Abstract

The volume of limnological research in Finland has considerably expanded during recent decades, especially in the 1970s, with elevated funding and improved study facilities. Projects have become larger, the publication has intensified and has been increasingly directed to refereed international journals. The number of aquatic scientists has increased, new university centres have been established and old ones developed. Government research institutes dealing with aquatic resources have been founded and developed. Applied limnology developed rapidly during the 1960s, with a heavy bias towards physical and chemical limnology, as reflected in the extensive water quality monitoring programs started by the water authorities during that decade. Basic hydrobiological research was revived in the early 1970s with the first truly integrated lake ecosystem study in Finland on the energy flows in Lake Pääjärvi; several other ecosystem studies were completed later. The early work in the 1970s was largely descriptive, but later projects in the 1980s (e.g. studies on the food chains in small humic lakes and on the effect of nutrients on the pelagic carbon cycle in the Baltic Sea) have adopted a more experimental approach. Other important study fields devoloped during the 1970s and 1980s were paleolimnology and ecosystem modelling. Research on the effects of airborne acidification started in the 1980s. The artificial gap between applied and basic limnology is narrowing: water managers are starting to realize the importance of ecological interactions.
