Pollution in the Arctic Ocean Pollution in the Arctic Ocean Pollution in the Arctic Ocean is primarily the result of economic activities carried out on land – such as 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 world. However, the Arctic Ocean remains relatively clean compared to other marine regions of the world. Economic activity in the Arctic seas is not the only source of pollution. The growing presence of military weapons systems in the region raises concerns of increased pollution. Management of
Ocean area and volume – are defined in part by the continents, various archipelagos, and other criteria. Oceans are fringed by smaller, adjoining bodies of water such as seas, gulfs, bays, bights, and straits. The mid-ocean ridges of the world are connected and form a single global mid-oceanic ridge system that is part of every ocean and the longest mountain range in the world. The continuous mountain range is long (several times longer than the Andes, the longest continental mountain range). The total mass of the hydrosphere is about 1.4 quintillion metric tons ( long tons or short tons), which is
