Weddell Sea
The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea. Much of the southern part of the sea is covered by a permanent, massive ice shelf field, the Filchner-Ronne Ice Shelf. The sea is contained within the two overlapping Antarctic territorial claims of Argentine Antarctica, the British Antarctic Territory, and also resides partially within the Antarctic Chilean Territory. At its widest the sea is around across, and its area is around . Various ice shelves, including the Filchner-Ronne Ice Shelf, fringe the Weddell sea. Some of the ice shelves on the east side of the Antarctic Peninsula, which formerly covered roughly of the Weddell Sea, had completely disappeared by 2002. The Weddell Sea has been deemed b ...

Wandel Sea
The Wandel Sea ( da, Wandelhavet; also known as McKinley Sea) is a body of water in the Arctic Ocean, stretching from northeast of Greenland to Svalbard. It is obstructed by ice most of the year. This sea is named after Danish polar explorer and hydrographer, Vice Admiral Carl Frederick Wandel, who in the years 1895–96 explored the coastal waters of Greenland as part of the Danish Ingolf Expedition. Geography This arctic sea is located at 82° north longitude and 21° west latitude. Seas farther north and northwest of the Wandel Sea were once frozen year-round but now may have open water in late summer, as of August 2018.ftp://ftp-projects.cen.uni-hamburg.de/seaice/AMSR2/3.125km/ The Wandel Sea stretches westward as far as Cape Morris Jesup. Further west is the Lincoln Sea. In the south, it stretches to Nordostrundingen. The Wandel Sea connects to the Greenland Sea in the south through the Fram Strait. Independence Fjord and Frederick E.

Secchi Disc
The Secchi disk (or Secchi disc), as created in 1865 by Angelo Secchi, is a plain white, circular disk in diameter used to measure water transparency or turbidity in bodies of water. The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity. Since its invention, the disk has also been used in a modified, smaller diameter, black and white design to measure freshwater transparency. Similar disks, with a black-and-yellow pattern, are used as fiducial markers on vehicles in crash tests, crash-test dummies, and other kinetic experiments. History The original Secchi disk was a plain white disk and was used in the Mediterranean Sea. Today, a plain white, diameter Secchi disk remains the standard design used in marine studies. In 1899 George C. Whipple modified the original all-white S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thermohaline
Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective ''thermohaline'' derives from '' thermo-'' referring to temperature and ' referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk of it upwells in the Southern Ocean, the oldest waters (with a transit time of about 1000 years) upwell in the North Pacific. Extensive mixing therefore takes place between the ocean basins, reducing differences between them and making the Earth's oceans a global system. The water in these circuits transport both energy (in the form of heat) and mass (dissolved solids and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabbeling
Cabbeling is when two separate water parcels mix to form a third which sinks below both parents. The combined water parcel is denser than the original two water parcels. The two parent water parcels may have the same density, but they have different properties; for instance, different salinities and temperatures.Beer, Tom (1997). Environmental oceanography. Boca Raton: CRC Press. p. 123. , Section 5.4.3 Cabbeling. Seawater almost always gets denser if it gets ''either'' slightly colder ''or'' slightly saltier. But medium-warm, medium-salty water can be denser than both fresher, colder water and saltier, warmer water; in other words, the equation of state for seawater is monotonic, but non-linear. See diagram. Cabbeling may also occur in fresh water, since pure water is densest at about 4 °C (39 °F). A mixture of 1 °C water and 6 °C water, for instance, might have a temperature of 4 °C, making it denser than either parent. Ice is also less dense than water, s ...

William Speirs Bruce
William Speirs Bruce (1 August 1867 – 28 October 1921) was a British naturalist, polar scientist and oceanographer who organized and led the Scottish National Antarctic Expedition (SNAE, 1902–04) to the South Orkney Islands and the Weddell Sea. Among other achievements, the expedition established the first permanent weather station in Antarctica. Bruce later founded the Scottish Oceanographical Laboratory in Edinburgh, but his plans for a transcontinental Antarctic march via the South Pole were abandoned because of lack of public and financial support. In 1892 Bruce gave up his medical studies at the University of Edinburgh and joined the Dundee Whaling Expedition to Antarctica as a scientific assistant. This was followed by Arctic voyages to Novaya Zemlya, Spitsbergen and Franz Josef Land. In 1899 Bruce, by then Britain's most experienced polar scientist, applied for a post on Robert Falcon Scott's Discovery Expedition, but delays over this appointment and clashes w ...

New South Greenland
New South Greenland, sometimes known as Morrell's Land, was an appearance of land recorded by the American captain Benjamin Morrell of the schooner ''Wasp'' in , during a sealing and exploration voyage in the Weddell Sea area of Antarctica. Morrell provided precise coordinates and a description of a coastline which he claimed to have sailed along for more than . Because the Weddell Sea area was so little visited and hard to navigate due to ice conditions, the alleged land was never properly investigated before its existence was emphatically disproved during Antarctic expeditions in the early 20th century. At the time of Morrell's voyage, the geography of the then unnamed Weddell Sea and its surrounding coasts was almost entirely unknown, making the claimed sighting initially plausible. However, obvious errors in Morrell's voyage account and his general reputation as a fabulist created scepticism about the existence of this new land. In the German explorer Wilhelm Filchner sea ...

George IV Of The United Kingdom
George IV (George Augustus Frederick; 12 August 1762 – 26 June 1830) was King of the United Kingdom of Great Britain and Ireland and King of Hanover from the death of his father, King George III, on 29 January 1820, until his own death ten years later. At the time of his accession to the throne, he was acting as Prince Regent, having done so since 5 February 1811, during his father's final mental illness. George IV was the eldest child of King George III and Queen Charlotte. He led an extravagant lifestyle that contributed to the fashions of the Regency era. He was a patron of new forms of leisure, style and taste. He commissioned John Nash to build the Royal Pavilion in Brighton and remodel Buckingham Palace, and commissioned Jeffry Wyatville to rebuild Windsor Castle. George's charm and culture earned him the title "the first gentleman of England", but his dissolute way of life and poor relationships with his parents and his wife, Caroline of Brunswick, earned h ...

James Weddell
James Weddell (24 August 1787 – 9 September 1834) was a British sailor, navigator and seal hunter who in February 1823 sailed to latitude of 74° 15′ S—a record 7.69 degrees or 532 statute miles south of the Antarctic Circle—and into a region of the Southern Ocean that later became known as the Weddell Sea. Early life He was born in Ostend on the Belgian coast, the son of a Scottish sea captain (captains were permitted their wives at sea). He was apprenticed as a seaman (this normally started at age eight) and so received little education, but clearly could at least read and write. He originally worked on merchant ships on the north-east Scottish coast. He entered the merchant service very early in his life and was apparently bound to the master of a Newcastle collier (a coal transport vessel) for some years. About 1805 he shipped on board a merchantman trading to the West Indies, making several voyages there. In 1808 he struck his captain, w ...

Ice Floe
An ice floe () is a large pack of floating ice often defined as a flat piece at least 20 m across at its widest point, and up to more than 10 km across. Drift ice is a floating field of sea ice composed of several ice floes. They may cause ice jams on freshwater rivers, and in the open ocean may damage the hulls of ships. Gallery File:Drift ice in Hudson Strait, 2014.jpg, Several ice floes in the Hudson Strait Hudson Strait (french: Détroit d'Hudson) links the Atlantic Ocean and Labrador Sea to Hudson Bay in Canada.
