Abstract
    Since the closure of the Grevelingen estuary in 1971 a large phosphate (P) increase in the new formed Lake Grevelingen has set in. Mass budgets show that a major part of this P increase must be attributed to P mobilization from the sediment. P sediment-water interaction shows a consistent seasonal pattern, P mobilization taking place from May to August (viz. 12,5 mg P.m-2.day-1) and P accumulation during the rest of the year (viz. 5,5 mg P.m-2.day-1). In a molecular diffusion model interstitial water orthophosphate content cannot account for this observed exchange pattern.
