Halley Bay
Halley Bay was a location on the fast ice on the north-western margin of the Brunt Ice Shelf in Coats Land, Antarctica. The series of British Halley Research Stations were constructed near here and named after the bay. The original ice bay was transitory and no longer exists although other bays in the same area keep reforming and breaking off as the shelf calves into icebergs. The location contains a 177 ha site which has been designated an Important Bird Area (IBA) by BirdLife International because it supported a breeding colony of about 22,500 emperor penguin The emperor penguin (''Aptenodytes forsteri'') is the tallest and heaviest of all living penguin species and is endemic to Antarctica.

Brunt Ice Shelf
The Brunt Ice Shelf borders the Antarctic coast of Coats Land between Dawson-Lambton Glacier and Stancomb-Wills Glacier Tongue. It was named by the UK Antarctic Place-names Committee after David Brunt, British meteorologist, Physical Secretary of the Royal Society, 1948–57, who was responsible for the initiation of the Royal Society Expedition to this ice shelf in 1955. It was the location of the base of the Royal Society Expedition, 1955–59 which was taken over as the British Halley Research Station. The Brunt Icefalls () extend along Caird Coast for about , where the steep ice-covered coast descends to Brunt Ice Shelf. The icefalls were discovered on 5 November 1967, in the course of a United States Navy Squadron VXE-6 flight over the coast in LC-130 aircraft, and was plotted by the United States Geological Survey from air photos obtained at that time. It was named by the Advisory Committee on Antarctic Names in association with the Brunt Ice Shelf. In 2012 previously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coats Land
Coats Land is a region in Antarctica which lies westward of Queen Maud Land and forms the eastern shore of the Weddell Sea, extending in a general northeast–southwest direction between 20°00′W and 36°00′W. The northeast part was discovered from the ''Scotia'' by William S. Bruce, leader of the Scottish National Antarctic Expedition, 1902-1904. He gave the name Coats Land for James Coats, Jr., and Major Andrew Coats, the two chief supporters of the expedition.

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] |
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 general 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 Edm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...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. The only penguin species t ... [...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 ...

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] |
