Three-dimensional view of the Hosgri fault 45 meters below the seafloor, revealing fault strands (black), and potential paths along the fault that fluid could follow (green/blue). The other colors represent different geologic layers.

Photographs taken during Tropical Storm Colin (left, June 6, 2016) and one day later (right) on Sunset Beach in the town of St. Pete Beach, Florida. Storm waves eroded the beach and dune, producing a cliff-like feature called a beach scarp. Continuous video collected during a storm could provide more information about the processes causing this coastal change.

Researchers survey Elwha River elevation and depths. Clockwise from upper left: setting up a traditional survey instrument above the river; measuring river depths from a kayak with sonar and GPS; walking the beach with GPS backpacks; and determining offshore depths using a personal watercraft with GPS and sonar.

The USGS strives to put coastal change data and information at the fingertips of users such as planners and emergency managers. The explicit goal is to enable users to integrate and apply USGS data and tools to address their specific needs. Online resources such as the Coastal Change Hazards (CCH) portal are designed with applied use of data in mind.

USGS ocean engineer Gerry Hatcher with the camera system he helped create for recording the precise time and geographic location of each air photo it takes. The system is mounted in the cargo compartment of a Cessna 182R airplane and takes photos through a window cut into a removable cargo door (right).

On October 6, 2016, scientists lower an instrument package on a taut-wire mooring into the canyon. The sediment trap (long funnel-shaped device) is designed to capture mud and sand carried in turbidity flows; the other sensors measure currents and suspended sediment.

Sediment trap is being prepared for deployment into Monterey Canyon offshore of Monterey, California.

Six USGS scientists presented their research at the 6th International Symposium on Deep-Sea Corals in September, 2016. This all-female force hailed from USGS centers in West Virginia, California, and Florida.

USGS is studying climate change impacts to U.S. Pacific and Arctic coasts. Alaska’s north coast is predominantly erosional, retreating on average about 1.4 meters per year.

USGS geologist Amy East was delighted to observe a Chinook salmon carcass upstream from two dams recently removed from the Elwha River in Washington State. River restoration has allowed salmon to reach upstream spawning grounds for the first time in more than a century.
