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, 2022-015-FA, 2022-011-FA at Head of the Meadow. Sister camera to Marconi Beach
Location
Head of the Meadow Beach, Truro Cape Cod National Seashore, Barnstable County, MA, United States
Summary
Single-beam data was collected on February 9th (P. TRaykovski, J. Over, and L. Vanderveen). We were hailed on and it was very cold. The boat got caught up in seaweed multiple times in the nearshore and the rudder snapped on the last one. Data was still collected, though more patchy than the last few times. The Helikite was launched on March 20th (P. Traykovski, J. Over, L. Vanderveen, and M. Anderberg) with 10 Aeropoints. Wind was 10-15 mph, gusting 20-25. The helikite got a puncture early on that was patched. SONY camera was attached and it fell off on the first transect - camera was still functioning but damaged and we finished the survey with an oblique angle. Due to wind conditions, the base of the bluff was poorly photographed.
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
Survey days and personnel will be based on availability and weather. Mira Anderberg also on staffing (intern)
