The impacts of extreme storms can be striking. Here, winter nor’easters eroded sediments from an artificial dune at Fire Island, New York and moved them onto the beach and shoreface. Such erosion created a steep vertical face, or scarp. Erosion and overwash are expected to increase on Fire Island with rising sea levels. 

The USGS conducted UAS flights to map the Nauset Marsh and Coast Guard Beach areas of Cape Cod National Seashore on Tuesday, March 1, 2016. These are the first authorized UAS flights in the northeast region of the national park system, and were performed under a research permit according to FAA and DOI regulations.

Surface sediments will be analyzed for various physical parameters that will be used as initial conditions in hydrodynamic and sediment transport models.

Relative seagrass biomass in West Falmouth Harbor, MA, under current and potential future nitrogen loading scenarios. Seagrass biomass increases in western (seaward) portions of the harbor while eastern (landward) areas see new colonization by seagrass.
