European Diatom Database

The European Diatom Database (EDDI) is a database of diatom training
datsets and transfer functions. 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.

The EDDI system makes these data available on-line and allows
diatomists to apply the transfer functions to sediment cores.
