Sub seafloor structure of landslide in Santa Barbara Channel, CA
Example imagery revealing the sub-seafloor structure below a submarine landslide in the Santa Barbara Channel, offshore California. The base of the slide is traced in blue, and the near vertical black lines highlight shallow faults cutting through a zone of uplift located below the slide headscarp.

USGS Sediment Core Laboratory (AD)
USGS scientists collect core samples from estuaries, lakes, coasts, and marine environments to study a range of physical and chemical properties preserved in sediment or coral over time. They process and analyze these core samples at the Pacific Coastal and Marine Science Center’s Sediment Core Lab.

Science of Surfing
Join USGS Research Geologist and lifelong surfer Jon Warrick at the Pacific Coastal and Marine Science Center Santa Cruz as he discusses how coastal and ocean geoscience contributes to a better understanding of how waves form and behave as they approach the shore—critical information with a broad range of applications, not least of which is surfing!

Jet Ski Bathymetric Surveying (AD)
The USGS uses a variety of survey tools—including personal watercraft (jet skis) equipped with GPS and sonar—to measure how sandy coastlines change over time. Sandy coastlines are a valuable resource that protect human-made structures from waves, serve as habitat for important species, and provide a variety of recreational opportunities.

Nuvuk video camera 2 dark image
Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
