Water transparency can be measured with optical instruments and estimated with satellite sensors, but such measurements have been widely available for only a few decades. Estimates of water transparency using a white disk called a Secchi disk have be

We analyzed phytoplankton biodiversity trends in a 52 year (1967–2018) monitoring time-series from the archipelago of Helsinki, Gulf of Finland, the Baltic Sea. The community ordination revealed strong ordering of samples along the time axis (gener

Salinity is a major environmental predictor of phytoplankton species richness and composition. We hypothesize that the variation in phytoplankton richness along coastal salinity gradients is reflected in essential ecosystem functions like resource us

Finnish fisheries are regulated first and foremost by the EU Common Fisheries Policy (CFP) and quotas determined by the EU. Certain fisheries have also been certified according to the international Marine Stewardship Council (MSC) standard. The aim o

The physical and chemical properties of water are vital for aquatic organisms. Should changes in these conditions occur, responses would follow both in the distributions of species and ecosystem functioning. Water salinity is particularly critical be

Coastal systems experience strong impacts of ongoing environmental change, affecting fish communities and subsequently fishery yields. In the Baltic Sea, the combined effects of climate-induced changes and eutrophication-related pressures constitute
