Aspects of the developmental history and paleolimnology of lakes in Finland

The developmental history of Finnish lakes can be studied both morphologically and stratigraphically. Former water levels are indicated by raised beaches and outlet channels, and fluctuations in water level can be inferred from the lithostratigraphy of the sediments. The stratigraphic systems is also the starting point for studies concerned with the changing biodynamics of lake ecosystems. Consequently, sediment stratigraphy is the fundamental basis of paleolimnology.
