The Kola diatom-pH training set comprises 24 small oligotrophic lakes located along a vegetation gradient in the central and western parts of the Kola Peninsula, Russia. The surface sediment diatom flora from the KOLA lakes is typical for oligotrophic, diluted arctic and alpine lakes. The diatom assemblages from the KOLA lakes are close floristically to the assemblages from the ALPE lakes (Cameron et al., 1999) and to the assemblages from northern Sweden (Korsman and Birks, 1996). The diatom optima generated by the KOLA model are generally in agreement with the optima derived by other models (e.g. ALPE) although KOLA diatom optima are generally higher compared to the ALPE and SWAP.
