Melting sea ice is gradually making the Arctic Ocean accessible to economic development. Does the Atlantic Ocean have the world’s deepest water? Polar bears rely on sea ice to access the seals that are their primary source of food as well as to rest and breed. WWF is working with governments, businesses, and communities to help preserve the region’s rich biodiversity. The deepest place on Earth, known as Challenger Deep, extends to a depth of more than 11,000 meters (36,000 feet) and is found in the Mariana Trench, in the Pacific. The recorded deepest point of Arctic Ocean is 5450 meters which is found in the Eurasian Basin. 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. Just how deep does the ocean go? 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 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. 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 deepest point is in the Eurasian Basin, at 5,450 m (17,900 ft). With on-the-ground teams in all of the Arctic countries, WWF is uniquely positioned to work with all member states, and has engaged with the Arctic Council since before its evolution.. 2. Home to an array of species—from polar bears to whales—the Arctic faces threats from oil and gas development and a changing climate. The coastline is 45,390 km (28,200 mi) long. A primary distinction can be made between the upper deep water, less saline than 34.92 to 34.93, which may derive rather directly from the Greenland or Norwegian Sea, and the lower deep water, which has had its … This is changing, however, because the Arctic may exhibit a strong response to global change and may be capable of initiating dramatic climatic changes through alterations induced in the oceanic thermohaline circulation by its cold, southward-moving currents or through its effects on the global albedo resulting from changes in its total ice cover. 6. Many Arctic residents are indigenous people who have adapted to live in one of the harshest environments in the world. 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. Scientists have discovered a new type of chlamydia species deep in the Arctic Ocean. It is clear from aeromagnetic and seismic data that the Eurasia Basin was formed by seafloor spreading along the axis of the Nansen-Gakkel Ridge. At high latitudes in the Arctic during the depths of winter, the Sun stays below the horizon for 24 hours. Unfortunately, none of the available seafloor cores have sampled sediments from the time interval between 35 to 3 million years ago. These points are much deeper than the majority of the ocean, which has an average depth of only 3,406 feet. Arctic Ocean, smallest of the world’s oceans, centring approximately on the North Pole. Ocean Conservancy teamed up with the Marine Exchange of Alaska to produce a short report to describe how advances in navigation and communications technologies can help enhance shipping safety and environmental protection in the U.S. Arctic. It is slightly over 5 million miles in area, and is around 12,000 feet deep. From astronomical observations, the Greeks theorized that north of the Arctic Circle there must be a midnight sun at midsummer and continual darkness at midwinter. Articles from Britannica Encyclopedias for elementary and high school students. Deepest known point is Molloy Deep at 5 557 m in the Fram Strait between Svalbard and Greenland. What species live in the Arctic?The diversity of the landscape of the Arctic means a wide array of wildlife. The origin of the Amerasia Basin is far less clear. Due to climate changes, summer Arctic ice cover is diminishing, and scientists therefore believe it is vitally important to get a better understanding of this environment and what impact future changes might bring to our world. Speak up for species and places through WWF's Action Center. The ocean is connected to the Pacific Ocean by the Bering Strait and the Atlantic Ocean by the Greenland Sea. Those are from deep to shallow Arctic Deep Water, Atlantic Water, and Arctic Surface Water. Arctic ocean may be the shallowest ocean out of five, but it holds importance that only it and none other ocean possess. An icebreaker or a nuclear-powered submarine can use the Northwest Passage through the Arctic Ocean to go between the Pacific and Atlantic oceans. The deepest reaches of the Arctic Ocean contain one of the most desolate environments on our entire planet. At just over 14 million square kilometres, the Arctic Ocean is the smallest and shallowest of the world’s oceans. Such speculations provided incentives for adventurous men to risk the hazards of severe climate and fear of the unknown to further geographic knowledge and national and personal prosperity. ... and it is circulated through mixing into the deep ocean… Deepest Point in the Arctic Ocean Eurasia Basin: 17,881 feet / 5450 meters Scientists have discovered a new type of chlamydia species deep in the Arctic Ocean.
