High resolution reconstruction of ancient flooding and climatic histories during these 2000 years by the annually laminated lake deposits in Finland, presumed by micro-fossil assemblages (Diatoms and Chrysophyceae Cists)

Abstract

In Finland, there are plenty freshwater lakes where seasonal lake environmental changes were recorded as annually laminated deposits. We surveys diatom fossil assemblages at the following three lakes in the central Finland to reconstruct high resolution environmental histories using annually laminate time setting of the deposits.

Our target was about these 2000 years to presume anthropogenic impacts and global climatic impacts during the Roman Warm Period, the Great Migration Period, the Medieval Warm Period, the Little Ice Age and the Global Warming.
