Abstract

We present a training set, the database involving physical-chemical water parameters together with the subfossil Cladocera and diatoms community composition in the surface sediments of 64 postglacial lakes in NE Poland sampled along a wide trophic gradient (from oligo- to highly eutrophic). The most important water parameters measured in water were chlorophyll-a, electrical conductivity (EC) and oxygen concentration. In addition, total phosphorus (TP) and Secchi depth (SD) were determined for the surface water layer. The data collected will be used to calculate a transfer-function for quantitative reconstruction of trophic state in fresh water temperate lakes.

Keywords: Lake training-set, water properties, summer vertical profiles, subfossil Cladocera, subfossil diatoms
