Centrifuge Bowl Containing River Suspended Sediment for Analysis

A U.S. Geological Survey hydrologist holds a centrifuge bowl containing river suspended sediment for analysis of metals and organic chemicals. The sample was collected using a new in-field continuous-flow centrifugation technique to separate and collect suspended sediment from large volumes of water. The sample was collected on the Duwamish River, Washington in cooperation

Oso Landslide Computer Simulations

A large destructive landslide occurred near Oso, Washington on March 22, 2014. Computer simulations indicate that it could have behaved very differently (with much less mobility and consequent destructiveness) if the ground had been less porous and water-saturated. This video shows the results of two computer simulations. The first simulation shows computed landslide

Continuous Gas Monitoring Tracks Volcanic Activity at Mount St. Helens

Volcano gas geochemistry has been around for a long time. Scientists can make gas measurements using very large, very expensive Correlation Spectrometers or collect samples in the field and bring them back for analysis in the lab. But it’s possible we’re missing out on a lot of information because our monitoring capabilities don’t include continuous observation.

Elwha River flowing through former dam site during flood

USGS Hydrologist Chris Magirl captures image of the Elwha River flooding for the first time following dam removal. This location is just downstream of the former Elwha Dam which used to stand at the area near the top of the photograph.

Pend Oreille River in winter

The Kalispel Tribe in northeastern Washington is located along the Pend Oreille River, home to culturally important, cold-water fish, such as bull trout and cutthroat trout. In an ongoing study, USGS researchers are helping to identify cold-water refuges and develop a protection and restoration framework that will inform Kalispel Tribe natural resource managers involved in

Most species of migratory birds in the Northern Hemisphere make two long trips each year, one north for nesting and the other south for the winter. New information collected by USGS scientists shows that individuals of at least one species, the prairie falcon, make three separate long trips each year.
