View new CMGDS report form

Other ID: Marconi Beach 2022

Status: Completed

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: Photo, Location-Elevation: Navigation, Sonar: Single Beam

Scientific Purpose/Goals: 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. This 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.


Start Port/Location: Falmouth, MA

End Port/Location: Falmouth, MA

Start Date: 2022-03-11

End Date: 2022-03-30

Equipment Used: Cerulean Sonar S-500 Sounder, PPK GPS, Aeropoint targets, Digital camera, UAS- heli-kite, Spectra Precision SP80

Information to be Derived: Yearly update on topography and bathymetry of the beach and nearshore region in view of the cameras.

Summary of Activity and Data Gathered: Field Surveys took two days. Helikite survey was completed at low tide with a mix of Aeropoints and tarp targets as ground control. RTK GPS measurements and Propeller network were within 2 cm. PPK GPS data on camera was post processed. Bathymetry was collected a week after the helikite survey - ASV Yellowfin with a single beam echosounder was successful. No issues.
