The ISOLAB FACILITY of the AWI in Potsdam develops and utilizes stable H, O, C, N isotope methods to decipher Quaternary environmental change on in polar regions of both hemispheres.
The Laboratory for Stable Isotopes at AWI Potsdam does research in the Polar Regions of both hemispheres on natural materials such as water, ice, organic matter form soils and sediments and biogenic opal (i.e. diatoms). We use analyses on stable oxygen, hydrogen, carbon and nitrogen isotopes to reconstruct the climate and environmental dynamics in high latitudes (both Arctic and Antarctic research).
The research focus region is Siberia. The scientific orientation of research projects imcludes scientific applications of stable isotope methods in permafrost research, palaeoclimate studies, by also in the fields of limnology, hydrology, ecology and glaciology.

The Iso-Arc project, which was funded by the AWI Strategy Fund, aims for the first-time detailed determination and description of the water cycle in the Eastern Arctic and its isotope fingerprint (H218O, HD16O). Isotope measurements of water vapor are analyzed and interpreted in combination with ocean and precipitation data and climate simulations with explicit isotope diagnostics.
The subproject of the BMBF project "PLOT - Paleolimnological Transect" that ist carried out at the University of Cologne focuses on the reconstruction of climate and vegetation changes along a 6000 km long latitudinal transect from Lake Ladoga in the west to Lake El´gygytgyn in the East (see map). The reconstruction is based on multi-disciplinary geoscientific analyses of more than 50 m long sediment cores from five lakes, which are to be compared to respective data from the master record that was drilled in 2009 within the scope of the El´gygytgyn Drilling Project. The subproject at the University of Cologne furthermore is responsible for the coordination of the German activities in the Russian-German PLOT project, which is carried out under the umbrella of a bilateral agreement of the Russian and German research ministries on scientific collaboration in the fields of polar and marine research.
