Hammer Point
Hammer Point is a rocky point projecting from the north coast of Robert Island in the South Shetland Islands, Antarctica into Drake Passage, and forming the southwest side of the entrance to Nevestino Cove and the northeast side of the entrance to Clothier Harbour. The point forms the north extremity of the minor Boatin Island connected to Robert Island on the south by a 250 m long moraine tombolo. The area was visited by early 19th century sealers operating from Clothier Harbour. The feature is descriptively named from its shape. Location The point is located at which is 2.08 km southwest of Catharina Point, 6.79 km west by north of Newell Point Newell Point is the rocky point forming the northeast extremity of Robert Island in the South Shetland Islands, Antarctica and is a northwest entrance point of Nelson Strait.

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.

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 bein ... [...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 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 ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drake Passage
The Drake Passage (referred to as Mar de Hoces Hoces Sea"in Spanish-speaking countries) is the body of water between South America's Cape Horn, Chile and the South Shetland Islands of Antarctica. It connects the southwestern part of the Atlantic Ocean ( Scotia Sea) with the southeastern part of the Pacific Ocean and extends into the Southern Ocean. The Drake Passage is considered one of the most treacherous voyages for ships to make. Currents at its latitude meet no resistance from any landmass, and waves top , hence its reputation as "the most powerful convergence of seas". As the Drake Passage is the narrowest passage around Antarctica, its existence and shape strongly influence the circulation of water around Antarctica and the global oceanic circulation, as well as the global climate. The bathymetry of the Drake Passage plays an important role in the global mixing of oceanic water. It is one of the most treacherous bodies of water on earth. History Sailing south from th ...

Clothier Harbour
Clothier Harbour is the 1.5 km wide bay indenting for 1 km the north coast of Robert Island in the South Shetland Islands, Antarctica between Hammer Point on the northeast and Onogur Islands on the southwest. The harbour was used as a safe base by American sealing ships in 1820–21. The bay was discovered, charted and named by American sealers after the vessel ''Clothier'' under Captain Clark, which sank there in December 1820. Location The harbour's midpoint is located at (British mapping in 1821, 1822 and 1968, Argentine in 1949, Chilean in 1962, and Bulgarian in 2009).

Boatin Island
Boatin Island ( bg, остров Боатин, ostrov Boatin, ) is the rocky island off the northwest coast of Robert Island in the South Shetland Islands extending 740 m in north–south direction and 150 m wide. It ends in the T-shaped 250 m wide Hammer Point to the north, and connected to Robert Island to the south by a 250 m long moraine tombolo. The feature was formed as a result of the retreat of Robert Island's ice cap during the first decade of 21st century. The area was visited by early 19th century sealers.

Moraine
A moraine is any accumulation of unconsolidated debris ( regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines ( till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from P ...

Tombolo
A tombolo is a sandy or shingle isthmus. A tombolo, from the Italian ', meaning 'pillow' or 'cushion', and sometimes translated incorrectly as '' ayre'' (an ayre is a shingle beach of any kind), is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a spit or bar. Once attached, the island is then known as a tied island. Several islands tied together by bars which rise above the water level are called a tombolo cluster. Two or more tombolos may form an enclosure (called a lagoon) that can eventually fill with sediment. Formation The shoreline moves toward the island (or detached breakwater) due to accretion of sand in the lee of the island, where wave energy and longshore drift are reduced and therefore deposition of sand occurs. Wave diffraction and refraction True tombolos are formed by wave refraction and diffraction. As waves near an island, they are slowed by the shallow water surrounding it. These wav ...

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, Ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
