An expedition lead by AWI jointly carried out with partners from GFZ Potsdam (Helmholtz-Zentrum Potsdam – Deutsches GeoForschungsZentrum), Hydrobase Tiksi, IPGG Novosibirsk (Trofimuk Institute of Petroleum Geology and Geophysics), MPI Yakutsk (Melnikov Permafrost Institute), and NEFU (North-Eastern Federal University Yakutsk).
Duration: Four Weeks.
Goals: Exposed to subaquatic conditions, permafrost thaw occurs exponentially and the associated extent of taliks and alterations of biogeochemical gradients are difficult to predict. Also during winter unfrozen Zones in the permafrost areas are suggested to function as nutritious tanks for microbial activity and hence promote the production and release of methane and carbon dioxide. This drilling campaign aimed to retrieve frozen and unfrozen sediment cores, ice cores as well as geophysical data from Bykovsky Peninsula to cover several scientific disciplines including geomicrobilogy, geocryology, geophysics and geochemistry.
