European Diatom Database - Northern Irish DatasetEntry ID: uk_nc_eddi_NI
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.
This dataset includes 54 relatively small, shallow lakes from Northern Ireland. All sites are lowland, alkaline and cover a wide range of phosphorus concentrations. Surface sediment samples were ... collected during April 1990 and May 1991 and diatoms were counted by John Anderson. A regional diatom-total phosphorus transfer function was developed from these data and details are given in Anderson et al. (1993) and Anderson & Rippey (1994). These sites also 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 (e.g. Anderson, 1989, 1997; Anderson & Rippey, 1994; Anderson et al., 1993; Rippey et al., 1997).
