Wet-Sedge-Polygons on Samoylov Island with Stolb Island in the Background

Polygonal structures characterise the Holocene river terrace found on Samoylov Island. The soils that develop within this unique landscape have very interesting properties. They are affected by different hydrologic situations with water saturated polygon centres and dry polygon rims. Since these soils are very organic rich and the permafrost is likely to continue to thaw, they play an important role for the global climate as a probable future source of trace gases.
