We propose to deploy a bottom landing frame in the nearshore off of Pea Island NWR to collect detailed waves and current data in conjunction with hydrodynamic measurements in a cross-shore array spanning the nearshore and beach/dune, topo-bathy survey data, throughout the storm and recovery period(s) during hurricane season. Observations from this site will provide insight into cross-shore storm processes and impacts, including wave transformation and shoreline water levels, rapid changes in coastal elevations, on/offshore sediment exchanges, and resulting habitat changes. These detailed measurements will provide a more complete understanding of storm impacts and recovery on natural beach/dune systems, which will allow us to validate and improve forecasts of water levels, coastal change, and habitat.
Location
Pea Island National Wildlife Refuge, Hatteras Island, North Carolina, United States, Atlantic Ocean
Info derived
Waves, currents, pressure, water level, meteorology, sediment grain size.
Comments
R/V Shearwater for this work is out of the Duke Marine Lab in Beaufort, NC, not a NOAA vessel.
Grab sampler used is a new Shipek owned by WHCMSC.
