Resurrection Bay on August 8, 2016
Resurrection Bay on August 8, 2016. The water appeared calm in the shelter of the inner bay, but closer to the entrance, swells coming in from the Gulf of Alaska were breaking on a small beach where the three boaters had capsized.

USGS scientist measures water, sediment movement in coastal salt marsh
USGS scientist Zafer Defne measures water and sediment movement at Forsythe National Wildlife Refuge, New Jersey. Defne is co-author with Neil Ganju of a 2017 study on how to estimate coastal salt marshes’ potential longevity, based on their sediment budgets and the ratio of open water to vegetation.

Lake Powell
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 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.

Images of Madeira Beach, Florida, from video taken June 20, 2017
Views of Madeira Beach, Florida, produced from a 17-minute video shot on June 20, 2017. Left: Snapshot, or first frame of video. Right: Time-averaged image, sometimes called a “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during the 17-minute video.

“Variance” images derived from videos of beaches studied
“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.
