USGS Hawaiian Volcano Observatory field engineers upgrade a tiltmeter on Kīlauea Volcano's East Rift Zone. The upgrade consisted of switching the old analog instrument to a newer digital model. This tiltmeter is used to track magma movement within the volcano.

A wildfire ignited by lightning in the Okefenokee National Wildlife Refuge on April 6, 2017, is persisting into May. Hot, dry weather and extremely dry fuels are making the fire difficult to contain. As of May 22, the blaze, also called the West Mims Fire, had burned 152,478 acres.

As part of the Regional Stream Quality Assessments (RSQA), hydrologists, ecologists, and technicians did ecological surveys of aquatic biota and stream habitat. Here, an ecologist uses a net to collect a sample of aquatic invertebrates for ennumeration and identification.

Frame from video of Cowells Beach in Santa Cruz, California, showing “pixel instruments” measured continuously during the video and used to estimate different coastal processes. The blue dots represent an array of pixels used by a computer program called cBathy to estimate seafloor depths (bathymetry).

USGS ocean engineer Gerry Hatcher (left) and USGS postdoctoral oceanographer Shawn Harrison make adjustments to a computer controlling two video cameras on the roof of the Dream Inn, a 10-story hotel overlooking Monterey Bay in Santa Cruz, California. One camera looks eastward over Santa Cruz Main Beach and boardwalk, and the other southward over Cowells Beach.
