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. The Inuvik-to-Tuk Highway is a major milestone for Canada – connecting our country for the first time by road from Coast to Coast to Arctic Coast. [37] As it is entrained, it cools and acts a heat shield for the surface layer. Mean surface circulation is predominately cyclonic on the Eurasian side and anticyclonic in the Canadian Basin. Icebergs pose a hazard to ships, of which the Titanic is one of the most famous. However, meals can be a few days apart or even a few months. The rifting apart of the supercontinent Pangea, beginning in the Triassic opened the early Atlantic Ocean. The Arctic Ocean covers much of the Arctic and washes upon Northern America and Eurasia.It is sometimes considered a sea or estuary of the Atlantic Ocean.. 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. Arctic Ocean ) - - - - | Quakes (show) all >M3 >M4 >M5 >M6 M7+ / past 24h - past 48h - past week - past 2 weeks / Archive. He was probably describing loose sea ice known today as "growlers" or "bergy bits"; his "Thule" was probably Norway, though the Faroe Islands or Shetland have also been suggested.[10]. In the United States in the 1850s and 1860s, the explorers Elisha Kane and Isaac Israel Hayes both claimed to have seen part of this elusive body of water. ], Yenikeyeff, Shamil and Krysiek, Timothy Fenton (August 2007), Allied commitment to resupply the Soviet Union via its northern ports, Some Thoughts on the Freezing and Melting of Sea Ice and Their Effects on the Ocean, "Arctic Sea Ice News and Analysis | Sea ice data updated daily with one-day lag", "Understanding the Arctic sea ice: Polar Portal", "The Late Pleistocene Dispersal of Modern Humans in the Americas", "Channel 4, "Sir Wally Herbert dies" 13 June 2007", North Pole drifting stations (1930s–1980s), "Backgrounder – Expanding Canadian Forces Operations in the Arctic", "Five Deeps Expedition is complete after historic dive to the bottom of the Arctic Ocean", "Sea Around Us | Fisheries, Ecosystems and Biodiversity", "World Map / World Atlas / Atlas of the World Including Geography Facts and Flags - WorldAtlas.com". The new map is promoted by the International Bathymetric Chart of the Arctic Ocean (IBCAO) and expands up to a 19.6% the submarine surface mapped in previous versions. Map without sea ice. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere, and extends south to about 60°N. Cyclones are more frequent in summer and may bring rain or snow. [60] In ice-covered regions of the central Arctic Ocean, polar cod is a central predator of primary consumers. Select from the other forecast maps (on the right) to view the temperature, cloud cover, wind and precipitation for this country on a large scale with animation. Reduced sea ice due to melting is causing polar bears to search for new sources of food. Water in the Beaufort Gyre is far less saline than that of the Chukchi Sea due to inflow from large Canadian and Siberian rivers.[40]. The map below shows the regional seas that make up the Arctic Ocean, along with other geographical features. [16][45], The political dead zone near the center of the sea is also the focus of a mounting dispute between the United States, Russia, Canada, Norway, and Denmark. The final defined water mass in the Arctic Ocean is called Arctic Surface Water and is found from 150–200 metres (490–660 feet). Whether your map is paper or digital, mastering the basics of reading it are vital to finding your way around and understanding how the world works. Purple signifies sea-ice thickness of approximately ½ to 1½ meters (20 inches to 5 ft). 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). It is connected to the Pacific Ocean by the Bering Strait and to the Atlantic Ocean through the Greenland Sea and Labrador Sea. The map is the 4.0 version of the International Bathymetric Chart of the Arctic Ocean (IBCAO), an initiative that was created in 1997 in Saint Petersburg (Russia) in order to map the depths of the Arctic floors. The low shifts to center over the North Pole in the summer. Due to the pronounced seasonality of 2–6 months of midnight sun and polar night[57] in the Arctic Ocean, the primary production of photosynthesizing organisms such as ice algae and phytoplankton is limited to the spring and summer months (March/April to September[58]). It is sometimes classified as an estuary of the Atlantic Ocean,[2][3] and it is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. [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. Additional spreading helped to create the "triple-junction" of the Alpha-Mendeleev Ridge in the Late Cretaceous. NSIDC scientists often refer to the different seas within the Arctic Ocean … Source: EEA The area includes many fjords with rivers flowing into them. The composition of higher trophic levels in the Arctic Ocean varies with region (Atlantic side vs. Pacific side), and with the sea-ice cover. [67], Warming temperatures in the Arctic may cause large amounts of fresh meltwater to enter the north Atlantic, possibly disrupting global ocean current patterns. 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. 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. Endangered marine species in the Arctic Ocean include walruses and whales. The makers of navigational charts, more conservative than some of the more fanciful cartographers, tended to leave the region blank, with only fragments of known coastline sketched in. Water in the shelf region that begins as inflow from the Pacific passes through the narrow Bering Strait at an average rate of 0.8 Sverdrups and reaches the Chukchi Sea. A bear, usually to preserve energy, can sleep in any position. The speed of the ice drift is roughly 1–4 cm/s. Since 1937, Soviet and Russian manned drifting ice stations have extensively monitored the Arctic Ocean. About Arctic Ocean: The Facts: Area: 5,427,000 sq … For example, the Beaufort High—an extension of the Siberian High system—is a pressure system that drives the anticyclonic motion of the Beaufort Gyre. In Alaska, the main ports are Barrow (71°17′44″N 156°45′59″W / 71.29556°N 156.76639°W / 71.29556; -156.76639 (Barrow)) and Prudhoe Bay (70°19′32″N 148°42′41″W / 70.32556°N 148.71139°W / 70.32556; -148.71139 (Prudhoe)). Much of the Arctic ice pack is also covered in snow for about 10 months of the year. [38] This process leaves dense, salty waters in the sea that sink over the continental shelf into the western Arctic Ocean and create a halocline.[40]. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. 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 Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features; the Bering Strait on the Pacific side, and the Greenland Scotland Ridge on the Atlantic side. [8], The Thule Tradition lasted from about 200 BC to AD 1600 around the Bering Strait, the Thule people being the prehistoric ancestors of the Inuit who now live in Northern Labrador.
