Spattering is common in Kīlauea Volcano's summit lava lake, and consists of many large bursting gas bubbles. The fluid nature of the lake can be seen when lava hits the wall and flows downward like syrup. The thin, flexible nature of the crust is also shown here, as the bursting gas bubbles rip and fold the thin skin on the lake.

Elk are not concerned with our work. USGS and the Monterey Bay Aquarium Research Institute conducted tests of the feasibility of real-time eDNA monitoring at USGS streamgage 06190540 Boiling River at Mammoth,YNP, September 13, 2017.

The dramatic changes to the island caused by Irma, the strongest Atlantic hurricane on record, are shown in this pair of images from Landsat 8. Landsat uses shortwave-infrared, near-infrared, and green wavelengths to reveal those changes. The August 27 image shows healthy vegetation as bright green.

The Maine Office boat, "Miss Q", is parked next to the boat launch on Verona Island, ready to begin data collection on the Penobscot River. The crew was preparing to collect ADCP data (depth and velocity) as well as conductivity, temperature and depth profiles at various locations. In the background is the Penobscot Narrows Bridge and Fort Knox.

Construction of the McKelvey Building, or Building 15, was completed in the mid-1990s on the USGS Western Region campus in Menlo Park, California. It houses many different USGS teams, such as Pacific Coastal and Marine Science Center, Water Science Center, and Volcano Science Center, and features many state-of-the-art laboratories.
