jäämere

Jäämere is the Finnish word for Arctic Ocean. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It is also the coldest, with its surface waters typically remaining below freezing point. Much of the Arctic Ocean is covered by sea ice, although the extent and thickness of this ice have been significantly decreasing in recent decades due to climate change.

The Arctic Ocean is located in the Northern Hemisphere and surrounds the North Pole. It is bordered by Eurasia and North America. Major seas connected to the Arctic Ocean include the Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, Chukchi Sea, Beaufort Sea, and Greenland Sea. The ocean's geography is characterized by a central basin, surrounded by continental shelves.

The Arctic Ocean plays a crucial role in global climate regulation. Its ice cover reflects solar radiation, helping to cool the planet. Changes in Arctic sea ice have far-reaching consequences for weather patterns and sea levels worldwide. The region is also rich in natural resources, including oil, gas, and minerals, which are becoming increasingly accessible as the ice recedes. This accessibility has led to growing geopolitical interest and potential for increased shipping routes.
