A 6‐h endogenous periodicity in chlorophyll synthesis, phased to tidally induced changes in the stability of the water column, was evidenced in a large volume sample of a natural estuarine phytoplankton population. Chlorophyll concentrations nearly doubled over a period of 2–3 h. This field evidence is in conceptual agreement with a physiological model of light‐shade adaptation based on changes in the rates of chlorophyll synthesis.
