Visitors watched closely as Alicia Balster-Gee (in green vest) presented our research on marine geohazards in Alaska.

Members of the PCMSC Marine Minerals Team, including physical science technician Kira Mizell (center), took turns describing the importance of seafloor minerals.

Research geologist Jim Hein (right) gave a hands-on explanation of seafloor mineral deposits.

In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year.

View of the huge landslide at Mud Creek on the Big Sur coast, October 12, 2017. USGS is studying the landslide, collecting data and imagery that can be used to monitor changes. USGS provides the data to Caltrans, the California Department of Transportation, whose heavy equipment and earth movers are shown here.

USGS research geophysicist Danny Brothers (right) and colleagues examine the surface of a sediment grab sample just pulled onto the deck of the Canadian Coast Guard Ship John P. Tully. The sample was collected from the top of a mud volcano north of the border between southeast Alaska and British Columbia.

Scientists prepare to lower a piston corer off Haida Gwaii, British Columbia, to sample seafloor sediment near the Queen Charlotte-Fairweather fault. Expedition scientists are studying layers of sediment in the cores they collected to identify and determine ages of past earthquakes along the fault.
