Phytoplankton-zooplankton interactions : data analysis and modelling (with particular reference to Ocean Station P (50⁰N, 145⁰W) and controlled ecosystem experiments) Parslow, John Stanley

Abstract

The anomalous phytoplankton seasonal cycle in the Subarctic Pacific has been attributed to grazing control. In simple classical models of the phytoplankton-zooplankton interaction, grazing thresholds are found to be necessary to obtain this type of control. Weathership observations at O.S.P. are analysed to provide a basis for a more realistic model. Phytoplankton are present at O.S.P. in almost uniformly low concentrations (about 0.4 mg Chla.m⁻³), have low photosynthetic efficiency (
