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).


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.

These grain-size and organic content analysis data may be used in numerical models of coastal dynamics and to better understand how the channels and ponds formed during Hurricane Dorian fill in.)

Altum-PT Digital Surface Models (U.S. Geological (USGS) researchers use the digital surface models (DSMs) to assess future coastal vulnerability, nesting habitats for wildlife, and provide data for hurricane impact models. The products span three sites on North Core Banks that can be compared to previous aerial survey products.)
