Jäämeri

Jäämeri, also known as the Arctic Ocean, is the smallest and shallowest of the world's five major oceans. It is located in the Northern Hemisphere and is almost entirely surrounded by Eurasia and North America. The Jäämeri is characterized by its ice cover, which varies seasonally but is present year-round in many areas. Its waters are cold, with temperatures generally below freezing in the winter and only slightly above in the summer.

The Jäämeri plays a crucial role in global climate regulation. Its ice albedo effect, where the white ice reflects solar radiation back into space, helps to keep the planet cool. Changes in Jäämeri ice cover have significant implications for weather patterns and sea levels worldwide. The ocean is also a vital habitat for a unique array of flora and fauna, including polar bears, seals, whales, and various fish species, many of which are adapted to its extreme conditions.

Historically, the Jäämeri was largely inaccessible due to its ice. However, with warming global temperatures, the extent and thickness of its ice have been diminishing, opening up new shipping routes and increasing interest in the region's natural resources, such as oil and gas. This has led to geopolitical considerations and challenges related to environmental protection and sustainable development in the Jäämeri region.
