Josh Logan operates a drone carrying a precision GPS and special camera to map the shore at Long Beach, Washington. USGS scientists used the same system for detailed mapping of beaches beside Monterey Bay, California.

Biologists identify species, count, measure length, and release thousands of fish each year to understand how fish use nearshore habitats.

Dead trees like the ones featured in this photo still provide valuable habitat for wildlife, including birds.

A fyke net or fish trap used for continuous sampling of nearshore fish in shallow waters. Fish swimming along the beach are stopped by a small-mesh net that guides them in to one of these two underwater fish traps that are set side by side. Researchers visit nets at least once a day to identify, count, and release fish.

The world's largest continuous hops-growing region by area is Hallertau, just north of Munich. More than 80 percent of Germany's hops come from this 42,000-acre stretch of fertile loess soil.

An underwater image of fish captured by a fyke net near Kaktovik, Alaska, Beaufort Sea, USA. The small silver fish with dark backs are young-of-year (age-0) Arctic cisco (Coregonus autumnalis) and the flatfish are Arctic flounder (Liopsetta glacialis).

This perched lava channel, which was as much as 150 feet (45 meters) above the ground, carried lava downslope from the Pu‘u ‘Ō‘ō Fissure D vent during episode 58 of Kīlauea Volcano's ongoing East Rift Zone eruption. The channel was the main path for lava between July and November 2007. Episode 58 continued until early March 2011.

Charcoal collected from under the base of a pāhoehoe flow in a black sooty zone over orange ash.  The black sooty zone represents the region where the vegetation was converted to charcoal.  The hammer is approximately 13 inches long. USGS photo by F. Trusdell.

To collect, identify and document these single-celled algae called desmids, USGS biologist Barry H. Rosen has traveled by airboat into the interior of Florida’s Loxahatchee National Wildlife Refuge, where decaying marsh grasses created a mosaic of peat soils and the soft, slightly acidic water where desmids grow.

This single-celled freshwater algae wasa collected as part of the first-ever study of the green algae family called desmids in Florida’s Loxahatchee National Wildlife Refuge, in the northern Everglades. USGS biologist Barry H.
