The potential for substantial recycling and ex- porting of nutrients to the estuary exists. The absorption, conversion, and recycling abilities of marsh plants offer real opportunities for improving water quality^ (Woodhill, 1977). d. Sediment Accumulation. Marshes perform a valuable role in trapping sediments, thereby reducing turbidity in bays, sounds, and estuaries. Turbidity reduction is highly beneficial in protecting shellfish beds from excessive siltation and increasing light penetra- tion which promotes phytoplankton production. Chapman (1938) esti- mates accretion rates in New England salt marshes to be to centimeter per year and Ranwell (1964) reported an average value of to centimeter per year for temperate European marshes. Higher rates probably occur in certain marshes growing in sediment-rich 23.
