European Diatom Database-Surface Waters Acidification Programme
Entry ID: uk_nc_eddi_swap

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 Surface Waters Acidification Programme (SWAP) calibration training set
included initially 178 surface sediment diatom assemblages and the associated
environmental variables from 170 sites. ... View entire text

Quality Data-screening reduced the 170 lakes to 167 lakes, which using
weighted averaging give superior results in terms of lowest root mean
squared errors of prediction in cross-validation (Birks et al. 1990a;
Birks et al. 1990b).
