European Diatom Database - UK Meres TP Dataset

This dataset includes 33 lakes from the Cheshire and Shropshire meres region of the English Midlands. They are all relatively small, shallow, lowland waterbodies.

All lakes are alkaline and nutrient-rich with base-rich geology. Surface sediment samples were collected during February 1993 by University College London and diatoms were counted by Helen Bennion. These sites form part of a larger diatom-total phosphorus training set of 152 NW European lakes (Bennion et al., 1996) and have also been used to develop a chironomid-total phosphorus inference model (Brooks et al., 2001).
