| Purpose | 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. | ||||||||
| Location | Marconi Beach, Wellfleet, 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 | Yearly update on topography and bathymetry of the beach and nearshore region in view of the cameras. | ||||||||
| Comments | 2022-03-12: Used helikite, SP80, and aeropoints to collect topography data and imagery (J. Over, M. Bartlett, C. Sherwood, P. Traykovski) 2022-03-16: Bathymetry with Yellowfin and single-beam echosounder (J. Over, C. Sherwood, and P. Traykovski) Entries for this field activity are based on entries from Field Activity 2021-014-FA for the Head of the Meadow Field Work and from Field Activity 2021-022-FA. | ||||||||
