The Laptev Sea is a marginal sea located in the Arctic Ocean, bordered by Siberia to the south and the New Siberian Islands to the north. It covers an area of approximately 672,000 square kilometers and is known for its cold waters and seasonal sea ice. The sea plays a crucial role in the Arctic ecosystem and is part of the larger East Siberian Sea. The Laptev Sea is fed by several major rivers, including the Lena River, which contributes significant freshwater. This sea is also important for marine life, supporting various species of fish and seabirds. Additionally, it is a region of interest for climate research due to its sensitivity to global warming.
