Building 1 formerly housed many different USGS groups, including the Western Coastal and Marine Geology team, but slowly has been leased out to other federal agencies like the Transportation Security Administration (TSA) and Veterans Affairs (VA). At the right is the Menlo Survey Federal Credit Union.

This instrument, the Edgetech SB-516 or "chirp", emits acoustic signals that penetrate the sediment on the seafloor. The reflected sound is recorded and is used to create a cross-section image, or profile, of the sub-bottom.

NOAA ship Reuben Lasker docked in San Francisco with the Bay Bridge in the distance. On October 21, leadership from NOAA, USGS, and BOEM met with the scientists and crew of the EXPRESS expedition to learn about the multi-agency cooperative research campaign.

A view of the mouth of the Klamath River where it meets the Pacific Ocean in northern California. The river runs from Oregon to California. Four dams along the Klamath are pending removal. USGS is studying coastal watershed response to dam removal, including long-term before-after/control-impact (BACI) studies.

USGS science crew from Pacific Coastal and Marine Science Center work together to get the vibracorer coring device in position to collect sediment core samples off San Francisco, California.

The Rossfelder P-5 vibracorer, with its polybuterate liner visible, is secured on the deck of the research vessel Bold Horizon, awaiting deployment off the coast of California just north of San Francisco. More liners are stored in a cage off to the side.

The USGS uses the Rossfelder P-5 vibracorer to collect deep-water sediment samples from the seafloor. Here, they are heading out offshore of San Francisco with the Golden Gate Bridge in the background.

The USGS Coastal and Estuarine Dynamics Group will be deploying a cross shore array at Pea Island, various intruments will be connected to the poles to measure oceanographic conditions

The crew of research vessel Bold Horizon with USGS science crew prepare to launch the Chirp sub-bottom profiler off the west coast near northern California and southern Oregon.

USGS scientists Nora Nieminski, Jenna Hill, and Brandon Nasr working to cap and secure a trigger core on deck. Trigger cores can provide important information about seafloor sediments just below the seafloor

USGS scientists Pete Dal Ferro and Jenny McKee securing a recently collected jumbo piston core (JPC) on the back deck of M/V Bold Horizon for preliminary core processing.

After recovery, the jumbo piston corer sits on the deck of research vessel Bold Horizon in its launch and recovery system. This muddy collar is removed to reveal the removable length of the core, which sits within a stiff plastic tube inside the metal tube.

USGS marine technician Jenny McKee prepares the jumbo piston corer for launching off research vessel Bold Horizon off the coast of California and Oregon. The corer will collect sediment samples from the seafloor. Scientists will examine the sediment to determine its age, character, and distribution. This area off the west coast of the U.S.
