Field Activity 2023-012-FA

Identifier 2023-012-FA
Alternate names Marconi Beach 2023
Purpose To characterize the beach and nearshore morphology to validate the USGS Total Water Level and Coastal Change Forecast that uses the ARGUS Camera systems (CoastCams) to visualize and map the beach and nearshore region to determine the types of bar morphologies, their persistence and temporal variability, and the relationship of these changes to wave and water-level conditions. Includes subaerial survey measurements to map the beach; aerial imagery from kite/balloon to map the beach; and bathymetric soundings from WHOI autonomous surface vehicle to map nearshore. May include measurments to calibrate the CoastCam.
Location Marconi Beach, Wellfleet, Cape Cod National Seashore, Barnstable County, MA, United States
Summary Bathymetry data was collected with the ASV Yellowfin on March 20 by J. Over and P. Traykovski, P. Berube assisted. Helikite was flown on March 22 by J. Over, C. Sherwood, and assisted by M. Carson. Wind was onshore and thus the water line was not mapped.
Info derived Yearly update on topography and bathymetry of the beach and nearshore region in view of the cameras.
Comments There will be two days of surveying based on weather. Entries for this field activity are based on entries from Field Activity 2022-014-FA.
