Sediment is the principal mechanism for the deposition of phosphorus (85%) and 70 % of the nitrogen delivered to surface water bodies (Karr and Schlosser, 1977) and the principal source of phosphorus enrichment of surface waters (Boto and Patrick, 1979; Nowak, 1988).

Eutrophication Wikipedia

Eutrophication is a common phenomenon in coastal waters. In contrast to freshwater systems, nitrogen is more commonly the key limiting nutrient of marine waters; thus, nitrogen levels have greater importance to understanding eutrophication problems in salt water.
