Understanding Sediment Availability to Reduce Tidal Marsh Vulnerability to Sea Level Rise in the Northeast

Tidal marshes along the Atlantic coastline provide critical habitat for a wide variety of wildlife, help protect coastal ecosystems by filtering excess nutrients and pollutants, and serve as a buffer against coastal erosion and flooding. However, these important habitats and the species that rely on them are threatened by rising sea levels. Resource managers from the National Park Service Northeast Region, U.S. Fish and Wildlife Service Northeast Region, and the state of Massachusetts have expressed a need for a scientific analysis of the vulnerability of these salt marshes to sea level rise. The supply of sediment to marshes is a critical factor controlling marsh survival and adaptability to rising sea levels. Determining where [...]
