USGS Coastal and Marine Geology Program

Field Activity Details for field activity 2021-014-FA

Other ID: Head of the Meadow 2021

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 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 subaerial survey measurements to map beach; aerial imagery from kite/balloon to map beach; bathymetric soundings from WHOI autonomous surface vehicle to map nearshore. Surveys are repeat from 2020-015-FA at Head of the Meadow.

Vehicle(s):

Start Port/Location: Falmouth, MA

End Port/Location: Falmouth, MA

Start Date: 2021-02-04

End Date: 2021-02-11

Equipment Used: Echosounder ECS 24D, UAS- heli-kite, Aeropoint targets, PPK GPS, Spectra Precision SP80, Ricoh GR II

Information to be Derived: Updated year of change at Head of the Meadow of the topography and bathymetry of the beach and nearshore region in view of the cameras.

Summary of Activity and Data Gathered: 2021-02-04: Survey at Head of the Meadow Photos were taken from Heli kite, aeropoints deployed, SP80 rover and base set-up, camera maintenance (S Brosnahan, J. Cramer, J. Over, E. Marksjanik, C. Sherwood, P. Traykovski). 2021-02-11: Survey at Head of the Meadow. ASV with single Beam echo-sounder launched by C. Sherwood and P. Traykovski to map bathymetry.
