| Abstract |
Patterns of changes in phytoplankton colour and phytoplankton species counts, sampled by the Continuous Plankton Recorder (CPR) in the past sixteen years, appear to be widespread in the North Sea. Unexplained anomalies between phytoplankton colour and the species counts might possibly be caused by an increase in microflagellates. The extensive nature of these changes implies that they are unlikely to be related to pollution but are probably related to major climatic events that have taken place over the same period. A programme to examine changes in community structure and to extend the record back to 1931 by utilizing prewar CPR data is currently under way. |
