Primary production, dinoflagellates, biomass
Despite higher concentrations of nutrients and chlorophyll a, available data indicate that, over an annual cycle, primary production in the Mid-Atlantic Bight is little if any higher than that in shelf waters south of Cape Hatteras. Principal factors regulating productivity in the northern region appear to be the long period of low temperatures and reduced insolation and deep mixing during the winter and dominance of slow growing dinoflagellates during the late summer. Periods of very high production occur during the spring and fall. In contrast, the productivity to the south seems to show little seasonal fluctuation. Warm temperatures and adequate light maintain high growth rates year-round and although the biomass is low, the rapid turnover of cells results in a relatively high total productivity.
