Abstract:

The European Diatom Database (EDDI) is a web-based information system designed to enhance the application of diatom analysis to problems of surface water acidification, eutrophication and climate change. The Finish Lapland training set comprises 151 samples from lakes in the pH range 5.0-8.3. A sub-set of 30 of these lakes has been published as a training set (Weckstr?m et al. 1997). These lakes are distributed across the treeline, spanning boreal forest to tundra along a steep climatic gradient. The extended training set was produced with the intention of creating a transfer function for temperature. Surface sediment samples (0-1cm) were collected using a gravity corer during summer 1994 and 1995. Samples for analysis of water chemistry were collected during July 1995. Approximately 500 diatom valves per sample were counted. Only those species present at greater than 1% in any single sample and with >3 occurrences and that are identified to species level or better were included in the model (118 taxa).
