Estimated and measured bathymetry offshore of Madeira Beach, 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. Despite being based on data collected 5 months apart, both bathymetric images show similar depths and features: a sandbar about 140 meters cross-shore, deepening to a trough at 100 meters, and shallowing to the shoreline at 50 meters.
