Denmark Strait
The Denmark Strait () or Greenland Strait ( , 'Greenland Sound') is an oceanic strait between Greenland to its northwest and Iceland to its southeast. The Norwegian island of Jan Mayen lies northeast of the strait. Geography The strait connects the Greenland Sea, an extension of the Arctic Ocean, to the Irminger Sea, a part of the Atlantic Ocean. It stretches long and wide at its narrowest, between Straumnes, the northwestern headland of the Westfjords peninsula of Hornstrandir, and Cape Tupinier on ''Blosseville Coast'' in East Greenland. The official International Hydrographic Organization (IHO) delineation between the Arctic and the North Atlantic Oceans runs from Straumnes to Cape Nansen, southwest of Cape Tunipier. From Straumnes to Cape Nansen the distance is . Hydrography The narrow depth, where the Greenland–Iceland Rise runs along the bottom of the sea, is . The cold East Greenland Current passes through the strait and carries icebergs south into the North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Straits Of Iceland
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 them. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GIUK Gap
The GIUK gap (sometimes written G-I-UK) is an area in the northern Atlantic Ocean that forms a naval choke point. Its name is an acronym for ''Greenland, Iceland'', and the ''United Kingdom The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and North ...'', the gap being the two stretches of open ocean between these three landmasses. It separates the Norwegian Sea and the North Sea from the open Atlantic Ocean. The term is typically used in relation to military topics. The area has been considered strategically important since the beginning of the 20th century. Importance to the Royal Navy The GIUK gap is particularly important to the Royal Navy, as any attempt by northern European forces to break into the open Atlantic would have to be made either through the heavily defended English Channel ...

Aquatic Sill
An aquatic sill (or an oceanic sill) is a sea floor barrier of relatively shallow depth (tens to hundreds of meters) that restricts water movement between benthic zones of an oceanic basin or lake bottom. There are roughly 400 sills in the Earth's oceans, covering 0.01% of the seafloor. A classic example is the Strait of Gibraltar Gateway between the Mediterranean sea and the Atlantic Ocean. Formation processes Aquatic sills are common in fjords, limiting their water exchange with the ocean. After the last ice age, approximately 18,000 years ago, continental glaciers extended to the continental shelves and created U-shaped glacial valleys, with long narrow openings that rise upward near the outer shelf, thereby creating sills. Aquatic sills as barriers Circulation barriers Aquatic sills can influence water circulation by restricting the movement of bottom water masses, resulting in partial to total separation of two basins. The restricted water circulation affects tempo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Denmark Strait
The Battle of the Denmark Strait was a naval engagement in the Second World War, which took place on 24 May 1941 between ships of the Royal Navy and the ''Kriegsmarine''. The British battleship and the battlecruiser fought the German battleship and the heavy cruiser , which were attempting to break out into the North Atlantic to attack Allied merchant shipping (Operation Rheinübung). Less than 10 minutes after the British opened fire, a shell from ''Bismarck'' struck ''Hood'' near her aft ammunition magazines. Soon afterwards, ''Hood'' exploded and sank within three minutes, with the loss of all but three of her crew. ''Prince of Wales'' continued to exchange fire with ''Bismarck'' but suffered serious malfunctions in her main armament. The British battleship had only been completed in late March 1941, and used new quadruple gun turrets that were unreliable. ''Prince of Wales'' soon broke off the engagement. The battle was a tactical victory for the Germans, but its impact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denmark Strait Cataract
The Denmark Strait cataract is an undersea waterfall found on the western side of the Denmark Strait in the Atlantic Ocean, on the Arctic Circle between Iceland and Greenland. It is the world's highest underwater waterfall, with water falling almost 3,505 meters (11,500 feet). It is formed by the density difference of the water masses either side of the Denmark Strait, the eastern side being colder than the western. Due to this difference, when the two masses meet along the top ridge of the strait, the colder, denser water flows downwards and underneath the warmer, less dense water. It is thought that the Denmark Strait cataract has a flow rate exceeding 175 million cubic feet (5.0 million cubic meters) per second, making it 350 times as voluminous as the extinct Guaíra Falls on the border of Brazil and Paraguay, which was once thought to be the most voluminous waterfall on Earth, and which itself was 12 times more voluminous than Victoria Falls Victoria Falls ( Lozi: ''M ...

Fisheries
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.
