2019-9-25 · Salt marsh habitats support a diverse array of estuarine species but are vulnerable to increased inundation resulting from sea-level rise. In order to characterize relationships between vegetation and elevation and inform assessments of risk to salt marsh communities from projected sea-level rise, we collected vegetation and elevation data at 42 salt marsh sites in

Evaluation of a UHF Radar Surface Current Mapping

2007-12-1 · Topographically, salt marshes consist of an extensive cover of relatively featureless marsh platforms dissected by a network of highly sinuous sub- and intertidal channels. The flow is tidal and is accompanied by large, rhythmic fluctuations in water depth such that the marsh and intertidal creeks drain and fill with each tidal cycle.
