Abstract:

Chesapeake Bay marshes, in their wide variety of vegetation types, salinity ranges, and environmental settings provide a unique perspective on the relations between marsh vertical accretion rates and sea-level rise in a relatively small geographic area. Estuarine marshes, occurring along the meanders in the sediment trap portions of major Bay tributaries, appear at least to be keeping abreast of rising sea levels; in some marshes, vertical accretion rates may be exceeding local rates of sea-level rise.
