The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans.
Pollution in the Arctic Ocean is primarily the result of economic activities carried out on land, which is sources from locally, regionally, and globally origins. [1] There is also the inclusion of industrial development in the Arctic region, northern rivers, and the effects of military activities, particularly nuclear activity – as well as the influx of pollutants from other regions of the ...
However, the vast majority of the Arctic known to contain gas and oil resources is already within uncontested EEZs. While these EEZs leave much of the Central Arctic Ocean high seas, Canada, Russia, Denmark (via Greenland), and Norway have all announced extended continental shelf claims that cover almost the entire Arctic seabed.

The Arctic has already lost about half of its sea ice, compared to the 1980s at the end of the summer. It is known that more warming has delayed ice formation, and resulted in thinner sea ice growth.
Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
The first ice-free days of the Arctic Ocean could occur as soon as the 2020s or 2030s — as many as 10 years earlier than previous projections.
The Arctic Ocean is expected to see its first ice-free events in the near future - most likely before 2050, and potentially in the late 2020s or early 2030s. [10] This would have no precedent in the last 700,000 years.
The North American Arctic is composed of the northern polar regions of Alaska (USA), Northern Canada and Greenland. [1] Major bodies of water include the Arctic Ocean, Hudson Bay, the Gulf of Alaska and North Atlantic Ocean. [2] The North American Arctic lies above the Arctic Circle. [3] It is part of the Arctic, which is the northernmost ...
