Earth Systems Science, or tellurology, considers the planet Earth as a system of connected and interactive phenomena governed by complex processes in the biosphere and the geosphere. Physical, chemical and biological transports and transformation processes along with interactions between the system compartments are being studied. Click here for model.
In Tellus’ research integrated field observations and modelling of the state of Earth systems together with experimental and theoretical studies of the relevant physical, chemical and biological processes are crucial. In particular, development and use of system models are corner stones in the work of Tellus.
The main research emphasis is on the sub-systems that constitute the climate system and the marine and terrestrial environmental systems. The most prominent fields of research in Tellus presently concern the Baltic environmental system and the Arctic/Sub-Arctic climate system. The former is strongly impacted by local anthropogenic activity while the latter is more impacted by global climate change.
Using models verified by experimental data, Tellus will analyse how the Baltic environmental system will be affected by changed anthropogenic activities and climate change. Of particular concern is developing a better understanding of the roles played by nitrogen and phosphorus in the eutrophication.
The coupling between Arctic land, shelf areas and deep basins as well as the interaction with the atmosphere is investigated through intensive field studies. The overarching challenge is to find out how the physical and the biochemical systems could be impacted by climate change, and as a consequence how the resulting changes in these systems feed back into the climate system.
