Abstract: Salt marsh ecosystems are maintained by the dominant macrophytes that regulate the elevation of their habitat within a narrow portion of the intertidal zone by accumulating organic matter and trapping inorganic sediment. The long‐term stability of these ecosystems is explained by interactions among sea level, land elevation, primary production, and sediment accretion that regulate the elevation of the sediment surface toward an equilibrium with mean sea level. We show here in a salt marsh that this equilibrium… Show more

“…Marsh vegetation influences accretionary processes by contributing autochthonous carbon to the soil and enhancing sediment trapping of allochthonous particulate carbon mineral sediment and deposition with their stems (Morris et al 2002;Baustian et al 2012). Accretion is commonly measured via marker horizons, such as feldspar, and particle-reactive radiotracers, such as 7 Be, 137 Cs, and 210 Pb (Callaway et al 1996;Taylor et al 2013).…”

“…Sequences of salt-marsh sediment are a valuable archive for reconstructing RSL because salt marshes accrete sediment to preserve their elevation in the tidal frame under regimes of rising RSL where sediment supply is not limited, or where salt-marsh accretion results primarily results from organogenic growth (Morris et al, 2002). However, samples of salt-marsh sediment used to reconstruct sea level may have undergone post-depositional lowering (PDL) by compaction of underlying sediment (Jelgersma, 1961;Bloom, 1964;Allen, 1999Allen, , 2000van Asselen et al, 2009).…”

“…Much attention has been devoted to the understanding and description of the processes which lead to observed equilibria in the vertical direction, or lack thereof, producing a rather comprehensive understanding of the controlling biological and physical processes [Allen, 1990;Morris et al, 2002;D'Alpaos et al, 2007;Kirwan and Murray, 2007;Marani et al, 2007;Mudd et al, 2009;Marani et al, 2010]. On the contrary, "lateral" evolution mechanisms have received comparatively much less attention, even though marsh degradation associated with edge erosion is arguably the chief mechanism by which marshes in coastal areas worldwide are being lost [Schwimmer, 2001;Gedan et al, 2009;van de Koppel et al, 2005;Mariotti and Fagherazzi, 2010].…”
