Pingos are spectacular landforms associated with permafrost in the Arctic. They are circular or elliptical formations protruding from the level ground of the tundra, and can be up to 60 meters high. In essence, they are huge lumps of ice covered with soil. Similar structures are now found strewn on the ocean floor in the Arctic shallow seas.
A recent study by Pavel Serov, PhD at Center for Arctic Gas Hydrate, Environment and Climate (CAGE), describes for the first time pingo like features offshore Siberia. The study suggests that they are forming because of the thawing of the subsea permafrost, and was published in Journal of Geophysical Research.
