Most are found in the fjords of North Eastern Canada and Western Greenland. 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. It is an extension of the Icelandic Low, which creates cyclonic ocean circulation in this area. What’s here? Current plans to allow drilling in the Arctic Ocean could hurt the species even more. The fervent desire of European merchants for a northern passage, the Northern Sea Route or the Northwest Passage, to "Cathay" (China) caused water to win out, and by 1723 mapmakers such as Johann Homann featured an extensive "Oceanus Septentrionalis" at the northern edge of their charts. 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]). Arctic Aquatic Animals (Sea Animals) Narwhal. See our study on Fisheries. The bathymetry of the ocean bottom is marked by fault block ridges, abyssal plains, ocean deeps, and basins. [1] It is also known as the coldest of all the oceans. [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]. There is also evidence that the drift is associated with the phase of the Arctic Oscillation and Atlantic Multidecadal Oscillation. 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. It is connected to the Pacific Ocean by the Bering Strait and to the Atlantic Ocean through the Greenland Sea and Labrador Sea.[1]. 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 fact, the Arctic Ocean is only connected to other oceans via the Bering Strait (to the Pacific Ocean) and the Greenland and Labrador Seas (to the Atlantic Ocean). 55 million years ago during the Paleocene–Eocene Thermal Maximum, when global climate underwent a warming of approximately 5–8 Â°C (41–46 Â°F), the region reached an average annual temperature of 10–20 Â°C (50–68 Â°F). Marine Animals. 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. 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). At the same time, sediments shed off the rising Canadian Rockies building out the large Mackenzie Delta. The whole area is subject to international territorial claims. Winters are characterized by the polar night, extreme cold, frequent low-level temperature inversions, and stable weather conditions. A final example of seasonal pressure system movement is the low pressure system that exists over the Nordic and Barents Seas. [63] Reduction of the area of Arctic sea ice reduces the planet's average albedo, possibly resulting in global warming in a positive feedback mechanism. Despite the difficult climatic conditions present around the Arctic Ocean, it is home to a wide range of wildlife. During the Cretaceous the Canadian Basin opened and tectonic activity due to the assembly of Alaska caused hydrocarbons to migrate toward what is now Prudhoe Bay. Rifting then extended northward, opening the Arctic Ocean as mafic oceanic crust material erupted out of a branch of Mid-Atlantic Ridge. 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. These islands are home to a meteorological station and a Russian Navy base. [37] Pacific water also exits along the west coast of Greenland and the Hudson Strait (1–2 Sv), providing nutrients to the Canadian Archipelago. Between October and June, the ice cover over the Arctic Ocean is so dense that ships cannot pass. The overturning of this water plays a key role in global circulation and the moderation of climate. The low shifts to center over the North Pole in the summer. Fridtjof Nansen was the first to make a nautical crossing of the Arctic Ocean, in 1896. This basin is known as the Canada Basin. The average depth of the Arctic Ocean is 1,038 m (3,406 ft). [39] It flows slowly, at about 0.02 m/s. [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. Arctic marine fisheries … Retrieved 18 November 2013. The first surface crossing of the ocean was led by Wally Herbert in 1969, in a dog sled expedition from Alaska to Svalbard, with air support. The coldest, windiest place on Earth holds 60 percent of the fresh water on the planet. 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.
