Project description
Increasing atmospheric CO2 concentrations cause an overall increase of CO2 concentrations in surface seawater and, consequently, a pH decrease. This mechanism, called Ocean Acidification (OA), has been recognized by both the scientific community and policy makers as one of the greatest threats to marine ecosystems but also to the well-being of society, through impacts on fisheries, aquaculture and tourism. The mechanism of OA is already fairly well understood and traceable in the open ocean waters, where large-scale projects and actions supply an enormous amount of observations and experimental data and where the magnitude of OA is to a large extent thermodynamically consistent with the increase in atmospheric pCO2. On the other hand, in the coastal and shelf seas, OA is still considerably understudied despite their high socio-economic importance and potentially great vulnerability to acidification due to often lower salinity and corresponding lower buffer capacity of waters as compared to open ocean. The Baltic Sea through its specific topography and the hydrological setting is one of the largest brackish water bodies on Earth. The brackishness of the basin creates a unique ecological structure but is also a root cause for a generally low buffer capacity of waters (expressed as total alkalinity, AT) to mitigate OA. The mean surface salinity of about 7 in the central Baltic Sea clearly shows the predominant role of the freshwater component in shaping the chemical composition and properties of the Baltic surface water. However, the knowledge about the role of freshwater input in shaping the AT fields and thus also pCO2 and pH variability in the Baltic Sea remains still insufficient. This is especially the case for the highly understudied southern and south-eastern parts of the Baltic and the large continental rivers flowing there, which drain limestone-rich catchment vulnerable to CO2-induced weathering. In consequence, this knowledge gap still hampers closing the AT mass balance for the entire Baltic and proper setting up biogeochemical models, which are the only tools to study the large-scale variability of pH and pCO2 changes and to forecast the development of OA in the future high-CO2 world. The main hypothesis in the project assumes that total alkalinity loads from continental rivers are increasing which substantially influences the alkalinity budget and pH and pCO2 variability in the Baltic Sea.
