The phytoplankton community in Massachusetts Bay has displayed significant inter-annual variability and possible trends over the last two decades, with increasing frequency and magnitude of strong Phaeocystis pouchetii blooms and generally opposite fluctuations in diatom abundances. An analysis of historical data suggests that changes in winter nitrate and silicate concentrations (both their absolute...
Rivers that flow through urban watersheds represent major conduits for the transport of anthropogenically derived nutrients and chemical contaminants to the coastal ocean. The fate of these materials is controlled not only by the physical dynamics of the riverine plume as it moves over the coastal shelf, but also by associated biological and chemical processes. The resulting interactions are complex...
