Abstract

The sediment accumulation rate within a small Spartina alterniflora marsh in Maine has been determined by measuring the amount of peat accretion on top of human-produced boards protruding from an exposed face of the marsh. Boards are at depths of 50-140 cm, suggesting sediment accumulation rates of 6.2-7.0 mm/year. Aggradation in small marshes such as Shipyard Cove should be able to keep pace marginally with the anticipated sea-level rise due to "greenhouse' warming, given sufficient sediment supply. -from Authors
