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 …

In this lab the soil physical and thermal properties of undisturbed and artificial samples (i.e. porosity, thermal and hydraulic conductivity) are analyzed. The applications comprise calibration, testing and quality control of meteorological and soil physical sensors for polar environments in long-term observations. The work done here serves as experimental bridge between field observations and numerical modelling; testing and unravelling complex physical processes.
