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 Spanish training set includes 74 samples from 57 sites situated between 42N and 36S in latitude, 6W and 2E in longitude. Sampling was restricted to endorheic zones of flat topography, from the interior plateau: La Mancha and Albacete (central Spain) and Zamora (northeastern Spain), and from the lowlands of Andaluc?a (southern Spain) and the Ebro basin (northeastern Spain), at altitudes ranging from 2-1020m asl. Conductivity ranges from 150 to 338,000 ?S cm-1. There is a tendency for water chemistry to be dominated by sulphates in the central plateau region, chlorides in Andaluca, and mixed chloride- or sulphate-dominance in the Ebro basin, dependent on the mineralogy of underlying Tertiary or Triassic marine or continental evaporites. Carbonate-dominated waters are rare, comprising a small number of freshwater, karstic systems. Samples were collected by J. Reed during her PhD (UCL Geography). Following removal of four outliers from the training set, a conductivity transfer function (r2 = 0.91) was derived for Spanish salt lakes (Reed 1995, 1998), which has been applied to one Spanish sequence (Reed 1995, Reed in press, Reed et al., 2001) and in unpublished work in Mexico. Based mainly on the above combined African transfer function, optima from the Spanish transfer function were also used in conductivity reconstruction for sites in Turkey (Reed et al. 1999, Roberts et al. 2001).
