文摘

Long-term rates of marsh accretion and mass accumulation in a coastal plain and lagoon-type estuary were compared Accretion rates in marshes of both estuaries were correlated with rates of organic matter and mineral sediment accumulation Accretion and accumulation rates were significantly higher in marshes of the coastal plain estuary Accretion and mineral accumulation rates did not exhibit the established inverse relationship with marsh elevation, distance to sediment sources, or other hydrogeomorphic properties
