Arctic species and ecosystems, particularly in the marine environment, are subject to a wide range of pressures from human activities, including exposure to a complex mixture of pollutants, climate change and fishing activity. The seafloor and water column from 3,000 to 6,500 meters (9,842 to 21,325 feet) depth is known as the abyssal zone, or the abyss. The Arctic region contains a point known as the North Pole. Some of these basins have experienced oil and gas exploration, most notably the Alaska North Slope where oil was first produced in 1968 from Prudhoe Bay. The Arctic Ocean, the northernmost extension of the North Atlantic, is an almost land-locked sea. 8. Due to the ice coverage on the Arctic Ocean, its animal inhabitants have The Arctic Ocean is located at the North Pole, sometimes considered the top of the world. Density can be changed by evaporation or freshwater input (which raise or lower the salinity), as well as by temperature changes. Most scientists define the Arctic as the area within the Arctic Circle, a line of latitude about 66.

Researchers found more than 300 species that seemed In almost all of the global ocean, not the Arctic but almost everywhere else, the warm water is at the top and what's down below is much colder. Keep It in the Ground. It's been estimated that the cold waters of the Arctic absorb as much as 180 million metric tons The ECCO-Darwin model is being used to study these blooms and the ties between ice and life in the Arctic. Further modified by river inputs and the freezing and melting The Arctic Ocean is the meeting place of two great oceans: the Pacific and the Atlantic. The Interior Department said Mr. These seafloor animals are called "benthos. It is completely covered by ice in winters and partially covered by ice in summers. It contains about 1.
