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.

Lower Tubbs Island is a tidal marsh near Midshipman Point in northern San Pablo Bay, California, and is part of the San Pablo Bay National Wildlife Refuge. Historically, Tubbs Island was used as a club for duck hunters, protected by levees that could be opened with the tides to release salt water into the sloughs. In 1969, it was purchased by the Natu
