The Chukchi Sea is a marginal sea located in the Arctic Ocean, bordered by the northeastern coast of Russia and the northwestern coast of Alaska, USA. It is named after the Chukchi people, an indigenous group living in the region. The sea is characterized by its cold temperatures and seasonal sea ice, which significantly influences the local climate and ecosystems. This sea plays a crucial role in marine biodiversity, supporting various species such as seals, walruses, and polar bears. It is also an important area for migratory birds and fish, including species like the Arctic cod. The Chukchi Sea is vital for local communities, providing resources and opportunities for traditional hunting and fishing.
