    "descript": "Surveys with Uncrewed Systems (UxS) were used to collect remote sensing data at Marconi Beach on Cape Cod National Seashore, Wellfleet, Massachusetts after the area experienced multiple erosion events after fall storms in 2024 and the loss of National Park Service beach access stairs. The USGS has a stationary camera system (CoastCam) and meteorological station north of the parking lot on the bluff to observe waves and total water levels. UxS were approved to map the coast in view of the CoastCam and where the Park Service stairs were destroyed to help evaluate the conditions of the site and monitor landscape change from storm impacts. The data products will also help validate the CoastCam imagery datasets. Between September 2024 and March 2025, USGS personnel surveyed five times and collected natural (RGB) color images, lidar data, GPS data, and bathymetric data to produce elevation maps and orthomosaics.",
