View new CMGDS report form

Other ID: Head of the Meadow 2023

Status: Completed

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

Funding Program(s): Next-Generation Total Water Level and Coastal Change Forecast (WH) (MN00U03)

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 used to validate the USGS Total Water Level and Coastal Change Forecast and 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 the beach; aerial imagery from kite/balloon (Heli-kite) to map beach; bathymetric soundings from WHOI autonomous surface vehicle to map nearshore. Surveys are repeat from 2020-015-FA, 2021-014-FA, and 2022-015-FA at Head of the Meadow.

Vehicle(s):

Start Port/Location: Falmouth, MA

End Port/Location: Falmouth, MA

Start Date: 2023-03-10

End Date: 2023-04-07

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

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: Helikite was deployed on March 10 - C. Sherwood, J. Over, P. Traykovski, and I. Reeves assisted. Photos were overexposed on first two attempts and thus the tide came up so survey does not cover as much of the low beach as previous field activities. Bathymetry was done on April 7 by C. Sherwood, P. Traykovski, and J. Over - Yellowfin was used and extent mapped is greater than previous surveys due to interesting features observed from the beach.
