Cape Roget
Cape Roget is a steep rock cape at the southern end of the east coast of the Adare Peninsula, marking the northern side of the entrance to Moubray Bay, in northern Victoria Land, Antarctica. It was discovered in 1841 by Captain James Clark Ross, who named it for Peter Mark Roget, British physician, lexicographer and Secretary of the Royal Society. Important Bird Area A 371 ha site of sea ice at the northern entrance to Moubray Bay has been designated an Important Bird Area (IBA) by BirdLife International because it supports a colony of about 9,000 breeding pairs of emperor penguin The emperor penguin (''Aptenodytes forsteri'') is the tallest and heaviest of all living penguin species and is endemic to Antarctica.

Emperor Penguins (15885611526)
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.

Adare Peninsula
The Adare Peninsula, sometimes called the Cape Adare Peninsula, is a high ice-covered peninsula, long, in the northeast part of Victoria Land, extending south from Cape Adare to Cape Roget. The peninsula is considered the southernmost point of the Borchgrevink Coast, named for Carsten Borchgrevink (1864-1934). The peninsula was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for Cape Adare. The Adare Peninsula consists of overlapping shield volcanoes that have been potassium–argon dated 6 to 13 million years old. Potassium–argon dates of 2.27 million years and perhaps 1.14 million years have also been obtained. The Adare Peninsula shields form part of the Hallett Volcanic Province of the McMurdo Volcanic Group. Named features West coast Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land. On the west side of the peninsula is Ridley Beach, a cupsate be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 .

James Clark Ross
Sir James Clark Ross (15 April 1800 – 3 April 1862) was a British Royal Navy officer and polar explorer known for his explorations of the Arctic, participating in two expeditions led by his uncle John Ross, and four led by William Edward Parry, and, in particular, for his own Antarctic expedition from 1839 to 1843. Biography Early life Ross was born in London, the son of George Ross and nephew of John Ross, under whom he entered the Royal Navy on 5 April 1812.

Peter Mark Roget
Peter Mark Roget ( ; 18 January 1779 – 12 September 1869) was a British physician, natural theologian, lexicographer and founding secretary of The Portico Library. He is best known for publishing, in 1852, the '' Thesaurus of English Words and Phrases'', a classified collection of related words. He also read a paper to the Royal Society about a peculiar optical illusion in 1824, which is often regarded as the origin of the persistence of vision theory that was later commonly used to explain apparent motion in film and animation. Early life Peter Mark Roget was born in Broad Street, Soho, London, the son of Jean (John) Roget (1751–1783), a Genevan cleric, and his wife, Catherine Romilly, sister of Samuel Romilly. After his father's death the family moved to Edinburgh in 1783 and he shortly began to study medicine at the University of Edinburgh, graduating in 1798.

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

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 ...
