Abstract
Coupling between the seasonal phytoplankton growth cycle and resuspension mechanisms in low depth areas was studied. Tidal flood in an estuarine inlet with a large area of intertidal flats was investigated with respect to nutrients and suspended particulate matter, during two different periods of the year. A prespring bloom period in March and another during the productive summer term in August were picked. Results indicate that tidal resuspension mechanisms are important in mobilizing NH4 + from the sediment surface pool, and that this additional input of the limiting nutrient is rapidly consumed in the flooding water column, in benefit of microphytes resident in the nutrient-poor, incoming,coastal waters.
