Halley Research Station
Halley Research Station is a research facility in Antarctica on the Brunt Ice Shelf operated by the British Antarctic Survey (BAS). The base was established in 1956 to study the Earth's atmosphere. Measurements from Halley led to the discovery of the ozone hole in 1985. The current base is the sixth in a line of structures and includes design elements intended to overcome the challenge of building on a floating ice shelf without being buried and crushed by snow. , the base has been left unstaffed through winter since 2017, due to concerns over the propagation of an ice crack and how this might cut off the evacuation route in an emergency. The Halley Bay Important Bird Area with its emperor penguin colony lies in the vicinity of the base. History Halley Bay base was founded in 1956, for the International Geophysical Year of 1957–1958, by an expedition from the Royal Society. The bay where the expedition decided to set up their base was named after the astronomer Edmond Hall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Stations In Antarctica
Multiple governments have set up permanent research stations in Antarctica and these bases are widely distributed. Unlike the drifting ice stations set up in the Arctic, the current research stations of the Antarctic are constructed either on rocks or on ice that are (for practical purposes) fixed in place. Many of these stations are demographics of Antarctica, staffed throughout the year. Of the 56 signatories to the Antarctic Treaty System, Antarctic Treaty, a total of 55 countries (as of 2023) operate seasonal (summer) and year-round research stations on the continent. The number of people performing and supporting scientific research on the continent and nearby islands varies from approximately 4,800 during the summer to around 1,200 during the winter (June). In addition to these permanent stations, approximately Antarctic field camps, 30 field camps are established each summer to support specific projects.

Iceberg
An iceberg is a piece of fresh water ice more than long that has broken off a glacier or an ice shelf and is floating freely in open water. Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits". Much of an iceberg is below the water's surface, which led to the expression " tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard. Icebergs vary considerably in size and shape. Icebergs that calve from glaciers in Greenland are often irregularly shaped while Antarctic ice shelves often produce large tabular (table top) icebergs. The largest iceberg in recent history, named B-15, was measured at nearly in 2000. The largest iceberg on record was an Antarctic tabular iceberg measuring sighted west of Scott Island, in the South Pacific Ocean, by the USS ''Glacier'' on November 12, 1956. This iceberg was larger than Belgium. Etymology The word ''iceberg'' is a partial loan tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea. Much of the southern part of the sea is covered by a permanent, massive ice shelf field, the Filchner-Ronne Ice Shelf. The sea is contained within the two overlapping Antarctic territorial claims of Argentine Antarctica, the British Antarctic Territory, and also resides partially within the Antártica Chilena Province, Antarctic Chilean Territory. At its widest the sea is around across, and its area is around . Various ice shelves, including the Filchner-Ronne Ice Shelf, fringe the Weddell sea. Some of the ice shelves on the east side of the Antarctic Peninsula, which formerly covered roughly of the Weddell Sea, had completely disappeared by 2002. The Weddel ...

Ice Shelf
An ice shelf is a large platform of glacial ice floating on the ocean, fed by one or multiple tributary glaciers. Ice shelves form along coastlines where the ice thickness is insufficient to displace the more dense surrounding ocean water. The boundary between the ice shelf (floating) and grounded ice (resting on bedrock or sediment) is referred to as the grounding line; the boundary between the ice shelf and the open ocean (often covered by sea ice) is the ice front or calving front. Ice shelves are found in Antarctica and the Arctic (Greenland, Northern Canada, and the Russian Arctic), and can range in thickness from about . The world's largest ice shelves are the Ross Ice Shelf and the Filchner-Ronne Ice Shelf in Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. Typically, a shelf front will extend forward for years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neumayer Station III
Neumayer Station III, also known as Neumayer III after geophysicist Georg von Neumayer, is a German Antarctic research station of the Alfred-Wegener-Institut (AWI). It is located on the approximately thick Ekström Ice Shelf several kilometres south of Neumayer Station II.DB mobil, Ausgabe 11, 2008 The station's assembly kit was transported to its current position early in November 2007. It is moving with the shelf ice at about per year towards the open sea. After almost ten years of work on the project, beginning in October 1999, including conception, environmental impact assessment, planning and construction phases, regular operation of the station began on 20 February 2009. The station replaced the former Neumayer Station II and the Georg von Neumayer Station that preceded it. The expected lifespan of the station is 25 to 30 years and the entire project is estimated to cost €39 million. Construction phase The station was constructed above ground on a temporary two- ...
