At just over 14 million square kilometres, the Arctic Ocean is the smallest and shallowest of the world’s oceans. Alaska alone is estimated to have more than 100,000 glaciers. The region does not experience much fluctuation throughout the year in terms of temperature, and temperatures during the long winter months remain very cold but stable. Even a slight shift in temperature could potentially result in an ice-free Arctic within this century. The sediments of the Arctic Ocean floor record the natural of the physical environment, climate, and ecosystems on time scales determined by the ability to sample them through coring and at resolutions determined by the rates of deposition. Around most of the globe, the surface ocean is warmed by the sun and loses freshwater through evaporation, making it warmer and saltier than the waters below. Assistant Administrator for Oceanic and Atmospheric Research, National Oceanic and Atmospheric Administration, U.S. Department of Commerce, Rockville, Maryland, 1990–96. 3 3. continental shelf. The Molloy Deep (also known as the Molloy Hole) is a bathymetric feature in the Fram Strait, within the Greenland Sea east of Greenland and about 160 km west of Svalbard.It is the location of the deepest point in the Arctic Ocean. For marine life, the Arctic Ocean is a unique place to live. The deepest point is in the Eurasian Basin, at 5,450 m (17,900 ft). Litke Deep at 5 309 m is in the Arctic Ocean, was previous estimated to be 5 450, and the deepest spot know until Molloy Deep was found. The ocean is connected to the Pacific Ocean by the Bering Strait and the Atlantic Ocean by the Greenland Sea. This has caused the North Atlantic to become fresher over the past several decades and has caused the currents to slow. Deep-sea dump: Trash is collecting on the Arctic seafloor One part of the ocean floor has 20 times more litter than a decade ago A piece of blue plastic litter rests in the branches of a sea sponge. The Arctic ice cap is a shifting pack of sea ice some 6.5 to 10 feet i.e. The Arctic Ocean has played a minor role in world history. Since shrinking sea ice forces polar bears to spend more time on land, people and bears can come into conflict. What threats do polar bears face?Climate change is an enormous threat to polar bears. The tectonic history of the Arctic Basin in the Cenozoic Era (i.e., about the past 65 million years) is largely known from available geophysical data. Ice cover … 3. Hydrothermal vents have been found all over the ocean, including regions of the Pacific, Atlantic, Indian, Southern and Arctic oceans. During the summer months, the sun shines up to 24 hours a day. The Arctic Ocean and its marginal seas—the Chukchi, East Siberian, Laptev, Kara, Barents, White, Greenland, and Beaufort and, according to some oceanographers, also the Bering and Norwegian seas—are the least-known basins and bodies of water in the world ocean as a result of their remoteness, hostile weather, and perennial or seasonal ice cover. 8. With less sea ice every year, polar bears and many other ice-dependent creatures are at risk. As nice as it is to hear that the Arctic benthos may be benefitting from the loss of sea ice, further study is required to say whether or not this is the case on a larger scale. The freezing point of salt water is 28.8 °F, and the waters below the surface of the ice remain just above this temperature. A glacier can range in length from the equivalent of a football field to more than 100 miles. Our vision is a world powered by renewable energy, where communities and ecosystems are resilient in the face of climate changes. They are a filter-feeder shark that cruises through the ocean at low speeds filtering zooplankton along their tiny teeth. Ice coverage in the Arctic Ocean is currently the highest it has been since 2010 with support from the strongest polar vortex on record. A whopping 94% of all life-forms on Earth are aquatic. Dr. Kirstin Thompson is among those using new technologies to identify species roaming the frigid northern waters. These points are much deeper than the majority of the ocean, which has an average depth of only 3,406 feet. Donations are tax-deductible as allowed by law. The Arctic is also a rich habitat for wildlife and contains vast resources like enormous freshwater reserves, fossil fuels, and fisheries. Arctic Ocean - Arctic Ocean - Sea ice: The cover of sea ice suppresses wind stress and wind mixing, reflects a large proportion of incoming solar radiation, imposes an upper limit on the surface temperature, and impedes evaporation. Deepest known point is Molloy Deep at 5 557 m in the Fram Strait between Svalbard and Greenland. International New York Times, Nov 27 … 2 to 3 meters thick – floating above the 13,000-foot-deep (4,000-meter-deep) Arctic Ocean. Deep frozen arctic microbes are waking up Globally, glacier melt rates have nearly doubled in the last five years. This section describes the Arctic Ocean and its marginal seas, discusses the physical characteristics and origin of the ocean floor, and outlines what is known about its physical oceanography and sea ice dynamics. The coastline is 45,390 km (28,200 mi) long. (David Goldman/AP) By . The stratification is typified by a low-salinity surface mixed layer (as much as 50 m deep) over cold saline water, underlain by warmer salty Atlantic water down to about 1600 m, with deep water beneath (Carmack, 2000). continental shelf. The focus of spreading began under the edge of the Asian continent, from which a narrow splinter of its northern continental margin was separated and translated northward to form the present Lomonosov Ridge. The deepest sounding obtained in Arctic waters is 18,050 feet (5,502 metres), but the average depth is only 3,240 feet (987 metres). It separates the Atlantic Ocean into two large troughs each of which with a depth ranging from 12,100-18,000 ft (3,700-5,500 metres). The Arctic Ocean, and sea ice . Omissions? The basin floor measures about 220 … How big is the Arctic Ocean?The Arctic Ocean is about 5.4 million square miles—about 1.5 times as big as the US—but it is the world’s smallest ocean.

The trench is 1,554 miles long and 44 miles wide, or 120 times larger than the Grand Canyon. Data from 1950 to 2010 show that since the 1970s the temperature of the Atlantic water has been steadily warming. The deepest point is in the Eurasian Basin, at 5,450 m (17,881 ft). The enlightened view was that both the northern and southern polar regions were uninhabitable frozen wastes, whereas the more popular belief was that there was a halcyon land beyond the north wind where the sun always shone and people called Hyperboreans led a peaceful life. Many Arctic residents are indigenous people who have adapted to live in one of the harshest environments in the world. The floor of the Arctic Ocean is divided into 2 basins and 4 sub-basins by 3 submarine ridges: the Alpha, the Gakkel, and the Lomonosov. Yes, Arctic Ocean contains some amount of radioactive as well as the other oceans. It is the location of the deepest point in the Arctic Ocean. Wind and water stresses keep the ice pack in almost continuous motion, causing the formation of cracks (leads), open ponds (polynya), and pressure ridges. Of the hundreds of sediment corings taken, only four penetrate deeply enough to predate the onset of cold climatic conditions. Melting sea ice is gradually making the Arctic Ocean accessible to economic development. The melting ice causes freshwater to be added to the seawater in the Arctic Ocean which flows into the North Atlantic. The Arctic Ocean may be the world's smallest, but it's becoming a critical region as climate change warms it more quickly than anywhere else on Earth. Arlis II (USA, 1963), Lorex (Canada, 1979), Arctic Ocean (1991, 1996, 1998 and 2001) with the ice breakers Polarster (Germany) and Oden (Sweden). The Arctic story is a tale of sweeping geologic change catalyzing a sweeping geopolitical contest. The Arctic Ocean is covered in masses of sea ice during most of the year, which can sometimes be hundreds of feet thick. It is known as Loki’s Castle, a large field of hydrothermal vents on the sea floor that’s extremely low in oxygen and high in pressure — and a very difficult place for any organisms to survive. Home to an array of species—from polar bears to whales—the Arctic faces threats from oil and gas development and a changing climate. Washington, DC 20037. The Atlantic water makes its way throughout the Arctic Ocean: The bathymetry of the deep Arctic basin margins and ridges guides the water as it travels counterclockwise and deeper in the basin. It is the coldest ocean on Earth and is often capped with sea ice. The Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 km (5,427,000 sq mi), almost the size of Antarctica. Climate 25, 8362 (2012).
