The increase of atmospheric CO₂ concentrations in the atmosphere, as a result of human activities eg burning of fossil fuels has created great concern about the stability of our climate. Increasing atmospheric CO₂ concentration will in all probability result in changes in temperature, precipitation and/or their seasonal amplitudes. This feedbacks will be most effective at higher latitudes and will affect especially coastal and shelf areas.

The Polar oceans are the first areas where climate change can be detected, primarily in extent and volume of the ice cover. Increased temperature is likely to increase the sea ice melt and river-runoff which will affect the biological pump of carbon. Read more

The Baltic Sea is an adjacent sea to the Atlantic Ocean, with limited exchange with the ocean but intense land-sea interaction. Changes in the Baltic Sea carbon system can serve to monitor small-scale changes in the marine and regional carbon cycle. Read more

Satellite and ship-based observations are used to evaluate algorithms for estimates of air-sea CO₂ flux. In the subarctic North Pacific Ocean we study the processes driving the air-sea CO₂ flux and the response to climatic forcing. Read more
