Secondary consumers in the Barents Sea, an Atlantic-influenced Arctic shelf sea, are mainly sub-Arctic species including herring, young cod, and capelin. Similar Illustrations See All. [47] Summers are characterized by continuous daylight (midnight sun), and air temperatures can rise slightly above 0 °C (32 °F). amzn_assoc_ad_type = "smart"; This water is met by Greenland Sea Deep Water, which forms during the passage of winter storms. 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. Icebergs pose a hazard to ships, of which the Titanic is one of the most famous. Map 1: Arctic Ocean physiography (depth distribution and main currents in the European part) Note: The sea area between Greenland and Norway is often called the Nordic Seas. It is an extension of the Icelandic Low, which creates cyclonic ocean circulation in this area. [1] The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years, showing a continuous decline in sea ice extent. Winters are characterized by the polar night, extreme cold, frequent low-level temperature inversions, and stable weather conditions. Coordinates: 90°N 0°E / 90°N 0°E / 90; 0. Look at this map. These primary consumers form an important link between the primary producers and higher trophic levels. The coastline is estimated to be 45,390 km (28,200 mi) long. The Siberian Shelf holds large oil and gas reserves, and the Chukchi shelf forms the border between Russian and the United States as stated in the USSR–USA Maritime Boundary Agreement. [47] It is cloudy year-round, with mean cloud cover ranging from 60% in winter to over 80% in summer.[48]. The composition of higher trophic levels in the Arctic Ocean varies with region (Atlantic side vs. Pacific side), and with the sea-ice cover. It remains relatively stable, because the salinity effect on density is bigger than the temperature effect. Arctic region map with countries, national borders, rivers and lakes. The mean extent of the Arctic sea ice has been continuously decreasing in the last decades, declining at a rate of currently 12.85% per decade since 1980 from the average winter value of 15,600,000 km2 (6,023,200 sq mi). Also, some of these areas listed in the table are located in the Atlantic Ocean. In large parts of the Arctic Ocean, the top layer (about 50 m [160 ft]) is of lower salinity and lower temperature than the rest. Also, there is Longyearbyen (78°13′12″N 15°39′00″E / 78.22000°N 15.65000°E / 78.22000; 15.65000 (Longyearbyen)) on Svalbard, a Norwegian archipelago, next to Fram Strait. amzn_assoc_enable_interest_ads = "true"; Find arctic ocean map stock images in HD and millions of other royalty-free stock photos, illustrations and vectors in the Shutterstock collection. 1129x1418 / 733 Kb Go to Map. [60] In ice-covered regions of the central Arctic Ocean, polar cod is a central predator of primary consumers. 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]). [50][51][52] The surface waters of the northernmost[53] Arctic Ocean warmed, seasonally at least, enough to support tropical lifeforms (the dinoflagellates Apectodinium augustum) requiring surface temperatures of over 22 °C (72 °F). Large detailed map of Arctic Ocean. [64], As the extent of sea ice diminishes and sea level rises, the effect of storms such as the Great Arctic Cyclone of 2012 on open water increases, as does possible salt-water damage to vegetation on shore at locations such as the Mackenzie's river delta as stronger storm surges become more likely. Countries bordering the Arctic Ocean are: Russia, Norway, Iceland, Greenland (territory of the Kingdom of Denmark), Canada and the United States. [37] Atlantic Water has the same salinity as Arctic Bottom Water but is much warmer (up to 3 °C [37 °F]). [54], Currently, the Arctic region is warming twice as fast as the rest of the planet.[55][56]. [49] In the winter the relatively warm ocean water exerts a moderating influence, even when covered by ice. 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]). english labeling and scaling. 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. [78][79], "Arctic Sea" redirects here. amzn_assoc_region = "US"; ACEX drilling shed some light on the Lomonosov Ridge, which appears to be continental crust separated from the Barents-Kara Shelf in the Paleocene and then starved of sediment. The area has a fragile ecosystem, and it is especially exposed to climate change, because it warms faster than the rest of the world. London, 16 July 2020 – Details of a new depth map of the Arctic Ocean have been published in the Nature Journal Scientific Data.The new portrayal of the Arctic Ocean floor is in the form of a digital gridded database and comprises Version 4.0 of the International Bathymetric Chart of the Arctic Ocean (). Arctic Ocean political map. A new depth map of the Arctic Ocean has been unveiled in the form of a digital gridded database. Details of a new depth map of the Arctic Ocean have been published in the Nature Journal Scientific Data. This is the highest volumetric inflow to the Arctic Ocean, equalling about 10 times that of the Pacific inflow, and it creates the Arctic Ocean Boundary Current. [37] When water reaches the basin it is pushed by strong winds into a large circular current called the Beaufort Gyre. The low shifts to center over the North Pole in the summer. Disclosure: This trip was sponsored by Mazda of which I created a highlight video to share my once-in-a-lifetime journey. Physical Arctic Ocean Map. [38], Much of the Arctic Ocean is covered by sea ice that varies in extent and thickness seasonally. “The new cartography has a volume with a higher and better resolution data than the previous versions, and it includes marine regions which were unknown to date. The whole area is subject to international territorial claims. amzn_assoc_default_category = "All"; In general terms it includes Baffin Bay, Barents Sea Beauford Sea Chukchi Sea, East Siberian Sea, Greenland Sea, Hudson Bay,Kara Sea, Laptev Sea, White Sea and other tributary bodies of water. It’s impossible to see anything in any direction. The Gakkel Ridge rift is also poorly understand and may extend into the Laptev Sea.[35][36]. amzn_assoc_linkid = "f050dc3bdcb4e8360076d2fc7d2f7cc9"; The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes;[4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. This outflow is about 9 Sv.

In addition, there is a sea level pressure (SLP) ridge over Greenland that drives strong northerly winds through the Fram Strait, facilitating ice export. These variations in the Arctic all contribute to ice drift reaching its weakest point during the summer months. [9], For much of European history, the north polar regions remained largely unexplored and their geography conjectural. Despite when it peaks, we can not forget that alarmists claimed Arctic Ocean completely ice-free by 2013 and today we are in 2018, with an Ocean … The bottom of the Arctic Ocean has been in the news this week, with the US finally giving Shell permission to drill oil from its depths, and Russia submitting an updated territorial claim that states it owns an additional 1.2 square kilometres of seabed near the North Pole - some of which Denmark and Canada already assert ownership of. Of these three, the Siberian Shelf is the largest such shelf in the world. - Buy this stock vector and explore similar vectors at Adobe Stock Arctic Ocean Circulation: Going Around at the Top of the World. The mists soon close in around us and the clarity of the sky and the scenery has completely vanished. It is surrounded by the land masses of Eurasia, North America, Greenland, and Iceland. The gridded compilation has been completed under the auspices of the Regional Center for the […] The Arctic Ocean lies in the norht polar regions of the Eurth, it is surrounded by Eurasia and North America. There is also evidence that the drift is associated with the phase of the Arctic Oscillation and Atlantic Multidecadal Oscillation. In fact, this water mass is actually warmer than the surface water, and remains submerged only due to the role of salinity in density. Additional spreading helped to create the "triple-junction" of the Alpha-Mendeleev Ridge in the Late Cretaceous. Northwest Passage - Northern Sea Route: Map showing the geographic extent of the Arctic Ocean (as a darker blue tint). [37] As it is entrained, it cools and acts a heat shield for the surface layer. The two major basins are further subdivided by ridges into the Canada Basin (between Alaska/Canada and the Alpha Ridge), Makarov Basin (between the Alpha and Lomonosov Ridges), Amundsen Basin (between Lomonosov and Gakkel ridges), and Nansen Basin (between the Gakkel Ridge and the continental shelf that includes the Franz Josef Land). Icebergs are not sea ice but may become embedded in the pack ice. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. Where Is The Arctic Ocean On A Map. 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. [38] During the summer, this area of high pressure is pushed out closer to its Siberian and Canadian sides. Arctic Ocean map with North Pole and Arctic Circle. [70][71], Sea ice, and the cold conditions it sustains, serves to stabilize methane deposits on and near the shoreline,[72] preventing the clathrate breaking down and outgassing methane into the atmosphere, causing further warming. 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. The map location is at 5:32. [68], Global warming has increased encounters between polar bears and humans. Map without sea ice. arctic region map with countries, national borders, rivers and lakes. [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.
