Digital surface model representing Marconi Beach, Wellfleet on March 11, 2022

Metadata Updated: July 6, 2024

The data in this release map the beach and nearshore environment at Marconi Beach in Wellfleet, MA and provide updated environmental context for the 2021 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is related to the field activity 2022-014-FA and a collaboration with the National Park Service at Cape Cod National Seashore to monitor the region that falls within the field of view of CoastCam CACO-02, which are two video cameras aimed at the beach. In March 2022, U.S Geological Survey and Woods Hole Oceanographic Institute (WHOI) scientists conducted field surveys to map the CoastCam field of view. Elevation data were collected using a real time kinematic satellite navigation system (RTK-GNSS) receiver attached to a pole and walked on the beach. Images of the beach for use in structure from motion were taken with a camera (SONY a6000) and a post-processing kinematic (PPK) system attached to a helium filled balloon-kite (Helikite). High-precision targets (AeroPoints) and plastic tarps were used as ground control points to georeference the imagery. Bathymetry was collected in the nearshore using a single-beam echosounder mounted on a surf capable self-righting electric autonomous surface vehicle. Agisoft Metashape (v. 1.8.1) was used to create an orthomosaic and digital surface model, which was merged with the bathymetry in MatLab (v. 2020b) to create a continuous topobathy product.
