Estimated and measured ocean depths (bathymetry) from Madeira Beach

Estimated and measured ocean depths (bathymetry) from Madeira Beach, Florida. Each panel shows the same area, m = meters. Left: Snapshot transformed to a bird’s-eye view. Middle: Bathymetry estimated using cBathy on July 2017 video images. Right: Sonar bathymetry measured in February 2017. Despite the five-month difference, both bathymetry 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.
