Helland Glacier
Helland Glacier () is a glacier long flowing southwest from Mount Paget to Rocky Bay (South Georgia), Rocky Bay, on the south side of South Georgia Island, South Georgia. It was mapped by Olaf Holtedahl during his visit to South Georgia in 1927–28, and named by him for Amund Helland, a Norwegian mining geologist and glaciologist.

South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken.

Rocky Bay (South Georgia)
Rocky Bay is a small bay situated immediately north of Ducloz Head along the south coast of South Georgia. Numerous rocks lie in the bay and at its entrance, such as Skontorp Rock. The presence of this bay seems to have been first noted in 1819 by Admiral Thaddeus Bellingshausen Fabian Gottlieb Thaddeus von Bellingshausen (russian: Фадде́й Фадде́евич Беллинсга́узен, translit=Faddéy Faddéevich Bellinsgáuzen; – ) was a Russian Empire, Russian naval officer, cartographer and explorer ... who roughly charted a small inlet in this approximate position. The name was in use prior to 1930 and was probably applied by sealers and whalers working in the area. Bays of South Georgia {{SouthGeorgia-geo-stub ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Mount Paget
Mount Paget is a summit of Allardyce Range on the South Atlantic/Antarctic island of South Georgia. It is the highest peak on the island, and also the highest peak in any territory under the sovereignty of the United Kingdom (excluding the British Antarctic Territory, which has no permanent population and where British sovereignty is unrecognized by most countries, where Mount Hope is the highest peak), more than twice the height of Ben Nevis, the highest mountain on the island of Great Britain. It is a saddle-shaped mountain, marking the highest point of the Allardyce Range in the central part of South Georgia. This feature was known to early sealers and whalers at South Georgia, and the name has long been established through general usage. It is clearly visible from Grytviken and King Edward Point King Edward Point (also known as KEP) is a permanent British Antarctic Survey research station on South Georgia island and is the capital of the British Overseas Territory of So ...

Olaf Holtedahl
Prof Olaf Holtedahl ForMemRS FRSE (24 June 1885 – 26 August 1975) was a Norwegian geologist (Dr.philos., 1913). He became a senior lecturer at the University of Oslo in 1914, and was Professor of Geology there from 1920 to 1956. Career Olaf Holtedahl was born in Kristiania (modern-day Oslo), Norway, the son of Arne H. Holtedahl, superintendent of pauper administration, and his wife, Mathilde Madsen. Around 1903 he did his obligatory military service at Gardermoen, just north of Oslo, and here met Captain Gunnar Isachsen who greatly influenced him, and first inspired his interest in polar regions. In 1909, Isachsen invited Holtedahl to join him in explorations of Spitsbergen as official geologist of the group. He studied Geology at the University of Oslo, graduating in 1909 and receiving a doctorate in 1913. Staying in the university as staff he received his professorship in 1920. Holtedahl was among the last of a generation of geologists that mastered the subject in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amund Helland
Amund Helland (11 October 1846 – 15 November 1918) was a Norwegian geologist, politician and non-fiction writer. He is particularly known for his works on glacial erosion and the role of glaciers in the formation of valleys, fjords and lakes. He is also known for starting the series '' Norges Land og Folk'', published in 20 volumes from 1885 to 1921. Personal life Helland was born in Bergen as the son of merchant Hans Helland (1817–1859) and Karen Marie Folkedal. He had six siblings. When his father died in 1859, his mother earned to the family's living by running a pension. He died in Kristiania in 1918. Career Helland was a student from 1864, and graduated as cand.min. in 1868. In his early career he made excursions to Greenland, Iceland and other European countries. In his first work, the monography ''Ertsforekomster i Søndhordland og Forekomster af Kise i visse Skifere i Norge'' from 1871, he claimed unconventional views which were not appreciated by elder collea ...

List Of Glaciers In The Antarctic
There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System).

Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...
