Nelson Strait (South Shetland Islands)
Nelson Strait is the 9 km long and 9.8 km wide strait lying between Robert Island and Nelson Island in the South Shetland Islands, Antarctica. The strait was explored by early 19th century sealers and first charted by Nathaniel Palmer in 1821. While it had a variety of different names in the past (‘Harmony Strait’, ‘King George’s Strait’, ‘Parry’s Straits’, Davis's Straits’, ‘Détroit de Clothier’ etc.), the present name — probably taken from the adjacent Nelson Island — has become well established in international usage. Location The strait is centred at () (early American and British mapping in 1821, British mapping in 1968, Argentine in 1946 and 1980, Chilean in 1951 and 1971, and Bulgarian mapping of the western part in 2009).

Robert Island (South Shetland Islands)
Robert Island or Mitchells Island or Polotsk Island or Roberts Island is an island long and wide, situated between Nelson Island and Greenwich Island in the South Shetland Islands, Antarctica. Robert Island is located at . Surface area . The name "Robert Island" dates back to around 1821 and is now established in international usage. Much of the Coppermine Peninsula in the west of the island is made up by a perched strandflat surface that was in past at sea level. Captain Richard Fildes may have named Robert Island for his brig . Fildes was sealing in the South Shetlands in 1821–1822 until ice destroyed his vessel in March 1822. Fildes Strait is named for him.

Nelson Island (South Shetland Islands)
Nelson Island (historical names ''Leipzig Island'', ''O'Cain's Island'' and ''Strachans Island'') is an island long and wide, lying southwest of King George Island in the South Shetland Islands, Antarctica. The name Nelson Island dates back to at least 1821 and is now established in international usage. Eco-Nelson Station The private research station Eco-Nelson is located on Nelson Island, which is one of the South Shetland Islands. The station was founded in 1988 by the Czech polar explorer Jaroslav Pavlíček. Eco-Nelson Station hosts international researchers and therefore it is not considered a Czech station.

South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...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.

Seal Hunting
Seal hunting, or sealing, is the personal or commercial hunting of seals. Seal hunting is currently practiced in ten countries: United States (above the Arctic Circle in Alaska), Canada, Namibia, Denmark (in self-governing Greenland only), Iceland, Norway, Russia, Finland and Sweden. Most of the world's seal hunting takes place in Canada and Greenland. The Canadian Department of Fisheries and Oceans (DFO) regulates the seal hunt in Canada. It sets quotas (total allowable catch – TAC), monitors the hunt, studies the seal population, works with the Canadian Sealers' Association to train sealers on new regulations, and promotes sealing through its website and spokespeople. The DFO set harvest quotas of over 90,000 seals in 2007; 275,000 in 2008; 280,000 in 2009; and 330,000 in 2010. The actual kills in recent years have been less than the quotas: 82,800 in 2007; 217,800 in 2008; 72,400 in 2009; and 67,000 in 2010. In 2007, Norway claimed that 29,000 harp seals were killed, Russ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Stonington, Connecticut, and was a descendant of Walter Palmer, one of the town's founders. Sealing career and Antarctic exploration During the 1810s the hides of Antarctic Ocean seals were highly valued as items for trade with China. Palmer served as second mate on board s first voyage, during which she became the first American vessel known to reach the South Shetland Islands. As a skilled and fearless seal hunter, Palmer achieved his first command at the early age of 21. His vessel, a diminutive sloop named , was only in length. Palmer steered southward in ''Hero'' at the beginning of the Antarctic summer of 1820–1821. Aggressively searching for new seal rookeries south of Cape Horn, on November 17, 1820, Palmer and his men became the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Straits Of The South Shetland Islands
A strait is an oceanic landform connecting two seas or two other large areas of water. The surface water generally flows at the same elevation on both sides and through the strait in either direction. Most commonly, it is a narrow ocean channel that lies between two land masses. Some straits are not navigable, for example because they are either too narrow or too shallow, or because of an unnavigable reef or archipelago. Straits are also known to be loci for sediment accumulation. Usually, sand-size deposits occur on both the two opposite strait exits, forming subaqueous fans or deltas. Terminology The terms '' channel'', ''pass'', or ''passage'' can be synonymous and used interchangeably with ''strait'', although each is sometimes differentiated with varying senses. In Scotland, ''firth'' or ''Kyle'' are also sometimes used as synonyms for strait. Many straits are economically important. Straits can be important shipping routes and wars have been fought for control of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
