Query: Why is it called the Atlantic Ocean?
The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and the Americas to the west. As one component of the interconnected global ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Equatorial Counter Current subdivides it into the North Atlantic Ocean and the South Atlantic Ocean at about 8°N.
The Atlantic Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. As the Portuguese man o' war has no means of propulsion, they move according to the winds, currents, and tides. Although they are most commonly found in the open ocean in tropical and subtropical regions, they have been found as far north as the Bay of Fundy, Cape Breton and the Hebrides.
Atlantic () was a large supermarket chain in Greece. Atlantic supermarkets were founded in 1980 by Panayiotis Apostolou. Up to 1985 the company was a small chain with just 5 stores. After 1985 the company expanded rapidly through both organic growth and a number of acquisitions and takeovers. Atlantic was a public company and its shares used to trade in the Athens Stock Exchange from 2000 up to 2010. As of 2006–2007, the company had 182 stores nationwide and was the fifth largest supermarket chain in Greece as measured by market share. The company had also operated a franchise network of smaller stores branded "ARISTA". Since 2009 the company had suffered from serious financial difficulties (mainly due to excessive borrowing) and eventually (in 2011) went into liquidation. The company ceased all trading as of 3 August 2011.
On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values. Although the lowest salinity values are just north of the equator (because of heavy tropical rainfall), in general the lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south, in subtropical regions with low rainfall and high evaporation.
The Atlantic U-boat campaign of World War I (sometimes called the "First Battle of the Atlantic", in reference to the World War II campaign of that name) was the prolonged naval conflict between German submarines and the Allied navies in Atlantic waters—the seas around the British Isles, the North Sea and the coast of France.
The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth's southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is washed by the Southern (or Antarctic) Ocean or, depending on definition, the southern Pacific, Atlantic, and Indian Oceans. It has an area of more than 14 million km².
Astrooceanography is the study of oceans outside planet Earth. Unlike other planetary sciences like astrobiology, astrochemistry and planetary geology, it only began after the discovery of underground oceans in Saturn's Titan and Jupiter's Ganymede. This field remains speculative until further missions reach the oceans beneath the rock or ice layer of the moons. There are many theories related to celestial bodies in the Solar System, from oceans made of diamond in Neptune to a gigantic ocean of liquid hydrogen that may exist underneath Jupiter's surface.
The 1990 Atlantic hurricane season featured the most named storms of any hurricane season at the time. During the season, 14 tropical cyclones in the Atlantic Ocean became named storms. Although Tropical Depression One formed on May 24, the season officially began on June 1; it ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's final storm, Hurricane Nana, dissipated on October 21.
Atlantic Recording Corporation (simply known as Atlantic Records) is an American record label founded in October 1947 by Ahmet Ertegün and Herb Abramson. Over its first 20 years of operation, Atlantic earned a reputation as one of the most important American labels, specializing in jazz, R&B, and soul by Aretha Franklin, Ray Charles, Wilson Pickett, Sam and Dave, Ruth Brown and Otis Redding. Its position was greatly improved by its distribution deal with Stax. In 1967, Atlantic became a wholly owned subsidiary of Warner Bros.-Seven Arts, now the Warner Music Group, and expanded into rock and pop music with releases by Led Zeppelin and Yes.
The continent of Antarctica has two major divisions; West Antarctica in mostly west longitudes and East Antarctica in mostly east longitudes. East Antarctica is larger and has a higher average elevation. Separating the two subcontinents is a lower elevation topographic region occupied by the Ross Ice Shelf and the Ross Sea. This region is referred to as the Ross Embayment. The embayment comprises an area of approximately . It includes the Ross Sea () and the Ross Ice Shelf (as of 2013, ). The name is most commonly used in the scientific literature, at times along with the West Antarctic Rift System, which is of larger extent and has geologic meaning. Because the rift system includes the embayment, the later is considered to lie in West Antarcitca.
In 2004, Atlantic and its sister label Elektra were merged into Atlantic Records Group. Craig Kallman is the chairman of Atlantic. Ahmet Ertegün served as founding chairman until his death on December 14, 2006, at age 83.
The First Atlantic system was the trade of enslaved Africans to, primarily, South American colonies of the Portuguese and Spanish empires; it accounted for slightly more than 3% of all Atlantic slave trade. It started (on a significant scale) in about 1502 and lasted until 1580 when Portugal was temporarily united with Spain. While the Portuguese were directly involved in trading enslaved peoples, the Spanish empire relied on the asiento system, awarding merchants (mostly from other countries) the license to trade enslaved people to their colonies. During the first Atlantic system, most of these traders were Portuguese, giving them a near-monopoly during the era. Some Dutch, English, and French traders also participated in the slave trade. After the union, Portugal came under Spanish legislation that prohibited it from directly engaging in the slave trade as a carrier. It became a target for the traditional enemies of Spain, losing a large share of the trade to the Dutch, English, and French.
The deepest point in the ocean is the Mariana Trench, located in the Pacific Ocean near the Northern Mariana Islands. Its maximum depth has been estimated to be (plus or minus 11 meters; see the Mariana Trench article for discussion of the various estimates of the maximum depth.) The British naval vessel "Challenger II" surveyed the trench in 1951 and named the deepest part of the trench the "Challenger Deep". In 1960, the Trieste successfully reached the bottom of the trench, manned by a crew of two men.
The Prediction and Research Moored Array in the Atlantic, also known as PIRATA, is a system of moored observation buoys in the tropical Atlantic Ocean which collect meteorological and oceanographic data. The data collected by the PIRATA array helps scientists to better understand climatic events in the Tropical Atlantic and to improve weather forecasting and climate research worldwide. Climatic and oceanic events in the tropical Atlantic, such as the Tropical Atlantic SST Dipole affect rainfall and climate in both West Africa and Northeast Brazil. The northern tropical Atlantic is also a major formation area for hurricanes affecting the West Indies and the United States. Alongside the RAMA array in the Indian Ocean and the TAO/TRITON network in the Pacific Ocean, PIRATA forms part of the worldwide system of tropical ocean observing buoys.
It is charged with the responsibility of forming Iran's first line of defense in the Gulf of Oman and beyond with the mission of acting as an effective blue-water navy. However, it is generally considered as a conventional green-water navy as it mostly operates at a regional level, in the Persian Gulf and Gulf of Oman but also as far afield as the Red Sea, the Mediterranean Sea and northwest quarter of the Indian Ocean. In July 2016, the Navy said that it would establish a presence in the Atlantic Ocean, of unspecified duration.
The 2000 Atlantic hurricane season was the first Atlantic hurricane season without a tropical cyclone in the month of July since 1993. The hurricane season officially began on June 1, and ended on November 30. It was slightly above average due to a La Niña weather pattern although most of the storms were weak. The first cyclone, Tropical Depression One, developed in the southern Gulf of Mexico on June 7 and dissipated after an uneventful duration. However, it would be almost two months before the first named storm, Alberto, formed near Cape Verde; Alberto also dissipated with no effects on land. Several other tropical cyclones—Tropical Depression Two, Tropical Depression Four, Chris, Ernesto, Nadine, and an unnamed subtropical storm—did not impact land. Five additional storms—Tropical Depression Nine, Florence, Isaac, Joyce, and Leslie—minimally affected land areas.
By the 17th century, Mare Crisium had acquired the name 'Caspian Sea', being labelled as such by Thomas Harriot, Pierre Gassendi and Michael Van Langren. Ewen A. Whitaker speculates that it received this name because it occupies roughly the same position on the Moon's face as does the Caspian Sea on Earth, with respect to maps of Europe, North Africa and the Middle East. The English astronomer William Gilbert's map of "c".1600 calls it 'Brittania' after Britain.
Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. There are a number of rivers and lakes in Antarctica, the longest river being the Onyx. The largest lake, Vostok, is one of the largest sub-glacial lakes in the world. Antarctica covers more than , making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures and is mostly characterised by ice formations, as the following table shows:
Surrounded by the Indian and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas, with the Coral Sea lying off the Queensland coast, and the Tasman Sea lying between Australia and New Zealand. The world's smallest continent and sixth largest country by total area, Australia—owing to its size and isolation—is often dubbed the "island continent", and is sometimes considered the world's largest island. Australia has of coastline (excluding all offshore islands), and claims an extensive Exclusive Economic Zone of . This exclusive economic zone does not include the Australian Antarctic Territory. Apart from Macquarie Island, Australia lies between latitudes 9° and 44°S, and longitudes 112° and 154°E.
In the North Atlantic, surface circulation is dominated by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras; the North Atlantic Current, a branch of the Gulf Stream which flows northward from the Grand Banks; and the Subpolar Front, an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transport warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically.
North of the North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate variability. It is governed by ocean currents from marginal seas and regional topography, rather than being steered by wind, both in the deep ocean and at sea level.
The subpolar gyre forms an important part of the global thermohaline circulation. Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from the subtropics to the north-eastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv) current which flows around the continental margins of the Labrador Sea. A third of this water become parts of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in its turn, feed the meridional overturning circulation (MOC), the northward heat transport of which is threatened by anthropogenic climate change. Large variations in the subpolar gyre on a decade-century scale, associated with the North Atlantic oscillation, are especially pronounced in Labrador Sea Water, the upper layers of the MOC.
La Niña (, ) is a coupled ocean-atmosphere phenomenon that is the counterpart of El Niño as part of the broader El Niño–Southern Oscillation climate pattern. The name La Niña originates from Spanish, meaning "the little girl", analogous to El Niño meaning "the little boy". It has also in the past been called "anti-El Niño", and El Viejo (meaning "the old man"). During a period of La Niña, the sea surface temperature across the equatorial Eastern Central Pacific Ocean will be lower than normal by . In the United States, an "appearance" of La Niña persists for at least five months. It has extensive effects on the weather in North America, even affecting the Atlantic and Pacific hurricane seasons.
It should be noted that Balboa called the Pacific the "Mar del Sur" and referred to it as "la otra mar", the other sea, by contrast with the Atlantic, evidently with Behaim's concept of only two oceans in mind. The "Mar del Sur", the South Sea, was the part of the Indian Ocean to the south of Asia: the Indian Ocean was the "Oceanus Orientalis," the Eastern Ocean, as opposed to the Atlantic or Western Ocean, the "Oceanus Occidentalis" in Behaim's two ocean world.
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean.
The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or south of the North Pole to the subantarctic Bouvet Island at 42°S.
"Atlantic" is a drama film based on the and set aboard a fictional ship, called the "Atlantic". The main plotline revolves around a man who has a shipboard affair with a fellow passenger, which is eventually discovered by his wife. The ship also has aboard an elderly couple, the Rools, who are on their anniversary cruise. Midway across the Atlantic Ocean, the "Atlantic" strikes an iceberg and is damaged to the point where it is sinking into the Atlantic. A shortage of lifeboats causes the crew to only allow women and children in (though the captain allows a few men to take to the last remaining boats as the disaster reaches its zenith) and many couples are separated. Mrs. Rool refuses to leave her husband and after the boats are gone all the passengers gather on the deck and sing "Nearer, My God, to Thee" as the "Atlantic" sinks into the ocean. The final scenes depict a group of passengers saying the Lord's Prayer in a flooding lounge.The movie was filmed aboard the White Star Line ship RMS "Majestic". The film was originally made as "Titanic" but after lawsuits it was renamed "Atlantic". The White Star Line, which owned the RMS "Titanic", was still in operation at the time; and nevertheless had owned a major liner called which was lost in 1873. The final scene of the movie was filmed as a shot of the liner sinking, but it was cut at the last minute for fear of upsetting "Titanic" survivors.
