USGS scientific programmer Tarandeep Kalra talks to children about ocean modeling.

“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.

Close-up views of the toe of the Mud Creek landslide created from air photos taken May 27 (top), June 13 (middle), and June 26 (bottom). Caltrans built roads on top of the slide for assessment and monitoring activities.

Topographic-change image produced by comparing 3D map derived from May 27 air photos with that derived from June 13 air photos. Note that material has eroded from the seaward edge of the toe (yellow and orange tones), and material has built up on beaches to either side of the slide (blue tones).

USGS pilot Sandy Brosnahan and Senate Pro Tempore Marc Pacheco discuss the use of Umanned Aerial Systems (UASs, also known as drones) to collect data in coastal environments.

Examples of sediment dynamics offshore of barrier islands include the development and erosion of shoals, tidal deltas, and sand ridges.

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.
