Abstract Twelve flow-through estuarine microcosms were exposed daily to four different levels of UV-B radiation. In addition to a natural level of visible solar radiation. The parameters studied over a four week period were phytoplankton community composition, plankton biomass (ash-free dry weight), chlorophyll a concentration and primary productivity (radiocarbon uptake). With increased exposure to UV-B radiation there was an obvious alteration of the community composition. Daily exposure to enhanced levels of UV-B radiation also depressed the biomass, the chlorophyll a concentration and the radiocarbon uptake of samples from the ecosystems.
