Crews perform repairs on the Sperry Weather Station as part of Fire Operations in Glacier National Park. Information gathered by the USGS managed Sperry Weather Station are being used by regional fire managers to forecast fire weather and future fire behavior during the 2017 fire season.

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.

In early September 2017, Landsat 8 captured this image of what looked like an oil spill off the coast of Brazil, near Sao Paulo. The "oil" turned out to be a vast algal bloom that covered more than 100 km. This bloom was the result of a species of tiny dinoflagellate that multiplied quickly to produce astronomical numbers -- enough to color the ocean water.

Location 4. Sand dunes along this stretch of coast in Sargent, Texas, were overwashed by large waves during the storm. Sand from the beach and dunes is covering the roadway behind the dunes and which may be impassable. The predicted probability of overwash in this area was 94%.

Jim Duda, USGS hydrologic technician, installs a Rapid-Deployment Gauge near the Elizabeth River in Norfolk, Virginia, to monitor elevated water levels caused by Hurricane Jose. An RDG is a fully functional streamgage designed to be quickly deployed for real-time data monitoring of a stream or river in emergency situations.

USGS scientists Lisa Ashmore and Lee Bodkin collect water-quality samples on Lake Houston in response to the high flow conditions that resulted from Harvey.

USGS WERC researcher Julia Ersan gets prepared to release a hoary bat (Lasiurus cinereus) after capture and examination. USGS researchers are conducting multiple projects to learn about the ecology of Western bats, including long distance migrants like the hoary bat.

USGS scientist Jimmy Hopkins repairs a streamgage downstream of Addicks reservoir at Buffalo Bayou after flooding from Hurricane Harvey. This gauge is normally accessed on land from a platform on the side of a bridge.

USGS scientist Lisa Ashmore services a water-quality monitor on Lake Houston. These instruments stayed afloat and collected data throughout Harvey.
