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.

An interdisciplinary USGS team is conducting research and developing tools to identify suitable coastal habitats for species of concern, such as the piping plover (Charadrius melodus), under a variety of sea-level rise scenarios.

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.

Authigenic carbonate supplies the foundation for deep-sea corals, including colonies of bubblegum corals (Paragorgia) seen here. 
 

(Top) Methane plumes at the Norfolk Canyon seeps (~1600 meters or 5250 feet) were detected using the EK60 sonar. The water column plumes are shown above the sub-seafloor structure as imaged by high-resolution multichannel seismic data acquired by the USGS and processed by J. Kluesner.
