“...Rising sea level poses a long-term threat to salt marshes worldwide (Crosby et al., 2016). Marshes respond to increased inundation through enhanced accretion and inland migration (Feagin et al., 2010; Kirwan et al., 2016; Morris et al., 2002; Torio and Chmura, 2013). Vertical accretion allows the marsh to maintain its elevation relative to mean sea level and inland migration, through the conversion of the adjacent uplands to marsh, helps compensate for areal losses caused by edge erosion and rising sea level. However, a marsh’s ability to vertically accrete depends on sediment availability, and the ability to migrate onto uplands depends on topography....”
