Air-sea gas exchange

To globally get a sustainable development we need to know more about our climate and how the climate is changing. The increased anthropogenic emissions of greenhouse gases (mainly carbon dioxide) have most likely lead to an increased greenhouse effect and a global warming. The details of global carbon cycle and specifically the exchange of CO2 between the atmosphere and the surface are presently not fully known. Several feedback reactions (negative and/or positive) of the global carbon system on the changing climate are discussed. There is an ongoing debate on the relative role of the terrestrial biosphere and the oceans in absorbing some of the emitted anthropogenic CO2. The total effects of oceans are thought of as major sinks of carbon dioxide. The relative importance of marginal sea on northern latitudes is larger than what can be expected concerning the relatively small area. The objective of this research project is to better describe and estimate the air-sea flux of CO2 between the ocean surface and the atmosphere globally as well as focusing the Baltic Sea region.
