Dan Hoover takes a break near Moss Landing, California. Dan drives the all-terrain vehicle seen behind him to rapidly survey long sections of beach using precision GPS. 

The refrigerated sample repository of the USGS Pacific Coastal and Marine Science Center in Santa Cruz, CA includes easily accessible shelving space which can store thousands of samples.

Shawn Harrison surveys beach topography using a backpack equipped with precision GPS at Zmudowski State Beach, California. The fog-shrouded Moss Landing Power Plant looms in the background. 

USGS hydrologic technician Michael Allen collects streamflow data from the Boise River at streamgage station 13206000 using an acoustic Doppler current profiler.

USGS scientists measure water velocity, water quality, suspended sediment, and many other values to improve computer models of wetland changes in coastal National Park Service units, including Cape Cod National Seashore.

Shawn Harrison surveys beach topography using a precision GPS backpack on Twin Lakes State Beach, California. USGS researchers have measured coastal sediment supply and transport patterns in northern Monterey Bay for five years. Twice each year they survey the coast from Santa Cruz to Moss Landing with a variety of devices.

USGS scientist Nick Johnson isn’t afraid to get dirty. Here he is expressing green feces from a parasitic sea lamprey. DNA in the feces may help USGS scientists discover the identity of sea lamprey’s last meal. 

USGS scientists collect water samples for chemical analysis from an excavated pond in the NJ Pinelands.

A Valentine's Day 2017 view of Kīlauea Volcano's summit lava lake, here the surface of the lake is about 21 m (69 ft) below the vent rim. The lake diameter is about 255 m or 840 ft. Careful tracking of the amount of ash emitted by lake processes suggest an important new insight into the supply of magma to Kīlauea's summit. USGS Photo.
