Barrier-island Migration Drives Large-scale Marsh Loss
If you’ve visited North Carolina’s Outer Banks or other barrier islands, you’ve likely experienced their split personalities — places where high waves can pound the sandy ocean shore while herons stalk placid saltmarsh waters just a short distance landward. New research by a team from William & Mary and its Virginia Institute of Marine Science shows that these seemingly disparate ecosystems are in fact closely coupled, and that rapid landward migration of barrier-island sands is leading to large-scale loss of adjacent saltmarshes.
Sea Level Rise Will Disproportionately Hit U.S. This Century, NOAA Warns
Global sea level rise is unfolding at a stunning pace, and a new report from the National Oceanic and Atmospheric Association (NOAA) says the U.S. will find itself directly in the crosshairs. Over the coming decades, some parts of the nation’s coastline will be hit harder than others, the study finds. The report — co-authored with the U.S. Department of Commerce, the U.S. Geological Survey, the Environmental Protection Agency, the South Florida Water Management District, and scientists from Rutgers and Columbia University — outlined six likely scenarios for sea level rise, ranging in severity from low to extreme, so that communities and the federal government can plan around those likelihoods.
