The Northern Sea, also known as the Barents Sea, is a marginal sea located in the Arctic region, bordered by Norway to the west and Russia to the east. It is part of the larger Arctic Ocean and is characterized by its cold waters and ice coverage, especially during winter months. The sea is rich in marine life, including fish species like cod and haddock, making it an important area for fishing. The Northern Sea plays a significant role in regional climate and ecology. It serves as a crucial habitat for various wildlife, including seals and polar bears. Additionally, the sea is a key route for shipping and transportation, particularly as climate change leads to reduced ice cover, opening new navigation paths in the Arctic.
