Description:

Surface sediment samples from 24 sites within eleven back-barrier lagoons of Rhode Island and Massachusetts (USA) contain abundant (200-6000 cysts cm-3) and diverse (up to 40 taxa) dinoflagellate cyst assemblages. The lowest cyst concentrations and diversity are observed in lagoons with low salinity (<10). The pattern of spatial distribution of dinoflagellate cysts in these shallow estuarine environments is described. We assessed the relationship between the available multi-year water quality data and the composition of the dinoflagellate cyst assemblages using canonical correspondence analysis. Temperature and salinity are found to be the primary abiotic factors influencing cyst distribution in the coastal lagoons.
