Marshes are ubiquitous landforms in estuaries and lagoons, where important hydrological, morphological and ecological processes
take place. These areas attenuate sea action on the coast and act as s...
A spatio-temporal assessment of back-barrier salt marsh change: a comparison of multidate aerial photography and spatial landscape indices
barrier island salt marsh aerial photography
2015/8/21
A study of back-barrier salt marshes was conducted to investigate whether or not urbanization has impacted the distribution and
fragmentation characteristics of the marshes. Topsail Island and Masonb...
Salt Marsh Primary Production and Its Responses to Relative Sea Level and Nutrients in Estuaries at Plum Island, Massachusetts, and North Inlet, SouthCarolina, USA

2015/7/16
Feedbacks between flooding and plant growth that help to stabilize marshes against rising sea level are being investigated in estuaries at Plum Island, Massachusetts, and North Inlet, South Carolina. ...
Below the Salt Marsh Surface: Visualization of Plant Roots by Computer-Aided Tomography
Computer-Aided Tomography Salt Marsh Surface
2015/7/16
As sea level rises, salt marshes become subtidal mudflats unless soil surface accretion occurs at rates fast enough to keep the marsh from being submerged (Brinson et al., 1995). The individual proces...
