Coastal Marsh Health Index

Data Access

The Coastal Marsh Project generated a Coastal Marsh Health Index product in 1997 by analyzing the surface condition of coastal marshes and detecting areas at risk for rapid loss of land area. Overall coastal marsh health and potential for deterioration was assessed for much of the east coast of the United States. The result of Project operations was the development of this data set and improved scientific analysis of coastal marshes.
