Other ID: none

Status: Completed

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

Funding Program(s): Coastal Model Applications and Field Measurements (LQ00DYN)

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, Location-Elevation: Transects, Sampling: Geology, Sonar: Single Beam

Scientific Purpose/Goals: Collect external camera calibration data for CACO01 cameras (target coordinates); subaerial survey measurements to map beach; aerial imagery from kite to map beach; bathymetric soundings from WHOI autonomous surface vehicle to map nearshore.


Start Port/Location: Truro, MA

End Port/Location: Truro, MA

Start Date: 2020-03-04

End Date: 2020-03-10

Equipment Used: Echosounder ECS 24D, PPK GPS, Spectra Precision SP80, Aeropoint targets, Plywood targets, Ricoh GR II, Sampling scoop

Information to be Derived: Location and orientation of the CACO01 CoastCam cameras; topography and bathymetry of the beach and nearshore region in view of the camera.

Summary of Activity and Data Gathered: March 4: 0) Established single-point localization using pre-established reference points in the parking lot 1) Measured location of CACO01 cameras with GNSS 2) Deployed plywood targets at several locations within view of cameras, recorded locations with GNSS, moved them several times 3) Conducted foot survey of beach in view of camera with GNSS 4) Collected sediment samples for analysis. March 6: 0) Deployed aeropoint targets 1) Collected aerial imagery to map subaerial beach in view of cameras using kitesurfing kites March 10: Conducted bathymetric mapping of nearshore region in view of cameras with echosounder attached to autonomous vessel built by Peter Traykovski of WHOI (has ppk GNSS system attached as well)

Staff: Jonathan Borden, Sandra Brosnahan, Eric Marsjanik, Marinna Martini, Jin-Si Over, Christopher Sherwood

Notes: FA is to collect GPS derived elevation data at the head of the meadows site. The team will run transects on the beach, and place aeropoint targets in view of the ARGUS camera system.
Three field days: foot survey and camera targets on March 4, kite survey on March 6, bathy survey on March 10.

PPK GPSAn 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. The AeroPoints have an internal GPS that are uploaded and post-processed in the Propeller network. Navigation
