| Abstract |
Synoptic surveys of the plankton at a depth of 10 m in the North Sea have been carried out at monthly intervals using Continous Plankton Recorders. Fluctuations in abundance of all diatoms and some dinoflagellates from one year to another have shown a downward trend from 1958 onwards and all taxa, except Thalassiosira ssp. were much below average in 1980. In general, the values of the first principal component of variability from one year to another of the phytoplankton biomass, the occurrence of rare species of phytoplankton the westerly weather index and wind strength are correlated. Their effects may have been additive and responsible for the low abundance in that year. |
