The groundwater monitoring is used to evaluate the local quality and quantity of the groundwater. These information are required to obtain important insights in the hydrochemical processes in the aquifer, as well as the origin and residence time of groundwater.
The Grundfos MP 1 submersible pump set with a connected, closed flow cell enables observations of the physicochemical parameters with digital IDS sensors (temperature, pH, electrical conductivity, redox potential, dissolved oxygen), …

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 the laboratory for fluid chemistry, various devices are used to determine the chemical properties of geothermal fluids.

In the laboratory for fluid physics, various devices are used to determine the properties of geothermal fluids: density, viscosity, electrical conductivity, thermal conductivity, heat capacity, sonic velocity.

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.
