations in the bay. how ...

King George Island (Antarctica)
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 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. History 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 ho ...

British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office. At the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between 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. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
