Abstract

Small arctic and subarctic lakes are known to be sensitive to climatic variation. Changes in external conditions are continuously recorded in their sediments in the form of aquatic organisms. The abundance of such organisms can therefore be used to reconstruct past environmental conditions. We use data collected from the Finnish Lapland to reconstruct post ice age temperatures. Nonparametric
smoothing has not been used often in this context. We find smoothing a viable tool both in the actual reconstruction phase and in the subsequent time series smoothing, where the SiZer method is used.
