description Lena River Delta Overview

Lena River Delta is a broad Arctic wetland in northern Russia where the Lena River enters the Laptev Sea. The river, which runs for roughly 4,400 kilometers, has built a delta of branching channels, islands, tundra, and permafrost. Much of the area is protected within the Lena Delta Wildlife Reserve, which provides habitat and breeding grounds for birds and other Siberian wildlife. The delta is used in studies of Arctic hydrology, sediment transport, wetlands, and climate change.
