The USGS Utah Water Science Center and the Woods Hole Coastal and Marine Science Center conducted a collaborative geophysical research effort within Lake Powell, UT-AZ to map the bathymetry of the lake and characterize shallow sediment deposition near the mouths of the San Juan and Colorado Rivers.

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.

Example of lidar-derived metric products of canopy structure. A) Image showing an area characterized by varied forest strands.  (Red box shows from where profile data in E area taken.) B) Lidar-derived maximum canopy height.  C) Lidar-derived height of low- to medium-height vegetation beneath the overstory canopy.

(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.
