arctic ocean depth in feet

The deepest point is found in the Eurasian Basin at a depth of 5,450 meters (17,880 ft.). The North Pole sits in the middle of the Arctic Ocean, on water that is almost always covered with ice. It occupies the most northern region of Earth. Pytheas of Massilia recorded an account of a journey northward in 325 BC, to a land he called "Eschate Thule", where the Sun only set for three hours each day and the water was replaced by a congealed substance "on which one can neither walk nor sail". [37] Complementing the water from the canyons, some Pacific water that does not sink to the shelf region after passing through the Bering Strait also contributes to this water mass. Even quite late in the century, the eminent authority Matthew Fontaine Maury included a description of the Open Polar Sea in his textbook The Physical Geography of the Sea (1883). [5] It is quite deep shelf sea, with average depth of 760 feet (230 m) and maximum depth of 1,480 feet (450 m) , surrounded by the shelf edge towards the Norwegian Sea in the west, the island of Svalbard (Norway) in the northwest, and the islands of Franz Josef Land and Novaya … Location. Waters originating in the Pacific and Atlantic both exit through the Fram Strait between Greenland and Svalbard Island, which is about 2,700 metres (8,900 feet) deep and 350 kilometres (220 miles) wide. [45][64] Research shows that the Arctic may become ice-free in the summer for the first time in human history by 2040. The Arctic Ocean covers an area of about 14,056,000 km2. It is mostly covered by ice all year around. Fridtjof Nansen was the first to make a nautical crossing of the Arctic Ocean, in 1896. [49] In the winter the relatively warm ocean water exerts a moderating influence, even when covered by ice. It occupies 4.3% of total ocean area. The climate of the Arctic region has varied significantly during the Earth's history. Since 1937, Soviet and Russian manned drifting ice stations have extensively monitored the Arctic Ocean. The average depth of the Arctic Ocean is 1,038 m (3,406 ft). The maximum snow cover is in March or April — about 20 to 50 cm (7.9 to 19.7 in). The situation is more drastic in many of the Arctic’s coastal areas, where August temperatures have been rising by as much as 1.8 degrees Fahrenheit (1 degree Celsius) per decade. In Norway, Kirkenes (69°43′37″N 030°02′44″E / 69.72694°N 30.04556°E / 69.72694; 30.04556 (Kirkenes)) and Vardø (70°22′14″N 031°06′27″E / 70.37056°N 31.10750°E / 70.37056; 31.10750 (Vardø)) are ports on the mainland. Important consumers of primary producers in the central Arctic Ocean and the adjacent shelf seas include zooplankton, especially copepods (Calanus finmarchicus, Calanus glacialis, and Calanus hyperboreus[59]) and euphausiids,[60] as well as ice-associated fauna (e.g., amphipods[59]). The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere, and extends south to about 60°N. The Arctic Ocean is in a polar climate. Geographical activities created deep trenches beneath the ocean that thousands of feet in depth which could part of the deepest point. The general direction of Arctic Ocean water movement below the surface is counterclockwise. Because of sea ice and remote conditions, the geology of the Arctic Ocean is still poorly explored. It covers majority of Arctic and is considered sometimes the sea of Atlantic. The average depth clocks in at just over 2 miles, or about 12,100 feet. The most northern parts of Eurasia and North America are around the Arctic Ocean. ... (1.5 feet… The Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 km2 (5,427,000 sq mi), almost the size of Antarctica. The ice is about 2-3 meters (6-10 feet) thick. In Canada, ships may anchor at Churchill (Port of Churchill) (58°46′28″N 094°11′37″W / 58.77444°N 94.19361°W / 58.77444; -94.19361 (Port of Churchill)) in Manitoba, Nanisivik (Nanisivik Naval Facility) (73°04′08″N 084°32′57″W / 73.06889°N 84.54917°W / 73.06889; -84.54917 (Nanisivik Naval Facility)) in Nunavut,[17] Tuktoyaktuk (69°26′34″N 133°01′52″W / 69.44278°N 133.03111°W / 69.44278; -133.03111 (Tuktoyaktuk)) or Inuvik (68°21′42″N 133°43′50″W / 68.36167°N 133.73056°W / 68.36167; -133.73056 (Inuvik)) in the Northwest Territories. Between this lower salinity layer and the bulk of the ocean lies the so-called halocline, in which both salinity and temperature rise with increasing depth. Year by year the Arctic Ocean is becoming less icy, as a result of global warming. Throughout the Cenozoic, the subduction of the Pacific plate, the collision of India with Eurasia and the continued opening of the North Atlantic created new hydrocarbon traps. It is the smallest ocean of all. The Arctic Ocean is the smallest of the Earth's oceans and covers about 3 percent of the world's surface area. [37] It is composed of the densest water in the World Ocean and has two main sources: Arctic shelf water and Greenland Sea Deep Water. Skip to content. Icebergs pose a hazard to ships, of which the Titanic is one of the most famous. Milwaukee Deep is the deepest part of the Atlantic Ocean. Petroleum and natural gas fields, placer deposits, polymetallic nodules, sand and gravel aggregates, fish, seals and whales can all be found in abundance in the region. Tun ATLANTIC BASIN. The agreement calls for those nations to refrain from fishing there until there is better scientific knowledge about the marine resources and until a regulatory system is in place to protect those resources. In September 2012, the Arctic ice extent reached a new record minimum. The most-recent estimate of the average ocean depth of 3,682 meters (12,080 feet) was calculated in 2010 by scientists from NOAA and Woods Hole Oceanographic Institution using satellite measurements. [39] The width of the Fram Strait is what allows for both inflow and outflow on the Atlantic side of the Arctic Ocean. [6], Human habitation in the North American polar region goes back at least 50,000–17,000 years ago, during the Wisconsin glaciation. The deepest point is Litke Deep in the Eurasian Basin, at 5,450 meters (17,880 feet). The North Pole is near the center of the Arctic Ocean. This water is met by Greenland Sea Deep Water, which forms during the passage of winter storms. The Barents Sea is a part of the Arctic Ocean, lies to the north of Norway and Russia. Countries bordering the Arctic Ocean are: Russia, Norway, Iceland, Greenland, … The average depth of the Arctic Ocean is 1,038 metres (3,406 feet). Early cartographers were unsure whether to draw the region around the North Pole as land (as in Johannes Ruysch's map of 1507, or Gerardus Mercator's map of 1595) or water (as with Martin Waldseemüller's world map of 1507). They feed on nutrients from rivers and the currents of the Atlantic and Pacific oceans. The deepest point is in the Eurasian Basin, at 5,450 m (17,881 ft). Inflow from the North Atlantic Current enters through the Fram Strait, cooling and sinking to form the deepest layer of the halocline, where it circles the Arctic Basin counter-clockwise. In fact, this water mass is actually warmer than the surface water, and remains submerged only due to the role of salinity in density. The ocean’s breadth from east to west varies considerably. March 9, 2017. [77], On 16 July 2015, five nations (United States, Russia, Canada, Norway, Denmark/Greenland) signed a declaration committing to keep their fishing vessels out of a 1.1 million square mile zone in the central Arctic Ocean near the North Pole. Deepest Point in the World's Oceans . The ocean's area is about 14.056 million km 2, which is the smallest of the world's 5 oceans, and it has 45,389 kilometres (28,203 miles) of coastline.The central surface covered by ice about 3 metres (9.8 feet) thick.The biology there is quite special. The composition of higher trophic levels in the Arctic Ocean varies with region (Atlantic side vs. Pacific side), and with the sea-ice cover. The Atlantic Ocean is essentially a basin or a large bucket stretching from north to south. An underwater ridge, the Lomonosov Ridge, divides the deep sea North Polar Basin into two oceanic basins: the Eurasian Basin, which is between 4,000 and 4,500 m (13,100 and 14,800 ft) deep, and the Amerasian Basin (sometimes called the North American, or Hyperborean Basin), which is about 4,000 m (13,000 ft) deep. Countries bordering the Arctic Ocean are: Russia, Norway, Iceland, Greenland (territory of the Kingdom of Denmark), Canada and the United States.
