Despite recent changes to the growing season for plants in the Arctic, Alaska, caribou appear to have remained in sync with these changes over the last 30 years.
Tests of 75 private drinking water wells in Lycoming County, in north-central Pennsylvania, found water from most of the sampled wells contained concentrations of radon that exceeded a proposed, nonbinding health standard for drinking water. Smaller percentages of the wells contained concentrations of arsenic or methane that exceed existing drinking water standards.
Scientists can now predict which avian species are most sensitive to the increasingly dominant shrub habitat spreading across Alaska, a capability that will be useful for natural resource agencies in Alaska charged with managing these resources.
Human and bovine, or cattle, viruses were detected in a small percentage of some Great Lakes Basin streams, with human viruses more prevalent in urban streams and bovine viruses more common in streams in agricultural areas, according to a recent U.S. Geological Survey-led study.
Pasadena, Calif. – A new U.S. Geological Survey study offers a view into the past behavior of large earthquakes along the southern San Andreas Fault.
Philadelphia communities along the Schuylkill River and Darby Creek now have new tools to help inform residents of impending flooding. The U.S. Geological Survey recently installed three new streamgages in Manayunk, Eastwick, and downtown near 30th St., which will monitor water levels, and provide vital data used by emergency managers and flood forecasters to help protect lives and property.
A USGS analysis of New Jersey water quality trends found levels of total nitrogen and total phosphorus, which fuel algae blooms, declined or stayed the same at most stream sites between the 1970s and 2011. At all sites studied, chlorides from road salt increased over that time.
On March 1, a USGS study will be released that shows potential ground-shaking hazards in 2017 from both human-induced and natural earthquakes.
Joyce E. Williamson, a native of South Dakota and a South Dakota School of Mines and Technology alumna, was selected as the director of the newly formed U.S. Geological Survey Dakota Water Science Center. Williamson is located in the center’s Rapid City, South Dakota, office.
A better understanding of sediment and freshwater flow into Galveston Bay is now available from a new U.S. Geological Survey report, done in cooperation with the Texas Water Development Board, and the Galveston Bay Estuary Program.
Small variations in the density of the earth’s crust—undetectable to humans without sensitive instruments—influence where earthquakes may occur in the central United States. These new findings from the U.S. Geological Survey, published today in Nature Communications, may allow scientists to map where future seismicity in the center of the country is most likely.
