Summary

These data map in high detail surficial cross-sections of North Core Banks, a barrier island in Cape Lookout National Seashore, NC, in October 2022. U.S. Geological Survey field efforts are part of an interagency agreement with the National Park Service to monitor the recovery of the island from Hurricanes Florence (2018) and Dorian (2019). Three sites of outwash, overwash, and pond formation were targeted for extensive vegetation ground-truthing, sediment samples, bathymetric mapping with a remote-controlled surface vehicle, and uncrewed aerial systems (UAS) flights to collect multispectral imagery. Five semi-permanent ground control points were also installed and surveyed to act as control for additional aerial imagery collects via [...]

Purpose

Photos of the beach surface were taken next to a quarter for scale. The images were uploaded to the Sandsnap database to estimate grain size with a deep learning neural network (https://sandsnap-erdcchl.hub.arcgis.com). These grain-size 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.
