European Diatom Database-Danish TP Dataset

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.

This dataset includes 28 relatively small, shallow lakes from Denmark. All sites are lowland, alkaline and nutrient-rich. Surface sediment samples were collected during 1991 and diatoms were counted by John Anderson. The Danish data set is not published but is based on the Water Environment Survey lakes (Kristensen et al., 1991). These sites form part of a larger training set used to develop a NW European diatom-total phosphorus inference model (Bennion et al., 1996). Palaeolimnological studies have been undertaken at a number of these sites (Anderson & Odgaard, 1994; Bennion et al., 1996a).
