Polygon Tundra, Lena Delta

Polygon Lakes in the Arctic Tundra are unique to permafrost areas and form as a result of the freeze-thaw cycle that occurs here. With a layer of frozen earth below, water becomes trapped in pools on the surface. The amount of carbon (Greenhouse Gases) stored within the upper layers of this frozen permafrost earth is more than is currently contained in the Earth's Atmosphere. (UNEP).
