Diana McCandless of the Washington State Department of Ecology pauses for a moment, on the beach around the point and to the east of the mouth of Elwha River. McCandless is part of a team of scientists from WA State and the USGS who are periodically mapping the delta and beach areas near the mouth of the Elwha River.

USGS and Washington State Department of Ecology scientists are geared up and ready to start a topographic survey at the mouth of the Elwha River, using handheld computers and backpack-mounted GPS equipment.

Natural Bridges State Beach, shown here in the middle of the photo, is nestled amongst coastal neighborhoods in the southwestern part of Santa Cruz, California. View is looking south. The offices of the USGS Pacific Coastal and Marine Science Center are just a few hundred feet north, outside the bottom portion of the photograph.

Elkhorn Slough is a tidal river delta, salt marsh, and estuary in Monterey County, California. It is near the community of Moss Landing and is fed by Carneros Creek.

USGS scientists produced an animated GIF in coordination with the California Department of Transportation (Caltrans) re-opening of State Highway 1 through Big Sur on July 18, 2018. In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route with rocks and dirt more than 65 feet deep.

For a short study period, two video cameras overlooked the coast from atop the coastal bluff of Barter Island in northern Alaska. The purpose was to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

USGS oceanographer Li Erikson speaks at a community outreach event on Barter Island, Alaska, to present results from earlier USGS studies and to discuss ongoing USGS research.

USGS scientist Cordell Johnson points to the Raspberry Shake, a sensitive instrument used to detect ground shaking. Johnson mounted the Raspberry Shake to an aluminum pole which he will then drive into the ground to bury the instrument beneath the tundra. This process will help isolate it from the wind.

This device, called a Raspberry Shake, is a sensitive instrument used to detect ground shaking. It is being carefully buried in this shallow hole in the tundra, to isolate it from wind.
