Water quality status
Salinity, water temperature and water quality in terms of nutrients, chlorophyll a concentration and secchi depth is monitored at 8 stations in the bay, outside coastal, and open Baltic Sea Proper. Stations are sampled once a month in winter, every week in spring, and every second week during the rest of the year. Additionally, nutrient concentrations are monitored in 3 streams entering the bay as well as in the freshwater discharged from Lake Mälaren at Södertälje.
