Abstract On the basis of theoretical considerations and a small body of available empirical evidence, the rate of dissipation of turbulent mixing energy appears to influence the behavior and physiology of plankton in marine and freshwater ecosystems. In the relatively large microcosms at the Marine Ecosystems Research Laboratory at the University of Rhode Island, a mechanical mixing device was included in an attempt to provide a turbulence regime that is appropriate for plankton from Narragansett Bay, a shallow (9-m), well-mixed estuary. The characteristics of water mixing and turbulent energy dissipation in the microcosms are described and compared with the bay by use of a number of measures. The rate of vertical water mixing appears to be considerably more rapid in the tanks than in Narragansett Bay, but the horizontal turbulent field appears to be less than that generally found in near-shore marine waters.
