Donald Nunatak
Donald Nunatak () is a nunatak north of Gray Nunatak in the Seal Nunataks group, off the east coast of the Antarctic Peninsula. It was charted in 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld, and named by him for Dr. C.W. Donald, ship's doctor and naturalist on the ''Active'', one of the vessels of the Dundee Whaling Expedition The Dundee Whaling Expedition (1892–1893) was a commercial voyage from Scotland to Antarctica.

Nunatak
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Nunatak
Gray Nunatak () is a nunatak which lies west of Arctowski Nunatak in the Seal Nunataks group, off the east coast of the Antarctic Peninsula. It was first charted by the Swedish Antarctic Expedition under Otto Nordenskiöld during a sledge journey in 1902, and named by him probably for Captain David Gray, a whaling skipper of Peterhead, Scotland. Gray had planned an expedition to the Weddell Sea The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha ... in 1891 but the plan was abandoned due to a lack of funds. References Nunataks of Graham Land Oscar II Coast {{OscarIICoast-geo-stub ...

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] |
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 ...

Swedish Antarctic Expedition
The Swedish Antarctic Expedition of 1901–1903 was a scientific expedition led by Otto Nordenskjöld and Carl Anton Larsen. It was the first Swedish endeavour to Antarctica in the Heroic Age of Antarctic Exploration. Background Otto Nordenskjöld, a Swedish geologist and geographer, organized and led a scientific expedition of the Antarctic Peninsula. The expedition's overall command was placed under the Norwegian Carl Anton Larsen, an experienced Antarctic explorer who served as captain of , and who had previously commanded a whaling reconnaissance mission in 1892–1893. Seven other scientists, including archaeologist Johan Gunnar Andersson, botanist Carl Skottsberg, and zoologist Axel Ohlin, along with 16 officers and men joined them on the voyage. On 16 October 1901, the ''Antarctic'' left the Port of Gothenburg. Events Despite its end and the great hardships endured, the expedition would be considered a scientific success, with the parties having explored muc ...

Otto Nordenskiöld
Otto is a masculine German given name and a surname. It originates as an Old High German short form (variants ''Audo'', ''Odo'', ''Udo'') of Germanic names beginning in ''aud-'', an element meaning "wealth, prosperity". The name is recorded from the 7th century ( Odo, son of Uro, courtier of Sigebert III). It was the name of three 10th-century German kings, the first of whom was Otto I the Great, the first Holy Roman Emperor, founder of the Ottonian dynasty. The Gothic form of the prefix was ''auda-'' (as in e.g. '' Audaþius''), the Anglo-Saxon form was ''ead-'' (as in e.g. ''Eadmund''), and the Old Norse form was '' auð-''. The given name Otis arose from an English surname, which was in turn derived from ''Ode'', a variant form of ''Odo, Otto''. Due to Otto von Bismarck, the given name ''Otto'' was strongly associated with the German Empire in the later 19th century. It was comparatively frequently given in the United States (presumably in German American families) during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dundee Whaling Expedition
The Dundee Whaling Expedition (1892–1893) was a commercial voyage from Scotland to Antarctica. Whaling in the Arctic was in decline from overfishing. The merchants of Dundee decided to equip a fleet to sail all the way to the Weddell Sea in search of right whales. Antarctic whaling was mostly done from shore-based stations. On 6 September 1892, four steam-powered whaling ships, the , , '' Diana'' and ''Polar Star'', set off.Voyage of the Balaena Glasgow Digital Library, retrieved 3 December 2013 In the end they found no whales they could harvest as the s of the Antarctic were too powerful to be captured. However, the expedition managed to make a profit by collecting numerous seal pelts. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
