The 3DR Solo with GoPro Hero4 camera and gimbal. Coming to a survey area near you soon. Photo credit: Shawn Harrison, USGS. This photo was taken during USGS unmanned aerial systems (drone) pilot training. Two training sessions were held - one in February-March 2017 in Santa Cruz, California and the second in April 2017 in Gainesville, Florida.

Estimated and measured ocean depths (bathymetry) from Madeira Beach, Florida. Each panel shows same geographic area. m = meters. Left: Snapshot transformed from original oblique camera view to overhead “map” view. Middle: Bathymetry estimated by applying cBathy algorithm to July 2017 video imagery. Right: Bathymetry measured with sonar in February 2017.

The R/V Muddy Waters lends itself to be a versatile survey launch and assistance vessel for the deployment and retrieval of inshore moorings and scientific sensor platforms. The boat can easily be towed to location by a full sized pickup truck and is easily launched and retrieved for fast mobilization after storm events or other rapid response surveys.
