Chesapeake Bay National Estuarine Research Reserve

The Chesapeake Bay National Estuarine Research Reserve in Virginia (CBNERR) is a multi-component reserve located along the salinity gradient of the York River estuary.  Reserve components include Sweet Hall Marsh, Taskinas Creek, Catlett Islands and Goodwin Islands.  CBNERR is managed on a daily basis by the Virginia Institute of Marine Science, College of William and Mary.

Reserve Science
A recent publication in the American Geophysical Union publication Geophysical Research Letters describes a model of marsh migration into adjacent uplands and couples it with existing models of seaward edge erosion and vertical soil accretion to explore how ecosystem connectivity influences marsh size and response to sea level rise. The authors found that marsh loss is nearly inevitable where topographic and anthropogenic barriers limit migration. Where unconstrained by barriers, however, rates of marsh migration are much more sensitive to accelerated sea level rise than rates of edge erosion. This behavior suggests a counterintuitive, natural tendency for marsh expansion with sea level rise and emphasizes the disparity between coastal marsh response to climate change with and without human intervention.
