Sensational climate research in the Arctic: longest climate archive of the terrestrial Arctic retrieved

[02. June 2009] 

An international team of researchers from Russia, Germany, the USA and Austria has conducted a deep drilling program in the far northeast of Russia during the last six months to retrieve several hundred meters of lake sediments, impact breccias and permanently frozen soil. These make new insights into the climate history of the Arctic, crater formation of Lake El’gygytgyn and permafrost dynamics possible. A milestone has been reached at the beginning of May with the first results of the drilling campaign. The cores gained will help to answer crucial open questions of Arctic geology.

Rising permafrost temperatures raise emission of the climate gas methane

[30. March 2009] 

Bremerhaven, March 30th 2009. Higher temperatures in Arctic permafrost soils alter the community of methane generating microorganisms and lead to an increased emission of methane. Microbiologists from the Alfred Wegener Institute come to this conclusion in the current issue of the periodical “Environmental Microbiology”. The researchers were able to examine permafrost from the ground of the Leptev Sea, a shallow shelf sea close to the coast of Siberia, for the first time.
