Abstract
    Since 1971, when the Grevelingen estuary was turned into a shallow saline lake, meadows of eelgrass have extended rapidly. The role of eelgrass, Zostera marina L., in the uptake and release of nutrients was investigated for 1977 in relation to studies on the nutrient dynamics of Lake Grevelingen. The internal concentrations of carbon, nitrogen and phosphorus in the above-ground parts showed minima for nitrogen (2% of dry weight (DW)) and phosphorus (0.15% of DW) in summer. The total year's production of above-ground biomass was calculated as 8510 tons ash-free dry weight (AFDW) for the entire Lake Grevelingen; 93% of eelgrass biomass entered the detritus pool.
