While determining the age of a permafrost layer in Siberia, an international team of experts set a new record: at its deepest point, the soil is at least 650,000 years old. Yet the team’s

However, since the permafrost stores huge quantities of carbon, which is released in the [...] thawing will further worsen global warming. In order to collect reliable, up-to-date information on permafrost thawing, the joint project UndercoverEisAgenten was launched today.

In the future, his findings could help provide a more realistic picture of permafrost thawing.

Helmholtz Centre for Polar and Marine Research (AWI) in Potsdam contribute with a factsheet on permafrost soils.

Wednesday afternoon we visited Miriam’s old Kenai-permafrost research site. After a 45 minute drive to the interior of the peninsula, we arrived at a small permafrost peat plateau covered by black spruce and [...] protected permafrost originates from the younger Dryas and was protected by the peat layer. The peat formed, froze and expanded and therefore rose above the wetland level forming these permafrost remnants [...] remnants above the wetlands. Meanwhile, this site is heavily affected by thawing permafrost, too and undergoes rapid degradation. Corona safe group photograph with Miriam on the left side Matthias and Miriam
