楚科奇海, or the Chukchi Sea, is a marginal sea located in the Arctic Ocean, bordered by Russia to the west and Alaska to the east. It is named after the Chukchi people, an indigenous group living in the region. The sea is known for its cold waters and ice cover, especially during the winter months. The Chukchi Sea plays a significant role in the Arctic ecosystem, supporting various marine life, including walruses, seals, and polar bears. It is also an important area for fishing and has potential for oil and gas exploration, making it a focus of environmental and economic interest.
