The Pyrenees diatom-water chemistry dataset comprises surface sediment diatom samples and water-chemistry data from 98(?) lakes. The chemical data are published in Catalan et al. (1993) and a 28 lake sub-set of these data were used in the ALPE training set (see above). The full diatom/water-chemistry training set, however, remains unpublished. Diatom counts were made by Joan Garcia.
