Permafrost Carbon and Nitrogen Lab (CarLa) focuses its efforts on the characterization of carbon and nitrogen vulnerability in thawing permafrost as well as carbon and nitrogen quantification and paleo-environmental reconstruction. The following parameters are recorded: bulk total carbon and nitrogen, total organic carbon and lipid biomarkers.

The hydrochemistry lab at AWI provides wet chemistry analyses of surface and ground waters, snow, ice and permafrost pore water samples. We have optimized the workflow for thawing samples and extracting pore water sediment from sediments and soils for further analysis. We analyze concentrations of major dissolved species in cationic, anionic and total dissolved form, and perform analyses of organic carbon. Standard parameters, such as pH, alkalinity and electrical conductivity of samples are …
