The Atlantic Ocean may be described as a bed of water with temperatures below 9°C (layer of cold water) supporting a water bubble over 9°C (layer of warm water), which extends from 50° latitude N 50°S latitude and has an average depth of That means at high latitudes sea ice can form. The surface area is 14, 750, 000 square kilometers, the volume is 18, 070, 000 cubic kilometers. Arctic Fisheries Since 2011, over 8 million metric tons have been harvested from Arctic waters each year for commercial, artisanal, subsistance, and recreational uses, after declining from its peak of 17 million tons in 1968.; Arctic Mineral Resources. Arctic Ocean is the smallest of all oceans. Water from the Atlantic is introduced into the Arctic by the Norwegian current that flows northeastward passing between Norway and Spitsbergen. The Arctic is mainly ocean covered by millions of square miles of sea ice most of the year. With a salinity level that ranges from anywhere between 33 to 37 parts per thousand, the Atlantic Ocean is the world’s saltiest sea.

Arctic Ocean average sea surface salinity is projected to decrease by 1.5 ± 1.1 psu (Shu et al. The Arctic Ocean is almost completely covered with ice for the majority of the year and its average temperature seldom rises above freezing. However, regions like the Mediterranean, the Atlantic, and the Bay of Bengal have higher salinity levels. Audience: This book will be of interest to researchers and scientists in oceanographic and climate research institutions, fisheries laboratories, arctic/polar institutions, climate change policy advisors. What does ocean mean? The extent was 14.42 million km2, 8% below the 1981-2010 average. The Arctic Ocean is the smallest of the world's five oceans with an area of 5,427,000 square miles (14,056,000 sq km). There are one file of yearly and pentadal vertical mean temperature anomaly and four files of 3-month vertical mean temperature anomaly per each depth layer for each of four major oceanic basins: the World Ocean, the Pacific Ocean, the Atlantic Ocean (which includes the entire Arctic Ocean), and the Indian Ocean. 7.4M people helped. This chart shows annual estimates for the first 2,000 meters of ocean depth. Satellite observations show that sea ice extent in the Arctic has been declining from 1979 through present day, reaching record minimum extents in 2007 and 2012. The Arctic was hit by higher-than-average temperatures in May and July 2019, which likely worsened the pace of summer sea ice melt, he says. Open water is dark blue, and land masses are gray. Arctic Ocean sea ice: In September 2011, sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Found insideThe sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. The average sastrugi depth varied from 23.0 to 35.4 cm. 1.347 × 10 9 km 3: Kennish, Michael J. The “Arctic Ocean mean” is just an average of all the complete annual cycles (August–July) measured at the NP stations. The central Arctic had an average snow depth on level ice of 21 cm, while it varied from 9.6 to 15.2 cm in the marginal seas. The reservoir of cold waters and ice that does not extend beyond the northern polar circle washes the shores of the continents of the hemisphere and Greenland from the north. The second shallowest ocean is the Atlantic, with an average depth of 12,254 feet. Fig. This affects heat transfer through and storage in sea ice, which may affect the mass balance of sea ice at a global scale. This is the central hypothesis of this work. The Arctic Ocean has the widest continental Genius.

Arctic temperatures continue to increase at double the rate of the global temperature increase. These points are much deeper than the majority of the ocean, which has an average depth of only 3,406 feet. The Arctic Ocean is unique in that nearly one-third of its total area is underlain by continental shelf, which is asymmetrically distributed around its circumference. The average depth of snow attached to ice ridges was in the range from 49.5 cm in the Chukchi Sea to 64.9 cm in the central Arctic. It occupies the most northern region of Earth. Living Resources.
