Cain Nunatak
Cain Nunatak () is the westernmost of two isolated nunataks on the south side of Broad Valley, situated 3.37 km east-northeast of Kumata Hill on Trinity Peninsula, Antarctica. It is a volcanic feature and an inferred vent of the James Ross Island Volcanic Group. The name arose at the time of the Falkland Islands Dependencies Survey geological survey in 1960–61 and is in association with nearby Abel Nunatak, through the story of Cain and Abel In the biblical Book of Genesis, Cain ''Qayīn'', in pausa ''Qāyīn''; gr, Κάϊν ''Káïn''; ar, قابيل/قايين, Qābīl / Qāyīn and Abel ''Heḇel'', in pausa ''Hāḇel''; gr, Ἅβελ ''Hábel''; ar, هابيل, Hāb ....

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] |
Broad Valley
Broad Valley () is a descriptive name for the broad glacier-filled valley on the south side of Laclavere Plateau, Trinity Peninsula. The name was suggested by V.I.

Trinity Peninsula
Trinity Peninsula is the northernmost part of the Antarctic Peninsula. It extends northeastward for about 130 km (80 mi) to Cape Dubouzet from an imaginary line connecting Cape Kater on the north-west coast and Cape Longing on the south-east coast. Prime Head is the northernmost point of this peninsula. Some 20 kilometers southeast of Prime Head is Hope Bay with the year-round Argentinian Esperanza Base. History It was first sighted on 30 January 1820 by Edward Bransfield, Master, Royal Navy, immediately after his charting of the newly discovered South Shetland Islands nearby. In the century following the peninsula's discovery, chartmakers used various names (Trinity Land, Palmer Land, and Land of Louis Philippe) for this portion of it, each name having some historical merit. The recommended name derives from "Trinity Land", given by Bransfield during 1820 in likely recognition of the Corporation of Trinity House, Britain's historical maritime pilotage authority, altho ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

James Ross Island Volcanic Group
The James Ross Island Volcanic Group is a stratigraphic unit of Cenozoic age distributed on James Ross Island and Vega Island of the James Ross Island group, the Tabarin and Trinity peninsulas of Graham Land and surrounding islands in the Prince Gustav and Antarctic sounds. The volcanic group consists predominantly of alkali basalts with minor hawaiites, benmoreites and mugearites. They are interpreted to have been deposited by volcanic eruptions in an extensional back-arc setting after subduction had ceased along the western margin of the Antarctic Peninsula. K–Ar dating of these rocks suggest that they were erupted from about 7 million years ago up until about a few hundred thousand years ago. However, volcanic rocks as young as only a few thousand years old may exist on James Ross Island. Rocks of the James Ross Island Volcanic Group comprise Surtseyan tuff cones and Strombolian cinder cones, as well as lava deltas and overlying subaerial lava flows. The dominating fe ...

Falkland Islands Dependencies 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] |
Abel Nunatak
Abel Nunatak is the easternmost of two isolated nunataks on the south side of Broad Valley, Trinity Peninsula. It is a volcanic feature and an inferred vent of the James Ross Island Volcanic Group. The name arose at the time of the Falkland Islands Dependencies Survey (FIDS) geological survey in 1960–61 and is in association with nearby Cain Nunatak, after the biblical brothers Cain and Abel In the biblical Book of Genesis, Cain ''Qayīn'', in pausa ''Qāyīn''; gr, Κάϊν ''Káïn''; ar, قابيل/قايين, Qābīl / Qāyīn and Abel ''Heḇel'', in pausa ''Hāḇel''; gr, Ἅβελ ''Hábel''; ar, هابيل, Hāb ....

Cain And Abel
In the biblical Book of Genesis, Cain ''Qayīn'', in pausa ''Qāyīn''; gr, Κάϊν ''Káïn''; ar, قابيل/قايين, Qābīl / Qāyīn and Abel ''Heḇel'', in pausa ''Hāḇel''; gr, Ἅβελ ''Hábel''; ar, هابيل, Hābīl are the first two sons of Adam and Eve. Cain, the firstborn, was a farmer, and his brother Abel was a shepherd. The brothers made sacrifices to God, but God favored Abel's sacrifice instead of Cain's. Cain then murdered Abel, whereupon God punished Cain by condemning him to a life of wandering. Cain then dwelt in the land of Nod (), where he built a city and fathered the line of descendants beginning with Enoch. Genesis narrative The story of Cain's murder of Abel and its consequences is told in : Translation notes Origins Etymology Cain and Abel are traditional English renderings of the Hebrew names. It has been proposed that the etymology of their names may be a direct pun on the roles they take in the Genesis narrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
