“…Thus, plants may not directly reduce erosion on cliff-like edges by binding the soil with their live roots, but may do so indirectly by modifying soil properties before cliff formation. Indeed, coastal plants can build coastal landforms through a coupled process of ecological succession and sedimentary accretion (13,22). We conclude that coastal vegetation is best suited to modify and control sedimentary dynamics in response to gradual phenomena like sea-level rise or tidal forces (23,24), but is less well-suited to resist punctuated disturbances (25,26) at the seaward margin of salt marshes, specifically breaking waves.…”

This study challenges the paradigm that salt marsh plants prevent lateral wave-induced erosion along wetland edges by binding soil with live roots and clarifies the role of vegetation in protecting the coast. In both laboratory flume studies and controlled field experiments, we show that common salt marsh plants do not significantly mitigate the total amount of erosion along a wetland edge. We found that the soil type is the primary variable that influences the lateral erosion rate and although plants do not directly reduce wetland edge erosion, they may do so indirectly via modification of soil parameters. We conclude that coastal vegetation is bestsuited to modify and control sedimentary dynamics in response to gradual phenomena like sea-level rise or tidal forces, but is less well-suited to resist punctuated disturbances at the seaward margin of salt marshes, specifically breaking waves.coast ͉ hurricane ͉ wave attenuation ͉ wetland

“…Age of samples is 500 to 700 yr less than samples of high marsh peat from same depths in Barnstable Marsh and using Barnstable marsh sea levels, these samples lay 0.5 to 2 m below est. MHW level at time they were deposited (Redfield and Rubin, 1962). These discrepancies may have arisen from initial development of marsh at intertidal levels or from subsequent compaction.…”

The present list represents a major portion of the samples measured since publication of the last date list in 1963. As in previous lists, dates are reported in terms of the 5568 yr half-life. Infinite dates are reported as beyond a limit equal to 2Q above background. Nearly all of the samples were measured in one of three quartz counters with backgrounds of 0.7 to 1.2 cpm per liter of effective counting volume at working pressures of about two atmospheres. The age errors quoted are based only on the standard deviations in counting rates of sample and standards.

“…Through this response, salt-marshes preserve their elevation in the 57 tidal frame and the salt-marsh surface tracks rising RSL (e.g. Bloom, 1964;Redfield and Rubin, 1962).…”
