European Diatom Database-Welsh TP Dataset
Listed in NASA Earthdata CMR
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.
Description
This dataset includes 11 lakes distributed throughout Wales including small, shallow and large, deep waterbodies. All lakes are circumneutral to alkaline and cover a long total phosphorus gradient.
Surface sediment samples were collected by University College London during 1993-1994 and diatoms were counted by Helen Bennion and Tim Allott. The dataset is part of a project which aimed to develop an integrated biological classification scheme for 30 Welsh lakes (Allott & Monteith, 1999). These sites form part of a larger diatom-total phosphorus training set of 152 NW European lakes (Bennion et al., 1996a).

Palaeolimnological studies have been undertaken at a number of these sites (e.g. Bennion, 1995, 1996; Bennion & Appleby, 1999; Bennion et al., 1996b, 1997a. 1997b, 1998).
