The Arctic Weather Map below shows the weather forecast for the next 12 days. Published in digital format, the new chart expands up to 19.6% the submarine surface mapped in previous versions. Scientific settlements were established on the drift ice and carried thousands of kilometers by ice floes.[12]. 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. 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". The reasons individuals pick the Arctic Ocean as their perfect vacation vary extensively. The International Hydrographic Organization (IHO) defines the limits of the Arctic Ocean (excluding the seas it contains) as follows:: Art. Save Comp. However, meals can be a few days apart or even a few months. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere, and extends south to about 60°N. [13][14] The coastline is 45,390 km (28,200 mi) long. 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. In England and other European nations, the myth of an "Open Polar Sea" was persistent. Harry and the pilot of the other plane are flying on GPS. The summer shrinking of the ice has been quoted at 50%. The Arctic Ocean is a body of water between Europe, Asia, and North America, mostly north of the Arctic Circle. Full size. Reduced sea ice due to melting is causing polar bears to search for new sources of food. [37] Atlantic Water has the same salinity as Arctic Bottom Water but is much warmer (up to 3 °C [37 °F]). This map was created by a user. 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. Retrieved 18 November 2013. It is generally necessary that the upper 100–150 m (330–490 ft) of ocean water cools to the freezing point for sea ice to form. 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. 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.. 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. I phone back, collect again, and Harry Hansen is there waiting for my call. The temperature of the surface water of the Arctic Ocean is fairly constant at approximately −1.8 °C (28.8 °F), near the freezing point of seawater. It occupies a roughly circular basin and covers an area of about 14,056,000 km2 (5,427,000 sq mi), almost the size of Russia. In September 2012, the Arctic ice extent reached a new record minimum. Additional spreading helped to create the "triple-junction" of the Alpha-Mendeleev Ridge in the Late Cretaceous. [16] Before the advent of modern icebreakers, ships sailing the Arctic Ocean risked being trapped or crushed by sea ice (although the Baychimo drifted through the Arctic Ocean untended for decades despite these hazards). The Dorset were the last major Paleo-Eskimo culture in the Arctic before the migration east from present-day Alaska of the Thule, the ancestors of the modern Inuit. The Northwest Passage and Northern Sea Route are two important seasonal waterways that connect the Atlantic and Pacific Oceans. [1] It is also known as the coldest of all the oceans. The map below shows the regional seas that make up the Arctic Ocean, along with other geographical features. “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. Cyclones are more frequent in summer and may bring rain or snow. Arctic Ocean map with North Pole and Arctic Circle. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. english labeling and scaling. 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 … Before the advent of modern icebreakers, ships sailing the Arctic Ocean risked being trapped or crushed by sea ice. [37] Pacific water also exits along the west coast of Greenland and the Hudson Strait (1–2 Sv), providing nutrients to the Canadian Archipelago. It includes Baffin Bay, Barents Sea, Beaufort Sea, Chukchi Sea, East Siberian Sea, Greenland Sea, Hudson Bay, Hudson Strait, Kara Sea, Laptev Sea, Northwest Passage, and other tributary water bodies. Endangered marine species in the Arctic Ocean include walruses and whales. The ocean is virtually icelocked from October to June, and the superstructure of ships are subject to icing from October to May. The low shifts to center over the North Pole in the summer.

The mists soon close in around us and the clarity of the sky and the scenery has completely vanished. It is generally taken to include Baffin Bay, Barents Sea, Beaufort Sea, Chukchi Sea, East Siberian Sea, Greenland Sea, Iceland Sea, Norwegian Sea, Hudson Bay, Hudson Strait, Kara Sea, Laptev Sea, White Sea and other tributary bodies of water. Source: EEA The area includes many fjords with rivers flowing into them. [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. Winters are characterized by the polar night, extreme cold, frequent low-level temperature inversions, and stable weather conditions. [37] The Arctic Ocean has a total volume of 18.07×106 km3, equal to about 1.3% of the World Ocean. [72][73], Other environmental concerns relate to the radioactive contamination of the Arctic Ocean from, for example, Russian radioactive waste dump sites in the Kara Sea[74] Cold War nuclear test sites such as Novaya Zemlya,[75] Camp Century's contaminants in Greenland,[76] or radioactive contamination from Fukushima. At this time, falling sea levels allowed people to move across the Bering land bridge that joined Siberia to northwestern North America (Alaska), leading to the Settlement of the Americas. It is connected to the Pacific Ocean by the Bering Strait and to the Atlantic Ocean through the Greenland Sea and Labrador Sea. The maximum snow cover is in March or April — about 20 to 50 cm (7.9 to 19.7 in) over the frozen ocean. As temperatures cool dramatically in the winter, ice forms and intense vertical convection allows the water to become dense enough to sink below the warm saline water below. There is also evidence that the drift is associated with the phase of the Arctic Oscillation and Atlantic Multidecadal Oscillation. map without sea ice.

Rifting then extended northward, opening the Arctic Ocean as mafic oceanic crust material erupted out of a branch of Mid-Atlantic Ridge. Similar Illustrations See All. [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. 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. Canada's brand new all-season highway to the The speed of the ice drift is roughly 1–4 cm/s. 1129x1418 / 733 Kb Go to Map. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. The sea ice is affected by wind and ocean currents, which can move and rotate very large areas of ice. 17. [69] Beginning in December 2018 and coming to an apex in February 2019, a mass invasion of polar bears into the archipelago of Novaya Zemlya caused local authorities to declare a state of emergency. The few expeditions to penetrate much beyond the Arctic Circle in this era added only small islands, such as Novaya Zemlya (11th century) and Spitzbergen (1596), though since these were often surrounded by pack-ice, their northern limits were not so clear. Since 1937, Soviet and Russian manned drifting ice stations have extensively monitored the Arctic Ocean. Northwest Passage - Northern Sea Route: Map showing the geographic extent of the Arctic Ocean (as a darker blue tint). It may contain up to 10 billion barrels of oil. amzn_assoc_placement = "adunit0"; The area has a fragile ecosystem, and it is especially exposed to climate change, because it warms faster than the rest of the world. [9], For much of European history, the north polar regions remained largely unexplored and their geography conjectural. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. 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. The final defined water mass in the Arctic Ocean is called Arctic Surface Water and is found from 150–200 metres (490–660 feet). These primary consumers form an important link between the primary producers and higher trophic levels. [54], Currently, the Arctic region is warming twice as fast as the rest of the planet.[55][56]. The apex predators in the Arctic Ocean - Marine mammals such as seals, whales, and polar bears, prey upon fish. It has an average depth of 3,953 feet (1,205 m) and its deepest point is the Fram Basin at -15,305 feet (-4,665 m). This water is met by Greenland Sea Deep Water, which forms during the passage of winter storms. In World War II, the European region of the Arctic Ocean was heavily contested: the Allied commitment to resupply the Soviet Union via its northern ports was opposed by German naval and air forces. [62], The Arctic ice pack is thinning, and a seasonal hole in the ozone layer frequently occurs. Because of sea ice and remote conditions, the geology of the Arctic Ocean is still poorly explored. The gridded compilation has been completed under the auspices of the Regional Center for the […] Lion's mane jellyfish are abundant in the waters of the Arctic, and the banded gunnel is the only species of gunnel that lives in the ocean. The Arctic Ocean is an isolated mediterranean basin with only limited communication with the world’s oceans, principally the Atlantic Ocean via the Fram Strait and the Barents Sea, and the Pacific Ocean via the Bering Strait. The Arctic Ocean is a lot more sophisticated than the Arctic Land from Hungry Shark Evolution, as it has more unique prey, a bigger size, deep sea creatures, underwater currents, unique birds, and aquatic plants. 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]).
