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.

“Variance” images derived from the same videos used in the studies. Left, Madeira Beach; right, Cowells Beach. In a variance image, the more variation in light intensity at a given pixel, the brighter the value assigned to that pixel. Bright areas indicate many changes in light intensity, caused by a lot of movement.

Topographic-change image produced by comparing 3D map derived from May 27 air photos with that derived from June 13 air photos. Note that material has eroded from the seaward edge of the toe (yellow and orange tones), and material has built up on beaches to either side of the slide (blue tones).
