USGS and Geological Survey of Canada scientists sample sediment cores collected from the sea floor along the Queen Charlotte Fault. This was taken while they were working with (or in) the Geological Survey of Canada.

The natural oil seep in this photo is located in Pescadero Creek County Park, where the Canyon Trail crosses Tarwater Creek. The oil is black, has a taffy-like consistency, and smells like motor oil.

The Half Moon Bay oil field is one of the oldest oil fields in California and was first developed during the 1880s. Since then, the field has produced an estimated 60,000 barrels of oil from about 19 wells.

Photograph of Carmel River near the Sleepy Hollow reach. San Clemente Dam was built on Carmel River in 1921 to supply water locally. After being declared seismically unfit, plans to remove the dam began. It was completely removed in 2015.

Orthomosaic images of Matanzas, Florida, from (a) before and (b) after Hurricane Matthew, and (c) a digital elevation model (DEM) showing the associated topographic change. Note, these results were produced by applying Structure-from-Motion (SfM) to NOAA oblique photographs, but similar results can be obtained using UAS aerial imagery.
