Northwest Atlantic Fisheries Organization (NAFO). Following these explorations, Spain and Portugal quickly conquered and colonized large territories in the New World and forced the Amerindian population into slavery in order to explore the vast quantities of silver and gold they found. The Atlantic Ocean is divided into two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean at about 8°N. [24], Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. Near Iceland, atmospheric pressure tends to be low, and air flows in a counterclockwise direction. The Norse settlement of the Faroe Islands and Iceland began during the 9th and 10th centuries. Northeast and Northwest Atlantic Ocean Satellite Photos with NGP Pressure and Wind Overlays (NRL) Another good starting place for current Atlantic views. [6] Ocean currents influence the climate by transporting warm and cold waters to other regions. The slave trade was officially abolished in the British Empire and the United States in 1808, and slavery itself was abolished in the British Empire in 1838 and in the United States in 1865 after the Civil War. The great white shark now has an international consortium of governments, universities, and private groups studying the fearsome predator’s behavior in the northwest Atlantic Ocean. Can. Black arrows are colder, fresher water associated with the Labrador Current. Douglas B Rusch, Aaron L Halpern, Granger Sutton, Karla B Heidelberg, Shannon Williamson, Shibu Yooseph, Dongying Wu, Jonathan A Eisen, Jeff M Hoffman, Karin Remington The Atlantic Ocean is one of the world's five oceans.It is the second-largest behind the Pacific Ocean with a total area of 41,100,000 square miles (106,400,000 sq km). Northwest Atlantic Ocean and Labrador Sea bathymetry and major current systems. Thank you! Inset shows location of the Northeast Channel (NEC; sill depth ca. The winds that are cooled or warmed when blowing over these currents influence adjacent land areas. For other uses, see, Extent of the Atlantic Ocean according to the 2002 IHO definition, excluding, For complete lists of marginal seas and borders of the Atlantic, see, For the extent of the Southern Ocean, see, For a list of fracture zones in the Atlantic, see, Opening of the Central Atlantic 200-170 Ma, Sebastian A.

Sci. Overexploitation threatens the future of many large vertebrates. [58], West Gondwana (South America and Africa) broke up in the Early Cretaceous to form the South Atlantic. [86], In 1497 John Cabot became the first Western European since the Vikings to explore mainland North America and one of his major discoveries was the abundant resources of Atlantic cod off Newfoundland. [12] During the Age of Discovery, the Atlantic was also known to English cartographers as the Great Western Ocean. The Ertebølle middens in Denmark, for example, accumulated 2,000 m3 (71,000 cu ft) of shell deposits representing some 50 million molluscs over only a thousand years. [61], In the central segment rifting started to break Africa in two by opening the Benue Trough around 118 Ma. [25], The MAR rises 2–3 km (1.2–1.9 mi) above the surrounding ocean floor and its rift valley is the divergent boundary between the North American and Eurasian plates in the North Atlantic and the South American and African plates in the South Atlantic. 2010. NAFO/FC Doc. The earliest exploitation, however, took place on the now submerged shelves, and most settlements now excavated were then located several kilometers from these shelves. [53], The formation of the Central American Isthmus closed the Central American Seaway at the end of the Pliocene 2.8 Ma ago. Large quantities of basalt erupted at this time period are found on Baffin Island, Greenland, the Faroe Islands, and Scotland, with ash falls in Western Europe acting as a stratigraphic marker. The eastern water is saltier because of its proximity to Mediterranean Water. [6], The oceans are the major source of the atmospheric moisture that is obtained through evaporation. For instance, in spite of 7 km thick basalt, Gunnbjorn Field in East Greenland is the highest point on the island, elevated enough that it exposes older Mesozoic sedimentary rocks at its base, similar to old lava fields above sedimentary rocks in the uplifted Hebrides of western Scotland. Welcome. The ocean stores an enormous amount of carbon and heat, and in doing so regulates Earth’s climate. Total catches have been fluctuating since the 1970s; reaching 3.9 million tons in 2013 or slightly less than the peak production in 2010. The sea snail perlemoen abalone is targeted by illegal fishing and remain overfished. Ocean. [6], The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. Loggerhead sea turtle critical habitat map and associated data files for the Northwest Atlantic Ocean DPS. The Gulf Stream and North Atlantic Current System are the key elements of northward heat transport and Meridional Overturning Circulation in the Atlantic Ocean. For their own safety, the crew jettisoned two nuclear bombs, which were never recovered. A. R. 1. [24], The MAR divides the Atlantic longitudinally into two-halves, in each of which a series of basins are delimited by secondary, transverse ridges. Atlantic Ocean, body of salt water covering about one-fifth of Earth’s surface and separating the continents of Europe and Africa to the east from those of North and South America to the west. White arrows are warmer, saltier water associated with the Gulf Stream. Explore {{searchView.params.phrase}} by color family {{familyColorButtonText(colorFamily.name)}} portland head light - northwest atlantic ocean stock pictures, royalty-free photos & images . [42], The Sargasso Sea in the western North Atlantic can be defined as the area where two species of Sargassum (S. fluitans and natans) float, an area 4,000 km (2,500 mi) wide and encircled by the Gulf Stream, North Atlantic Drift, and North Equatorial Current. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 (31,570,000 sq mi) and has a volume of 305,811,900 km3 (73,368,200 cu mi). The North Atlantic garbage patch is estimated to be hundreds of kilometers across in size.[90]. In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The residence time of the gyre is 4.4–8.5 years. In the early 1990s, this finally resulted in the collapse of the Atlantic northwest cod fishery. [65] Human history thus begins on the coasts of South Africa where the Atlantic Benguela Upwelling and Indian Ocean Agulhas Current meet to produce an intertidal zone on which shellfish, fur seal, fish and sea birds provided the necessary protein sources. Rep. Hydrogr. [1][18], Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 (41,100,000 sq mi) or 23.5% of the global ocean and has a volume of 310,410,900 km3 (74,471,500 cu mi) or 23.3% of the total volume of the earth's oceans. The North Atlantic provides a critical link in global ocean circulation, with local surface waters sinking and forming the deep ocean conveyor. NCEI Regional Climatology Team1 developed a new set of high-resolution quality-controlled long-term ", "The geological history of the North Atlantic Ocean", Atlantic Continental Shelf and Slope of the United States, "Problems and Prospects for the Pelagic Driftnet", "Huge Garbage Patch Found in Atlantic Too", Armed Forces Radiobiology Research Institute, "The rise of Europe: Atlantic trade, institutional change and economic growth", "All roads lead to home: panmixia of European eel in the Sargasso Sea", "The Ysterfontein 1 Middle Stone Age rock shelter and the evolution of coastal foraging", "Archaeology of the continental shelf: marine resources, submerged landscapes and underwater archaeology", "Zircon U-Pb geochronology links the end-Triassic extinction with the Central Atlantic Magmatic Province", "Decadal variability of subpolar gyre transport and its reverberation in the North Atlantic overturning", "Exploring the analogy between modern trafficking in humans and the trans-Atlantic slave trade", "Slowing of the Atlantic meridional overturning circulation at 25 N", "The fit of the continents around the Atlantic", "Are subduction zones invading the Atlantic? Open Data. It also expanded the exploited areas from near-shore to the open sea and to great depths to include deep-water species such as redfish, Greenland halibut, witch flounder, and grenadiers. 21st-century global warming will probably result in an equilibrium sea-level rise five times greater than today, whilst melting of glaciers, including that of the Greenland ice-sheet, expected to have virtually no effect during the 21st century, will probably result in a sea-level rise of 3–6 m over a millennium. Stocks of invertebrates, in contrast, remain at record levels of abundance. The MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other. In the southwestern North Atlantic Ocean, the area between the 80F isotherm and the equator, and between 30W longitude and the western most land boundary, is compiled for each month from a world atlas of sea surface temperatures. Tech. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft).[25]. [6], The shelves of the Atlantic hosts one of the world's richest fishing resources. For purposes of this section, the term "underutilized species of the northwest Atlantic Ocean" means any fish species of the northwest Atlantic Ocean that is identified, by the Director of the Northeast Fisheries Center of the National Marine Fisheries Service, as an underutilized species. Select from premium Northwest Atlantic Ocean of the highest quality. [86], Endangered marine species include the manatee, seals, sea lions, turtles, and whales. Evidence from the southwest Iberia margin", "Norse Greenland settlement: reflections on climate change, trade, and the contrasting fates of human settlements in the North Atlantic islands", "Volumes of the World's Oceans from ETOPO1", The State of World Fisheries and Aquaculture, "Cyclonic gyre in the tropical South Atlantic", "Emergence of modern human behavior: Middle Stone Age engravings from South Africa", "The beginnings of the Sargasso assemblage in the Tethys? [10] On the other hand, to early Greek sailors and in Ancient Greek mythological literature such as the Iliad and the Odyssey, this all-encompassing ocean was instead known as Oceanus, the gigantic river that encircled the world; in contrast to the enclosed seas well known to the Greeks: the Mediterranean and the Black Sea. [89], Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. The NADW is fed by a flow of warm shallow water into the northern North Atlantic which is responsible for the anomalous warm climate in Europe. DOI: 10.4236/ns.2020.126028 PDF HTML XML 32 Downloads 186 Views Abstract . This population of seaweed probably originated from Tertiary ancestors on the European shores of the former Tethys Ocean and has, if so, maintained itself by vegetative growth, floating in the ocean for millions of years. [24], Continental shelves in the Atlantic are wide off Newfoundland, southernmost South America, and north-eastern Europe. Between the 15th century and 1888, when Brazil became the last part of the Americas to end the slave trade, an estimated ten million Africans were exported as slaves, most of them destined for agricultural labour. Polar DMSP/AMSU Imagery. Since man-made substances were introduced into the environment, the path of the NADW can be traced throughout its course by measuring tritium and radiocarbon from nuclear weapon tests in the 1960s and CFCs. Fig. The northwest Atlantic coast in Canada has been divided into boreal and subarctic biogeographic regions based on temperature and environmental conditions (Briggs, 1974), but as proposed by Adey and Steneck (2001), the subarctic region extends south down into the Gulf of St. Lawrence, encompassing Labrador, the northern half of Newfoundland, and the northern gulf shore of … Access Data - Submit Data - Intended Use of the Data? [66] North Atlantic Central Water can be divided into the Eastern and Western North Atlantic central Water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. Map Name: Monthly_Currents_NorthwestAtlanticOcean_19902015_FR Legend All Layers and Tables Dynamic … 211):[7] Atlantikôi pelágei (Greek: Ἀτλαντικῷ πελάγει; English: 'the Atlantic sea'; etym. In contrast, 8–7 kya-old shell middens in Portugal, Denmark, and Brazil generated thousands of tons of debris and artefacts. The Canadian Atlantic Ocean is divided into three bioregions: the Newfoundland and Labrador Shelves (NL), the Scotian Shelf (SS), and the Gulf of St. Lawrence (GSL) ().Each bioregion is based on geographic differences in ocean conditions and depth and has distinct characteristics. Southeast. In the North-East Atlantic 21% of stocks are considered overfished. Northwest Atlantic Ocean and Labrador Sea bathymetry and major current systems. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and the Americas to the west. Northwest Atlantic Ocean and Labrador Sea bathymetry and major current systems. 1.202.4): Atlantis thalassa (Greek: Ἀτλαντὶς θάλασσα; English: 'Sea of Atlantis' or 'the Atlantis sea'[8]) where the name refers to "the sea beyond the pillars of Heracles" which is said to be part of the sea that surrounds all land. 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. Dyke swarms in Brazil, Angola, eastern Paraguay, and Namibia, however, suggest the LIP originally covered a much larger area and also indicate failed rifts in all these areas. In the Atlantic Ocean the water flow is predominantly from west to east driven by the northern and southern branches of the North Atlantic Drift. [28] A much vaguer, nameless boundary, between the North American and South American plates, intersects the MAR near or just north of the Fifteen-Twenty Fracture Zone, approximately at 16°N.[29]. The term dates to as early as 1640, first appearing in print in pamphlet released during the reign of Charles I, and reproduced in 1869 in Nehemiah Wallington's Historical Notices of Events Occurring Chiefly in The Reign of Charles I, where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank, Charles I's Secretary of State.[14][15][16]. Overfishing in the area was recognised as early as the 1960s but, because this was occurring on international waters, it took until the late 1970s before any attempts to regulate was made. Welcome to Atlantic Whales, an on-line catalogue of whale sightings in the northwest Atlantic Ocean. Off South Africa and Namibia deep-water hake and shallow-water Cape hake have recovered to sustainable levels since regulations were introduced in 2006 and the states of Southern African pilchard and anchovy have improved to fully fished in 2013. Metrics details. Meanwhile, the Scotia Arc and Caribbean Plate in the western Atlantic Basin are eastward-propagating subduction systems that might, together with the Gibraltar system, represent the beginning of the closure of the Atlantic Ocean and the final stage of the Atlantic Wilson cycle. While nine of these have collectively been nominated a World Heritage Site for their geological value, four of them are considered of "Outstanding Universal Value" based on their cultural and natural criteria: Þingvellir, Iceland; Landscape of the Pico Island Vineyard Culture, Portugal; Gough and Inaccessible Islands, United Kingdom; and Brazilian Atlantic Islands: Fernando de Noronha and Atol das Rocas Reserves, Brazil. H2.21.0 is a map of the Northwest Atlantic (Major Fishing Area 21) corresponding to the NAFO Convention Area. Stocks of northern shrimp and Norwegian lobster are in good condition. NIOZ hosts an observational ocean network to study deep water formation. [79], Christopher Columbus reached the Americas in 1492 under Spanish flag. The status of most shark species, in contrast, remains uncertain. The Landnámabók (Book of Settlement) records disastrous famines during the first century of settlement — "men ate foxes and ravens" and "the old and helpless were killed and thrown over cliffs" — and by the early 1200s hay had to be abandoned for short-season crops such as barley. Research shows links between collapse of fisheries and bottom-living species . For the ocean dynamics, similar to the observed sea level, we assume that the temporal autocorrelation of the noise follows a Generalized Gauss‐Markov distribution. [39] [64], Humans evolved in Africa; first by diverging from other apes around 7 mya; then developing stone tools around 2.6 mya; to finally evolve as modern humans around 100 kya. Many translated example sentences containing "Northwest Atlantic Ocean" – French-English dictionary and search engine for French translations. In the 1870s, the Challenger expedition discovered parts of what is now known as the Mid-Atlantic Ridge, or: An elevated ridge rising to an average height of about 1,900 fathoms [3,500 m; 11,400 ft] below the surface traverses the basins of the North and South Atlantic in a meridianal direction from Cape Farewell, probably its far south at least as Gough Island, following roughly the outlines of the coasts of the Old and the New Worlds. Around 150 Ma sea-floor spreading propagated northward into the southern segment. Northwest Atlantic Fisheries Organization (NAFO). The African origin of this modern behaviour is evidenced by 70,000 years-old engravings from Blombos Cave, South Africa. Regional Climatology > Due to a consistently strong wind shear and a weak Intertropical Convergence Zone, South Atlantic tropical cyclones are rare. The most productive areas include the Grand Banks of Newfoundland, the Scotian Shelf, Georges Bank off Cape Cod, the Bahama Banks, the waters around Iceland, the Irish Sea, the Bay of Fundy, the Dogger Bank of the North Sea, and the Falkland Banks. Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from the subtropics to the north-eastern Atlantic. They could explore the convoys leaving the Americas because prevailing winds and currents made the transport of heavy metals slow and predictable. The Northwest Atlantic Marine Ecoregional Assessment (NAM ERA) synthesized comprehensive data on species distributions, geology, oceanography, chemistry, biology and social science. [86], In the North-West Atlantic landings have decreased from 4.2 million tons in the early 1970s to 1.9 million tons in 2013. Northwest Atlantic Ocean circulation bias (i.e. Other pollution concerns include agricultural and municipal waste. The oldest oceanic crust in the Atlantic is up to 145 million years and situated off the west coast of Africa and east coast of North America, or on either side of the South Atlantic. Colonialism evolved as part of the Trans-Atlantic trade, but this trade also strengthened the position of merchant groups at the expense of monarchs. 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. [61], Geologically the South Atlantic can be divided into four segments: Equatorial segment, from 10°N to the Romanche Fracture Zone (RFZ);; Central segment, from RFZ to Florianopolis Fracture Zone (FFZ, north of Walvis Ridge and Rio Grande Rise); Southern segment, from FFZ to the Agulhas-Falkland Fracture Zone (AFFZ); and Falkland segment, south of AFFZ. Arctic Intermediate Water, flows from north to become the source for North Atlantic Deep Water south of the Greenland-Scotland sill. Northwest Atlantic Fisheries Organization conservation and enforcement measures. H2.21.0 is a map of the Northwest Atlantic (Major Fishing Area 21) corresponding to the NAFO Convention Area. Following rapid climate changes at the end of the LGM this region was repopulated by Magdalenian culture. [83], Trans-Atlantic trade also resulted in increasing urbanization: in European countries facing the Atlantic, urbanization grew from 8% in 1300, 10.1% in 1500, to 24.5% in 1850; in other European countries from 10% in 1300, 11.4% in 1500, to 17% in 1850. In the ocean, tunas and sea turtles are current conservation concerns because of this intense pressure. The extent of the volcanism has been estimated to 4.5×106 km2 (1.7×106 sq mi) of which 2.5×106 km2 (9.7×105 sq mi) covered what is now northern and central Brazil. 44% of stocks are being fished at unsustainable levels. Likewise, GDP doubled in Atlantic countries but rose by only 30% in the rest of Europe. [69] The European coasts of the North Atlantic were permanently populated about 9–8.5 thousand years ago. Home > Its name, derived from Greek mythology, means the ‘Sea of Atlas.’ It is second in size to the Pacific Ocean. The most important species in the area, Gulf menhaden, reached a million tons in the mid-1980s but only half a million tons in 2013 and is now considered fully fished. Northwest Atlantic Ocean’s SSTs Kern E. Kenyon. [70], This human dispersal left abundant traces along the coasts of the Atlantic Ocean. Traces of magmatism in both offshore and onshore basins in the central and southern segments have been dated to 147–49 Ma with two peaks between 143 and 121 Ma and 90–60 Ma. In the middle latitudes, the area of maximum temperature variations, values may vary by 7–8 °C (13–14 °F). The subpolar gyre forms an important part of the global thermohaline circulation. In 1500, in his voyage to India following Vasco da Gama, Pedro Alvares Cabral reached Brazil, taken by the currents of the South Atlantic Gyre. Geologists distinguish two magmatic phases. Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and Northern Africa. The term "Aethiopian Ocean", derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century. [51], The opening of the Atlantic Ocean coincided with the initial break-up of the supercontinent Pangaea, both of which were initiated by the eruption of the Central Atlantic Magmatic Province (CAMP), one of the most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event, one of Earth's major extinction events. The Intergovernmental Panel on Climate Change (IPCC) fifth assessment of projected global and regional ocean temperature change is based on global climate models that have coarse (~100-km) ocean and atmosphere resolutions. [92] Therefore, these changes in SST must be caused by human activities. [59] Intra-continental rifts and deformations have also been introduced to subdivide both continental plates into sub-plates. Subscribe to the CLIVAR monthly bulletin … Please contact NCEI.Info@noaa.gov with any questions of issues. Northwest Atlantic GOES-8 IR Satellite Photo with AVN Pressure and Wind Overlay (SOEST) Great starting place for current Northwest Atlantic overview. There is a temperature difference of more than 20°C between arctic waters and the Gulf Stream, which brings water from the equatorial Atlantic to the Maritimes before traveling east across the ocean towards Europe. North Atlantic Deep Water flows southward below the thermocline of the subtropical gyre. annual, seasonal and monthly mean temperature and salinity fields on different depth levels. Rifting in the central segment, however, coincided with the Cretaceous Normal Superchron (also known as the Cretaceous quiet period), a 40 Ma period without magnetic reversals, which makes it difficult to date sea-floor spreading in this segment. The list includes ships that sank, foundered, grounded, or were otherwise lost. Flora.The vegetable life of the Atlantic Ocean is very diverse. Both these currents receive some contribution from the Indian Ocean. Climatic zones vary with latitude; the warmest zones stretch across the Atlantic north of the equator. Flora.The vegetable life of the Atlantic Ocean is very diverse. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels.[25]. [88], Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The Laurentian Abyss is found off the eastern coast of Canada. This assessment spans the area from Cape Hatteras in North Carolina to the northern limit of the Gulf of Maine in Canadian waters. A 2005 report indicated that the Atlantic meridional overturning circulation (AMOC) slowed down by 30% between 1957 and 2004. Weather over the North Atlantic is largely determined by large-scale wind currents and air masses emanating from North America. [6], 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. To provide an improved oceanographic foundation and reference for multi-disciplinary studies of the NWA, Inspired designs on t-shirts, posters, stickers, home decor, and more by independent artists and designers from around the world. Marine species responded to warmer temperatures by shifting their geographic distribution and seasonal cycles. Changes in the formation of NADW have been linked to global climate changes in the past. Black arrows are colder, fresher water associated with the Labrador Current. The Northwest Atlantic Ocean and Shelf is a region where colder, fresher Shelf and Slope Waters from the North (Labrador Current) converges with warmer, … The Atlantic Ocean is the second-largest of the world's oceans, with an area of about 106,460,000 km2 (41,100,000 sq mi). Such a passage, often called the Northwest Passage, would connect Europe to Asia via shorter routes than the long voyage south around Africa. At the same time, a less visible heat wave was occurring over a large portion of the Northwest Atlantic Ocean. This did not last, however, and temperatures quickly dropped; at 1080 CE summer temperatures had reached a maximum of 5 °C (41 °F). In spite of the important role of kelp in the nearshore temperate ecosystems of the northwest Atlantic Ocean and their vulnerability to perturbation by climate change, we can find no evidence based on the reviewed literature for latitudinal shifts in the geographic distribution of key kelp species. BNAM: An eddy resolving North Atlantic Ocean model to support ocean monitoring. Round sardinella was an important species in the 1990s but is now considered overfished.

High quality Northwest Atlantic Ocean gifts and merchandise. Arctic saithe and haddock are considered fully fished; Sand eel is overfished as was capelin which has now recovered to fully fished. 43 Citations. "[73] Others later proposed a "three-wave" migration over the Bering Land Bridge. The Atlantic Ocean is bounded on the west by North and South America. [92] 'Sea of Atlantis') and in The Histories of Herodotus around 450 BC (Hdt. The Atlantic Ocean is underlain mostly by dense mafic oceanic crust made up of basalt and gabbro and overlain by fine clay, silt and siliceous ooze on the abyssal plain. PDF Shapefile Map | New England/Mid-Atlantic. This new regional climatology is based on the World Ocean Database archive of temperature and salinity from observations spanning over more This area of the North Atlantic is known as the NorthWest Approaches (NWA). This report covers the North-east Atlantic Ocean, which includes the European part of the Atlantic, also defined as area 3, 4 and 5 by the OSPAR convention. First small ocean basins opened and a shallow gateway appeared during the Middle Eocene. [35], The North Atlantic Deep Water (NADW) is a complex of four water masses, two that form by deep convection in the open ocean — Classical and Upper Labrador Sea Water — and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill — Denmark Strait and Iceland-Scotland Overflow Water. The Gulf Stream and North Atlantic Current System are the key elements of northward heat transport and Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values. Loggerhead Turtle – Northwest Atlantic Ocean DPS Critical Habitat Map.
