Siple Dome
Siple Dome () is an ice dome approximately 100 km wide and 100 km long, located 130 km east of Siple Coast in Antarctica. Charles Bentley and Robert Thomas established a "strain rosette" on this feature to determine ice movement in 1973–74. They referred to the feature as Siple Dome because of its proximity to Siple Coast. Siple Dome ice core The Siple Dome ice core project (79.468° S 112.086° W) was conducted by the United States National Science Foundation. The deepest ice was recovered in 1999 from 974 m, with an age of 97,600 years. It is best known for the poorly-explained steps in water isotopes during the deglacial, which are unique to this core and may indicate a rapid decrease in the surface elevation of the adjoining ice streams during the deglacial and a record of atmospheric carbon dioxide. The Chief Scientist was Kendrick Taylor. Radar surveys of internal ice structure In the 1990s a team from the University of Washington and St Olaf College su ...

Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of (including Eights Coast, immediately east of Marie Byrd Land). In 1939, United States President Fra ...

The Gathering (Testament Album)
''The Gathering'' is the eighth studio album by American thrash metal band Testament, released on June 8, 1999. It was the first release the band had done with Spitfire Records. Co-produced by band members, Chuck Billy and Eric Peterson, this was the first album featuring new musicians Steve DiGiorgio on bass guitar and Dave Lombardo on drums. Billy, Peterson and Lombardo, along with longtime Testament collaborator Del James, are also given composer credits on the album. It would also be the only Testament album for 23 years to feature Lombardo, who left the band right before the tour for ''The Gathering'' started and he would rejoin in 2022. ''The Gathering'' continued Testament's transition into death metal which began on their previous album '' Demonic'', but it also brought back their thrash-oriented sound. As a result, this album has been seen as a return-to-form for the band. Overview ''The Gathering'' featured eleven tracks when it was released, drawing critic and fan a ...

Antarctic Field Camps
Many Antarctic research stations support satellite field camps which are, in general, seasonal camps. The type of field camp can vary – some are permanent structures used during the annual Antarctic summer, whereas others are little more than tents used to support short term activities. Field camps are used for many things, from logistics (Sky Blu) to dedicated scientific research ( WAIS Divide Field Camp). List of field camps See also *Research stations in Antarctica * Demographics of Antarctica *List of Antarctic expeditions This list of Antarctic expeditions is a chronological list of expeditions involving Antarctica.

WAIS Divide
The WAIS Divide is the ice flow divide on the West Antarctic Ice Sheet (WAIS) which is a linear boundary that separates the region where the ice flows to the Ross Sea, from the region where the ice flows to the Weddell Sea. It is similar to a continental hydrographic divide. Ice core project The WAIS Divide ice core project (West Antarctic Ice Sheet Divide ice core project) investigated past climate changes, ice sheet dynamics and cryobiology. The project was completed by the United States Antarctic Program (USAP) and was funded by the National Science Foundation (NSF). The focus of the project was to develop records spanning the last ~ 80,000 years of the concentration of greenhouse gases in the atmosphere and Antarctic climate, and to do this with the highest possible time resolution. The project is best known for producing records of atmospheric carbon dioxide and methane with high time resolution and dating accuracy. This was accomplished by collecting and analyzing an ice ...

Nunavut
Nunavut ( , ; iu, ᓄᓇᕗᑦ , ; ) is the largest and northernmost territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the '' Nunavut Act'' and the '' Nunavut Land Claims Agreement Act'', which provided this territory to the Inuit for independent government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the first major change to Canada's political map in half a century since the province of Newfoundland was admitted in 1949. Nunavut comprises a major portion of Northern Canada and most of the Arctic Archipelago. Its vast territory makes it the fifth-largest country subdivision in the world, as well as North America's second-largest (after Greenland). The capital Iqaluit (formerly Frobisher Bay), on Baffin Island in the east, was chosen by a capital plebiscite in 1995. Other major communities include the regional centres of Rankin Inlet and Cambridge Bay. Nunavut also includes Ellesme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctic Plateau
The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica which extends over a diameter of about , and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about . Exploration This plateau was first sighted in 1903 during the ''Discovery'' Expedition to the Antarctic, which was led by Robert Falcon Scott. Ernest Shackleton became the first to cross parts of this plateau in 1909 during his ''Nimrod'' Expedition, which turned back in bad weather when it had reached a point just from the South Pole. Shackleton named this plateau the King Edward VII Plateau in honour of the king of the United Kingdom. In December 1911, while returning from the first journey to the South Pole, the Norwegian explorer Roald Amundsen decided to name this plateau the King Haakon VII Plateau in honour of the newly elected king of Norway.

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Cap Climate
An ice cap climate is a polar climate where no mean monthly temperature exceeds . The climate covers areas in or near the high latitudes (65° latitude) to polar regions (70–90° north and south latitude), such as Antarctica, some of the northernmost islands of Canada and Russia, Greenland, along with some regions and islands of Norway's Svalbard Archipelago that have vast deserts of snow and ice. Areas with ice cap climates are normally covered by a permanent layer of ice and have no vegetation. There is limited animal life in most ice cap climates, usually found near the oceanic margins. Although ice cap climates are inhospitable to human life, there are some small research stations scattered in Antarctica and interior Greenland. Description Under the Köppen climate classification, the ice cap climate is denoted as ''EF''. Ice caps are defined as a climate with no months above . Such areas are found around the north and south pole, and on the top of many high mountains. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
