Other ID: Marconi Beach 2021

Status: Pending

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s): Coastal Model Applications and Field Measurements (LQ00DYN)

Principal Investigator(s): Christopher Sherwood

Affiliate Investigator(s): Peter Traykovski (WHOI)

Information Specialist(s): Jin-Si Over

Data Type(s): Imagery: Other Imagery, Sonar: Single Beam, Sampling: Geology, Location-Elevation: Navigation, Imagery: Photo

Scientific Purpose/Goals: To characterize the beach and nearshore morphology and evaluate the USGS Total Water Level and Coastal Change Forecast. Use of 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. This includes the installation, reference mark occupation, and collection of external camera calibration data for ARGUS cameras (target coordinates) at Marconi Beach; subaerial survey measurements to map beach; aerial imagery from kite/balloon to map beach; bathymetric soundings from WHOI autonomous surface vehicle to map nearshore; and collect sediment samples.


Start Port/Location: Falmouth, MA

End Port/Location: Falmouth, MA

Start Date: 2021-01-14

End Date: 2021-04-20

Equipment Used: Ricoh GR II, Spectra Precision SP80, PPK GPS, Sampling scoop, Echosounder ECS 24D, Aeropoint targets

Information to be Derived: Location and orientation of the new Marconi ARGUS camera system; topography and bathymetry of the beach and nearshore region in view of the cameras and grain size distribution.

Summary of Activity and Data Gathered: 2021-03-10: Survey at Marconi Beach (J. Over, J. Cramer, C. Sherwood, E. Marsjanik, P. Traykovski) ASV launched with single beam echo-sounder to measure bathymetry, Two SP80 recievers used, one connected to base, one using CORS network through hotspot. Moved plywood targets in front of camera and also took 20 sediment samples. 2021-03-17: Survey at Marconi Beach with helium kite and one rover connected to CORs via hotspot. Aeropoints and plywood targets deployed for ground control and CACO2 camera calibration. (J. Over, E. Marsjanik, R. Bales, and P. Traykovski).
