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 the installation, reference mark occupation, and collection of external camera calibration data for ARGUS cameras (target coordinates) at Marconi Beach; subaerial survey measurements to map beach; aerial imagery from kite/balloon to map beach; bathymetric soundings from WHOI autonomous surface vehicle to map nearshore; and collect sediment samples.
Location
Marconi Beach, Wellfleet, Cape Cod National Seashore, Barnstable County, MA, United States
Summary
2021-03-10: Survey at Marconi Beach (J. Over, J. Cramer, C. Sherwood, E. Marsjanik, P. Traykovski) ASV launched with single beam echo-sounder to measure bathymetry, Two SP80 recievers used, one connected to base, one using CORS network through hotspot. Moved plywood targets in front of camera and also took 20 sediment samples.
2021-03-17: Survey at Marconi Beach with helium kite and one rover connected to CORs via hotspot. Aeropoints and plywood targets deployed for ground control and CACO2 camera calibration. (J. Over, E. Marsjanik, R. Bales, and P. Traykovski).
Info derived
Location and orientation of the new Marconi ARGUS camera system; topography and bathymetry of the beach and nearshore region in view of the cameras and grain size distribution.

Marconi beach Helium balloon imagery survey and more targets for camera calibration set-out. (J. Over, E. Marsjanik, R. Bales, and P. Traykovski).
These RGB 3-band images were collected of the waterline, beach, and bluffs with sufficient overlap to produce structure-from-motion photogrammetry products to create a model of Marconi Beach
An Emlid Reach M2 was attached/hot shoed to the Richo GR II to take a GPS position every time a picture was taken. A base station was also simultaneously taking information. After the field activity the GPS log and base logs were processed.
Images collected with camera (Ricoh GRII) attached to a helium powered balloon-kite (Allsopp Helikite LTD) (JPG image format, EXIF headers have been added to include navigation and time tags).
