The East Siberian Sea is a marginal sea located in the Arctic Ocean, bordered by the northeastern coast of Russia. It is situated between the Chukchi Sea to the east and the Laptev Sea to the west. The sea is characterized by its cold temperatures and seasonal sea ice, which significantly influences the local climate and ecosystem. This sea is home to various marine life, including fish and marine mammals like seals and whales. The East Siberian Sea also plays a role in global climate patterns and is of interest for potential natural resource exploration, including oil and gas reserves beneath its seabed.
