USGS scientists working at laboratory fume hood

On April 12, the USGS, together with the American Fisheries Society (AFS), hosted a roundtable discussion with congressional staff centered on the impacts of extreme weather events like hurricanes, floods, droughts, and wildfires on inland fish. Scientists with the USGS National Climate Adaptation Science Center (NCASC) are investigating how climate-relate

Dead Run is an urban creek in Catonsville, Maryland, near Baltimore. Research has found that about half of the bed sediment originates as particulate matter on pavement that then is washed into the creek via storm drains.

Most of the lava flow (dark black) produced by the April 1868 Mauna Loa eruption can be seen in this aerial photo on the west (left) side of the prominent fault scarp, known informally as the Kahuku pali (formal names are Pali o Mamalu for the upper half and Pali‘okūlani for the lower half of the scarp).

Video: Clear skies and sunshine provided a spectacular view of Kīlauea Volcano's summit lava lake this morning. Spattering on the north side and center of the lake surface—a departure from its more common location on the southeast side of the lake—occasionally happens when the surface flow direction reverses.

Marshmallow-like formations were photographed on the Cannonball River at Regent, North Dakota (USGS streamgage 06350000) on April 3, 2018. Foam is produced naturally from organic material in the water in combination with turbulence resulting from water flowing over the weir.
