Coastal wetlands are increasingly affected by rising sea level, and Jamaica Bay marshes as well as Long Island Sound salt marshes are extremely vulnerable. Using multidisciplinary tools including pollen and spores, LOI, x-ray fluorescence and N and C isotopes, we present the last 400 years of change in these marshes, and demonstrate how they have shifted both function and value to local residents throughout history. We examine vegetational change, carbon sequestration, and heavy metal pollution, as well as their protective and enrichment roles throughout history.
