map of middle atlantic bight showing locations of water level stationsHurricane Sandy Impacts Did Not Contribute to Subsequent Storm Flooding

Flooding in coastal areas bordering Great South Bay, N.Y. and Barnegat Bay, N.J. caused by winter storms that occurred following Hurricane Sandy was not influenced by changes Sandy made to barrier islands or other bay features, according to a new U.S. Geological Survey study.

The study of Barnegat Bay and Great South Bay looked at data from November 2012 to October 2013, when winter storms brought water levels in these bays to among the 20 highest storm water levels reached from October 2007- October 2013.

The study, “Water-level response in back-barrier bays unchanged following Hurricane Sandy,” by Aretxabaleta, A.L., Butman, B., and Ganju, N.K., is in the Geophysical Research Letters journal and available online.

RISC-KITUSGS oceanographer advises "Risc-Kit", a European Coastal Risk and Resiliency project

From May 5–10, Nathaniel Plant, an oceanographer with the USGS, traveled to Cambridge, UK to serve on a board of experts of Risc-Kit. Risc-Kit is a European Union (EU) effort to evaluate risks and resilience measures associated with flooding, storm surge, and erosion. The project will demonstrate a consistent approach at 11 locations across Europe. Nathaniel's role with the board was to evaluate the project's structure, objectives, and implementation. The Risc-Kit project is similar to the USGS National Assessment of Coastal Change Hazards project, so valuable lessons are expected to be gained from the EU experience.

USGS Scientists Study Coastal Erosion at Fire Island, NY

The U.S. Geological Survey is conducting a sediment-transport experiment on the inner continental shelf offshore of Fire Island, New York, to study the coastal response to storms. In early February 2014, scientists from the USGS Woods Hole Coastal and Marine Science Center, along with scientists from the Woods Hole Oceanographic Institution and the University of South Carolina, deployed oceanographic instruments to measure surface waves, ocean currents, water levels, salinity, and temperature. Recovery of the instruments and analysis of the data will take place starting in early May. This effort is in part a response to assess the impacts and help determine the resiliency of coastal systems, such as Fire Island, to storm events such as Hurricane Sandy.

Example of scaling coastal dune elevation changes across storm-impact regimesNew research on scaling coastal dune elevations published in Geophysical Research Letters

On April 24th, USGS research oceanographers Joseph Long and Nathaniel Plant, along with past USGS intern Anouk de Bakker (Utrecht University, Netherlands), published an article,"Scaling coastal dune elevation changes across storm-impact regimes," in Geophysical Research Letters. Using data from multiple hurricanes that made landfall in diverse coastal locations along the U.S. Atlantic and Gulf of Mexico coastlines, the article compares the magnitude of storm-induced dune erosion to the characteristics of the individual storms. While storms that inundate coastal dunes (storm surge exceeding coastal dune crest elevation) are generally expected to result in the largest amount of coastal change, the data used in this study indicates that more dune erosion can occur during storms where surge levels remain below the dune crest and waves overwash the protective dunes for the duration of the storm. Quantifying and understanding the erosion that occurs in these different storm-impact regimes is essential to understanding if, how, and when coastal areas will become more vulnerable to future storms.

Image showing wave time-series at inshore locationsUSGS research on probabilistic wave prediction published in Coastal Engineering

On May 4th, USGS research oceanographers Joseph Long, Nathaniel Plant, P. Soupy Dalyander, and Dave Thompson published an article in Coastal Engineering titled "A probabilistic method for constructing wave time-series at inshore locations using model scenarios." The study presents a method developed by USGS scientists to forecast wave characteristics and prediction uncertainty using a database of model 'hindcasts'. With this method, continuous wave time series can be quickly derived at any spatial location for use in marine infrastructure design, to evaluate sites for potential wave energy extraction, or to force nearshore circulation and sediment transport models.
