Barrier Bay
Barrier Bay is an open bay in the Antarctic coastal angle formed by the coast and the western end of the West Ice Shelf. Charted by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–1937, and named by them Barrierevika (Barrier Bay). Barrier is an obsolete term for ice shelf An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The .... Bays of Princess Elizabeth Land Ingrid Christensen Coast {{PrincessElizabethLand-geo-stub ...

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] |
West Ice Shelf
The West Ice Shelf is a prominent ice shelf extending about in an east–west direction along the Leopold and Astrid Coast in East Antarctica between Barrier Bay and Posadowsky Bay, and up to 120 km northwards from the continental margin. Discovery and naming The ice shelf was discovered and named by the First German Antarctica Expedition, 1901–1903, under Dr Erich von Drygalski. The toponym describes the direction in which the German expedition first viewed the ice shelf. Their limited westward view became a prolonged one; on February 21, 1902, the ship became stuck in the pack ice, remaining imprisoned there until February 8, 1903. Important Bird Area A site on sea ice near the north-western margin of the shelf has been designated an Important Bird Area (IBA) by BirdLife International because it supports an emperor penguin colony.

Cartographers
Cartography (; from grc, χάρτης , "papyrus, sheet of paper, map"; and , "write") is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate characteristics of the mapped object that are not relevant to the map's purpose. This is the concern of generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements of the ...

Lars Christensen
Lars Christensen (6 April 1884 – 10 December 1965) was a Norwegian shipowner and whaling magnate. He was also a philanthropist with a keen interest in the exploration of Antarctica. Career Lars Christensen was born at Sandar in Vestfold, Norway. Born into a wealthy family, Christensen inherited his whaling fleet from his father, Christen Christensen. After completing middle school in 1899, he received training in Germany and at Newcastle followed by trade college in Kristiania (now Oslo). He started his career as a ship owner in 1906. He ventured into the whaling industry in 1909, and directed several companies, including Framnæs Mekaniske Værksted, AS Thor Dahl, AS Odd, AS Ørnen, AS Thorsholm and Bryde og Dahls Hvalfangstselskap. Christensen was Danish consul in Sandefjord from 1909. In 1910 Lars Christensen had married Ingrid Dahl (1891–1976), daughter of wholesale merchant and ship owner Thor Dahl (1862–1920). He would later assume control of large part of his fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of 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. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Bays Of Princess Elizabeth Land
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.
