Shimon C. Anisfeld, Troy D. Hill, Donald R. Cahoon
2016, Estuarine, Coastal and Shelf Science (170) 145-154
Accelerated sea-level rise (SLR) poses the threat of salt marsh submergence, especially in marshes that are relatively low-lying. At the same time, restoration efforts are producing new low-lying marshes, many of which are thriving and avoiding submergence. To understand the causes of these different fates, we studied two Long Island...
