In an effort spanning the Natural Hazards and Ecosystems Mission Areas, pilots from the Saint Petersburg and Woods Hole Coastal and Marine Science Centers collect imagery data using Unmanned Aerial System (UAS) while personnel from the Wetlands and Aquatic Research Center (WARC) conduct ground-based site surveys of Pelican Island, Alabama.

For more than 15 years, the USGS has actively studied natural and human changes to the shoreline, beaches, and dunes at Fire Island.

USGS scientists retrieve and process samples from an ecological processing monitoring station. Each station includes a caged native mussel (shown attached to the buoy rope) and a sampler for measuring invertebrate consumers

 Coastal storms can severely alter the topography and ecosystems along heavily populated coastal regions. Seamless integrated elevation data for both land and submerged areas in Barnegat Bay, New Jersey, are fundamental to coastal planning of the northeastern U.S. Atlantic coast.

Storm and sea level rise scenario models, like the one shown here, can be used to explore the future. This model shows what Dauphin Island may look like 10 years from now if storms become stronger and more frequent (Passeri and others, 2018).

Examples of sulfide minerals that occur at hydrothermal vents and are being studied by Amy Gartman: (left to right) sphalerite, an ore of zinc that often contains iron ([Zn,Fe]S); cubes of pyrite, rich in iron (FeS₂); and covellite, containing copper and sulfur (CuS).The pyrite cubes are a little more than half an inch on a side.

The distribution of sediment textures within the study area. The bottom-type classification is from Barnhardt and others (1998) and is based on 16 sediment classes. The classification is based on four sediment units that include gravel (G), mud (M), rock (R), and sand (S). If the texture is greater than 90 percent, it is labeled with a single letter.

Most underwater seismic data is collected from large research vessels; however, the shoreface environment is shallower than areas in which most seismic surveys occur. To get the information we need to assess changes in shoreface geology, we mount our seismic instruments on pontoon floats and deploy the instrument from the beach.

We mount our seismic instrument on pontoon floats with wheels. This setup is deployed from the beach and eventually towed behind our survey vessel.
