Michelsen Island
Michelsen Island is a small island in the South Orkney Islands off Antarctica. It is joined to the southern end of Powell Island by a narrow isthmus of occasionally submerged boulders. The island was first observed and roughly mapped in 1821 by Captains George Powell and Nathaniel Palmer. It was named on a map by Captain Petter Sørlle, a Norwegian whaler who made a running survey of the South Orkney Islands in 1912–13. Important Bird Area The island lies within an Antarctic Specially Protected Area ( ASPA 111). It is also part of the Southern Powell Island and adjacent islands Important Bird Area, identified as such by BirdLife International because it supports significant seabird breeding colonies.

Southern Powell Island And Adjacent Islets Specially Protected Area
The Southern Powell Island and adjacent islets Specially Protected Area is a 2688 ha site encompassing part of southern Powell Island in the South Orkney Islands of Antarctica. It includes neighbouring Christoffersen, Fredriksen, Michelsen and Grey Islands, along with some other (unnamed) offshore islets. It was designated an Antarctic Specially Protected Area (ASPA 111, formerly SPA 15) because of its biological values as it supports many plants and animals that exemplify the natural ecology of the South Orkney Islands. It is also a breeding site for Antarctic fur seals. Important Bird Area The site has been identified as an Important Bird Area (IBA) by BirdLife International because it supports several significant seabird breeding colonies. Birds nesting there include gentoo penguins (8000 pairs), Adélie penguins (16,750 pairs), chinstrap penguins (28,100 pairs) and small numbers of macaroni penguins, as well as southern giant petrels (600 pairs), snow petrels, Cape ...

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 ...

Islands Of The South Orkney Islands
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellefsen Harbour
Ellefsen Harbour () is a harbour lying at the south end of Powell Island between Christoffersen Island and Michelsen Island, in the South Orkney Islands. It was discovered in the course of a joint cruise by Captain George Powell, a British sealer, and Captain Nathaniel Palmer Nathaniel Brown Palmer (August 8, 1799June 21, 1877) was an American seal hunter, explorer, sailing captain, and ship designer. He gave his name to Palmer Land, Antarctica, which he explored in 1820 on his sloop ''Hero''. He was born in Stoning ..., an American sealer, in December 1821. Shortly afterward, it was briefly occupied by Sam Pointer. The name first appeared on Powell's chart published in 1822.

Bird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds ( Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonie ...

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ... [...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] |
Antarctic Specially Protected Area
An Antarctic Specially Protected Area (ASPA) is an area on the continent of Antarctica, or on nearby islands, which is protected by scientists and several different international bodies. The protected areas were established in 1961 under the Antarctic Treaty System, which governs all the land and water south of 60 latitude and protects against human development. A permit is required for entry into any ASPA site. The ASPA sites are protected by the governments of Australia, New Zealand, United States, United Kingdom, Chile, France, Argentina, Poland, Russia, Norway, Japan, India, Italy, and Republic of Korea. There are currently 72 sites. List of ASPA sites See also *Antarctic Specially Managed Area An Antarctic Specially Managed Area (ASMA) is a protected area on the continent of Antarctica, or on its adjacent islands.
