Observations of dissolved oxygen in the Test Estuary, Southern England have shown lowest levels following a mid summer phytoplankton bloom. The bloom was dominated by the ciliate Mesodinium rubrum (Lohmann). A numerical model has been developed to calculate the water circulation, vertical mixing, dissolved oxygen and chlorophyll a. To obtain good agreement between observed and predicted dissolved oxygen and chlorophyll a distributions, it was necessary to simulate a unique characteristic, the diurnal vertical migration of Mesodinium.
