Atka Bay
Atka Iceport, also known as Atka Bay, is an iceport about long and wide, marking a more-or-less permanent indentation in the front of the Ekstrom Ice Shelf on the coast of Queen Maud Land. Discovery and naming Atka Iceport was mapped in detail by Norwegian cartographers from surveys and air photographs taken by the Norwegian-British-Swedish Antarctic Expedition (1949-1952), led by John Schjelderup Giæver. It was named by personnel of the USS ''Atka'', under U.S. Navy Commander Glen Jacobsen, which moored here in February 1955 while investigating possible base sites for International Geophysical Year operations. Station Atka Bay is the site of Germany's Neumayer-Station III. Important Bird Area A 425 ha tract of sea ice in the bay has been identified as an Important Bird Area by BirdLife International because it supports a breeding colony of about 12,000 emperor penguins.

2007 Ps-abschied Hg
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arabs developed the digit fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Penguin Colonies
Penguins ( order Sphenisciformes , family Spheniscidae ) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the little blue penguin (''Eudyptula minor''), also known as the fairy penguin, which stands around tall and weighs . Today, larger penguins generally inhabit colder regions, and smaller penguins in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Important Bird Areas Of Antarctica
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So on this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world actually is and how the world would have bee ...

Bay Of Whales
The Bay of Whales was a natural ice harbour, or iceport, indenting the front of the Ross Ice Shelf just north of Roosevelt Island, Antarctica. It is the southernmost point of open ocean not only of the Ross Sea, but worldwide. The Ross Sea extends much further south – as far as the Gould Coast, some from the South Pole – but most of that area is covered by the Ross Ice Shelf rather than open sea. Discovery and naming Ernest Shackleton named the feature on January 24, 1908, during the Nimrod Expedition, because of the large number of whales seen near this location. History During his quest for the South Pole, Norwegian explorer Roald Amundsen established a temporary base, which he named Framheim, at the Bay of Whales. The base was used between January 1911February 1912, and was named after Amundsen's ship ''Fram''. The Bay of Whales has also served as a logistical support base for several other important Antarctic expeditions, including: * 1928–1930: Richard Evelyn ...

Norsel Iceport
Norsel Iceport (), also known as Norselbukta or Bukhta Nursel, is a small iceport in the front of the Quar Ice Shelf, along the coast of Queen Maud Land. Discovery and naming This feature was named by the Norwegian–British–Swedish Antarctic Expedition (NBSAE), 1949–52, which used it to moor and unload the expedition ship . The low ice front permitted easy access onto Quar Ice Shelf, where the NBSAE established Maudheim Station about 1 nautical mile south of the iceport.

Godel Iceport
Godel Iceport is an iceport about wide, which marks a more-or-less permanent indentation in the seaward front of the extensive ice shelf fringing the coast of Queen Maud Land. Discovery and naming Godel Iceport was named by United States Navy Operation Deep Freeze I personnel on the USS ''Glacier'' (AGB-4), who made a running survey of this coast in March 1956, for William H. Godel, deputy director of the Office of Special Operations, Department of the Navy, who assisted in formulating expedition plans and policy. The term "iceport" was suggested by the Advisory Committee on Antarctic Names in 1956 to denote an ice shelf indentation, subject to configuration changes, which may offer anchorage or possible access to the upper surface of an ice shelf via ice ramps along one or more sides of the feature.

Erskine Iceport
Erskine Iceport (), also known as Erskine Bay or General Erskine Bay, is an iceport about wide and long, which marks a more-or-less permanent indentation extending southeast into the seaward front of the extensive ice shelf fringing Queen Maud Land. Discovery and naming United States Navy Operation Deep Freeze I personnel on the USS ''Glacier'' made a running survey of this coast in March 1956. They applied the name "General Erskine Bay" for General Graves B. Erskine, United States Marine Corps, director of the U.S. Navy Office of Special Operations, who assisted in formulating expedition plans and policy.

Ice Pier
An ice pier or ice wharf is a man-made structure used to assist the unloading of ships in Antarctica. It is constructed by pumping seawater into a contained area and allowing the water to freeze. By repeating this procedure several times, additional layers are built up. The final structure is many metres in thickness, and strong enough to support container trucks. Operation Deep Freeze personnel constructed the first floating ice pier at Antarctica’s southernmost sea port at McMurdo Station in 1973."Unique ice pier provides harbor for ships," Antarctic Sun. January 8, 2006; McMurdo Station, Antarctica. Ice piers have been in use each season since, at McMurdo's natural [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emperor Penguin
The emperor penguin (''Aptenodytes forsteri'') is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching in length and weighing from . Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Like all penguins, it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but also includes crustaceans, such as krill, and cephalopods, such as squid. While hunting, the species can remain submerged around 20 minutes, diving to a depth of . It has several adaptations to facilitate this, including an unusually structured haemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential organ functions.
