GeoBasis is operated by Department of Bioscience, Aarhus University in co-operation with Department of Geography and Geology, University of Copenhagen and Asiaq - Greenland Survey.

The objective of GeoBasis is to provide long term data of terrestrial variables describing the dynamics of the physical environment in Kobbefjord. Collected data will be used to improve current model predictions for future changes in the terrestrial ecosystem and to quantify the feedback mechanisms from the low arctic ecosystem to the climate.

The GeoBasis programme is divided into several sub programmes:

Snow and permafrost monitoring includes measurements for modelling of snow cover and vegetation (the seasonal and spatial variations in extent, snow depth, snow density, NDVI, etc.), micrometeorological measurements (energy balance, inversions etc.), active layer depth, etc.

Carbon flux monitoring includes measurements of CO2-flux and CH4-flux between the tundra and the atmosphere using eddy-correlation techniques and automated chambers in different habitats (dry heath and wet fen).

Soil water moisture and chemistry monitoring includes sampling of soil water from characteristic vegetation types to monitor transport and availability of nutrients for the vegetation in the active layer.
