Project description
Climate change and eutrophication deteriorate the health of the Baltic Sea. Despite being tightly linked, with disturbances in the O2 status forming the nexus, the feedbacks between the problems have remained largely unexplored. The research on greenhouse gases has mainly focused on concentrations and sea-air interface fluxes, with hardly any data gathered on the actual microbial processes that in the end construct the said fluxes, or on the factors controlling the production/consumption balance. We will evaluate the Baltic Sea sources and sinks of two essential greenhouse gases, N2O and CH4, with focus on the factors controlling the balance between production and consumption of the gases, linked to the mineralisation processes, in which the said gases are formed. Mineralisation, in turn, affects and is affected by eutrophication and climate change. The data is used to upgrade ecosystem models, making them powerful tools in creating scenarios for the development of the Baltic Sea.
