Field Activity 2022-015-FA

Identifier 2022-015-FA
Alternate names Head of the Meadow 2022
Purpose 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 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 and 2021-014-FA at Head of the Meadow.
Location Head of the Meadow Beach, Truro Cape Cod National Seashore, Barnstable County, MA, United States
Summary 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.
Info 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.
Comments 2022-03-10 Head of the Meadow was surveyed with RTK equipment and helium balloon kite (J. Over, C. Sherwood, N. Randall, P. Traykovski). 2022-03-18 Bathymetry surveyed with Yellowfin and single-beam, very foggy (J. Over and P. Traykovski)
