Information Specialist(s): Steven Suttles, Olivia De Meo
Data Type(s): Time Series: Mooring (physical oceanography), Sampling: Geology, Environmental Data: Meteorology
Scientific Purpose/Goals: We propose to collect detailed hydrodynamic measurements in a cross-shore array spanning the nearshore and beach/dune, as well as topo-bathy maps, 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.

Summary of Activity and Data Gathered: The USGS collected detailed hydrodynamic measurements in a cross-shore array spanning the nearshore and beach/dune, as well as topo-bathy maps, throughout the storm and recovery period(s) during hurricane season. Observations from this site provided 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 provided 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. During the field campign spanning 9/1/21- 10/31/21. The USGS installed two Coast Cams in stereo that were used to create 3D images of the beach every hour and track changes in water level at the study site. The USGS Coastal and Estuarine Dynamics Group also deployed a Nanopod at Pea Island DUNEX experiment site to collect oceanographic information. The USGS also used an autonomous surf vehicle, built by Peter Traykovski of WHOI, to map the bathymetry of the Pea Island DUNEX Experiment Site.

Notes: Time series moorings will be deployed on jetted/driven pipe both in the surf zone and on the beach.
