Field Activity 2022-034-FA

Identifier 2022-034-FA
Alternate names Cape Lookout National Seashore - North Core Banks Field Work
Purpose 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).
Location Cape Lookout National Seashore, North Core Banks, Cateret County, North Carolina
Summary 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.
Info derived Grain size, bathymetry, topography, vegetation identification.
Comments Funding project name is Project name is "Hurricane Florence Changes at Cape Lookout".

2022034FA_NCB_SedimentSamples Grab sampler Sediment sample analysis data from ponds to the beach on North Core Banks, NC in October 2022. 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.

NCB Landscape and vegetation photos and ground truthing data Reconnaissance Landscape and vegetation data and photos can be used for landcover classifications and ground truthing of aerial imagery. Jin-Si R Over
NCB Bathymetry Data Kogger SONAR 2D Kogger Raw files can be read as an echogram with free Kogger App, data has also been parsed into a CSV for location and depth information. Jin-Si R Over
Altum-PT Digital Surface Models Altum-PT 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. Jin-Si R Over

NCB UAS Imagery DJI Matrice True color and multispectral aerial imagery collected from UAS operations at North Core Banks, NC in October 2022. DJI Matrice was equipped with the Altum-PT and Ricoh GRII. Image locations are provided in a CSV. Jin-Si R Over
NCB UAS Photogrammetry Ortho Products Spectra Precision SP80 True color and multispectral (3- and 5-band) ortho products are to be used for identification of vegetation and other groundcover classifications. The panchromatic band can be used to pan-sharpen the other ortho products. Orthos are created using the imagery and ground control points. For the Altum-PT and Ricoh GRII cameras. Jin-Si R Over
