Tiivistelmä
During the summer 1992 three inner bays in the central archipelago of Åland, Northern Baltic Sea, were investigated. The three bays were all quite isolated with large draining areas. The investigated parameters were hydrographical: Secchi depth, salinity, temperature and oxygen; chemical: total nitrogen, nitrate, nitrite, ammonia, total phosphorus and phosphate.and finaly chlorofyll-a.
The inner parts of all three bays were in bad condition with high concentrations of nutrients. and high concentrations of chlorofyll-a. In the outer parts of the bays the water got better but still there was no sample station that could be classified as water in natural condition.
