European Diatom Database

It has has been developed by combining and harmonizing data from a series of smaller datasets from across Europe and parts of Africa and Asia. At present EDDI contains diatom counts and associated environmental information for over 2000 taxa in 1350 modern samples from 23 regional training datasets.

All details of the training sets, diatom samples and taxa can be listed or explored graphically via web pages and software linked to the EDDI database. Taxonomic conventions used in merging the EDDI datasets are fully documented with over 2000 digital images, and environmental reconstructions using EDDI transfer functions are available on-line or via free downloadable software. The datasets include the ALPE mountain lake dataset, Italian mountain lake dataset, Spanish mountain lake dataset, UCL mountain lake dataset, Norwegian dataset, Finnish dataset, Kola penninsula pH dataset, Combined pH dataset, Svalbard pH dataset, SWAP dataset, Swedish dataset, African dataset, East African dataset, North African dataset, Caspian saline lake dataset, Combined salinity dataset, Spanish saline lake dataset, Welsh TP dataset, Central European dataset, Danish TP dataset, French Massif Central TP dataset, Northern Irish dataset, NW Europe dataset, UK meres TP dataset, Southern England dataset, Swiss dataset, and Combined TP dataset.
