Time-lapse photos taken from the northeast side of the Lied Bridge on the Platte River at South Bend near streamflow-gaging station 06805500. Photos taken every hour from April 14, 2011 to Aug. 6, 2012.

Time-lapse photos taken from the a camera on the upstream side of abandoned concrete bridge piers facing north toward State Highway 92 from June 1 to Aug. 6, 2012.

This time-lapse is shot on the Hood Canal Wa., over the course of a typical groundwater sampling field day. We were investigating the impacts of a macrotidal tide range on the geochemistry of submarine groundwater discharge.

Flooding costs the United States more than $7 billion per year and claims more than 90 lives annually. During the Spring and Summer of 2011, the central U.S. experienced epic flooding, while Hurricane Irene followed by Tropical Storm Lee caused severe flooding in the east and northeastern U.S, setting numerous flood records at USGS streamgages.

The United States has 169 active volcanoes. More than half of them could erupt explosively, sending ash up to 20,000 or 30,000 feet where commercial air traffic flies. USGS scientists are working to improve our understanding of volcano hazards to help protect communities and reduce the risks.

This fast paced, one minute trailer, promotes the award winning USGS video ‘Tracking Pacific Walrus’

Summer ice retreat in the Chukchi Sea between Alaska and Russia is a significant climate change impact affecting Pacific Walruses, which are being considered for listing as a threatened species. This twelve minute video follows walruses in their summer sea ice habitat and shows how USGS biologists use satellite radio tags to track their movements and behavior.
