In the Biogeochemistry Unit we study the natural processes and their interaction with human activities that drive the major biogeochemical cycles and ultimately govern the composition of the environment. From the Arctic to the tropics, we combine large-scale field studies with molecular and isotopic methods to track changes, quantify transport and trace sources of substances such as carbon, nutrients, metals and organic compounds and contaminants in water, air and soil. We aim at incorporating our observations and scientific understanding into mathematical models for assessing and predicting key processes of the atmosphere-biogeosphere, with particular focus on aspects related to climate change. We also support environmental agencies in assessing the status and large scale changes of the environment.
