Oceana Nunatak
Oceana Nunatak () is one of the Seal Nunataks, lying at the northwest corner of Robertson Island, off the east coast of Antarctic Peninsula. Discovered by a Norwegian whaling expedition under C.A. Larsen Carl Anton Larsen (7 August 1860 – 8 December 1924) was a Norway, Norwegian-born Whaling, whaler and Antarctic explorer who made important contributions to the exploration of Antarctica, the most significant being the first discovery of fos ... in December 1893, and named after the Oceana Co. of Hamburg, a sponsor of the expedition.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Seal Nunataks
The Seal Nunataks are a group of 16 islands called nunataks emerging from the Larsen Ice Shelf east of Graham Land, Antarctic Peninsula. The Seal Nunataks have been described as separate volcanic vents of ages ranging from Miocene to Pleistocene. There are unconfirmed reports of Holocene volcanic activity. Geography and geomorphology The Seal Nunataks are part of Graham Land and were embedded within the Larsen Ice Shelf until its northern margin collapsed between 1986 and 1996, rising from about below sea level. They were discovered by the Norwegian Carl Anton Larsen in December 1893, who also identified them as volcanoes and named them ''Seal Islands''. The Argentina Base Aérea Teniente Benjamín Matienzo is located in the Seal Nunataks. The Seal Nunataks are part of a volcanic province in West Antarctica which extends over the Antarctic Peninsula, Marie Byrd Land and Ross Island. In the Antarctic Peninsula, Alexander Island, James Ross Island and the Seal Nunataks f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robertson Island
Robertson Island is an ice-covered island, long in a northwest-southeast direction and wide, lying at the east end of the Seal Nunataks off the east coast of the Antarctic Peninsula. Captain Carl Anton Larsen discovered Robertson Island from the ''Jason'' on 9 December 1893. Curious to find out if the volcano was active he skied to the top from the north side of the island, later naming it Mt. Christensen after his longtime partner and majority owner of the ''Jason'', Christen Christensen. Larsen named Robertson Island for William Robertson, co-owner of the Hamburg-based company Woltereck and Robertson. San Roque Refuge San Roque Refuge () was an Argentine Antarctic refuge located on Robertson Island at the east end of the Foca nunataks off the Nordenskjöld coast east of the Antarctic Peninsula. The shelter was opened on 1 October 1956, and was administered by the Argentine Army. The refuge had been occupied and used in various operations and currently is inactive. It is ...

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...

Nunataks Of Graham Land
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. 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. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ...
