Other ID: Cape Lookout National Seashore - North Core Banks Field Work

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s): Other (Other)

Principal Investigator(s): Sara Zeigler, Christopher Sherwood

Affiliate Investigator(s):

Information Specialist(s): Jin-Si Over

Data Type(s): Imagery: Video, Sonar: Single Beam, Visual Identification: Ground Truthing, Location-Elevation: Navigation, Sampling: Geology, Imagery: Photo

Scientific Purpose/Goals: To collect ground truth data on North Core Banks that validate landcover types, erosion and accretion in newly formed ponds from Hurricane Dorian (2019) and subsequent recovery. Install semi-permanent ground control points (large 3x3 ft painted black and white targets).

Vehicle(s):

Start Port/Location: Morehead City, NC

End Port/Location: Portsmouth Island, Long Point Cabins

Start Date: 2022-10-16

End Date: 2022-10-21

Equipment Used: Grab sampler, Sampling scoop, DJI Matrice, Spectra Precision SP80, Reconnaissance, Kogger SONAR 2D, Altum-PT, Parrot Anafi, Ricoh GR II

Information to be Derived: Grain size, bathymetry, topography, vegetation identification.

Summary of Activity and Data Gathered: Set up and occupied with the base five semi-permanent ground control targets, got sand samples transects across 3 study sites, used kayaks to grab a few sediment samples from the ponds, performed drone (M600 and Anafi) and bathymetry (YellowCat) surveys on three ponds, and characterized conditions and vegetation at more than a hundred sites with RTK, phone camera, and visual identification. We added several RTK ground point transects at the ends of the North Core Banks.
