A perspective model of the morphology and geologic framework near Petit Bois Island showing the relationships between seafloor features and the subsurface. The barrier islands rest on the island plaftorm. Petis Bois Pass and offshore shoals are clearly visible from the acoustic surveys. The bathymetry, sidescan sonar, and sediment

Tropical Storm Nate's predicted effect on Northern Gulf sandy shorelines, based on landfall as a Category 1 hurricane,  is shown at three intensities. Outer band:  Dune erosion. Middle band: Dune overwash. Inner band: Dune inundation, with potential flooding behind the dune. Credit: USGS Coastal Change Hazard Portal.

Joseph Terrano of the USGS St. Petersburg Coastal and Marine Science Center retrieves a sediment sample from under the marsh grass. Scientists installed several Net Sediment Tiles (NST) on the surface of the marsh to measure sediment deposition.

A rock breakwater and salt marsh planting act as the living shoreline structure along the Fog Point shoreline in Chesapeake Bay, Maryland.

Scanning Electron Microscope (SEM) images of fossilized diatom specimens (microfossils). Diatoms are microscopic phytoplankton (algae) that are found in aquatic environments all over the world. Plankton species have preferences for different water and environmental conditions, such as salt or fresh water, attaching to sand or vegetation, or river versus estuary.

“Variance” image produced from video shot at Madeira Beach, Florida, on June 20, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright bands parallel to shore where waves were breaking.
