Natural Breakdown of Petroleum Underground Can Lace Arsenic into Groundwater

Released: 1/26/2015 9:36:01 AM
In a long-term field study, U.S. Geological Survey (USGS) and Virginia Tech scientists have found that changes in geochemistry from the natural breakdown of petroleum hydrocarbons underground can promote the chemical release (mobilization) of naturally occurring arsenic into groundwater.

More Global Topographic Data to Aid Climate Change Research

Released: 1/26/2015 9:00:00 AM
Improved global topographic (elevation) data are now publicly available for most of Asia (India, China, southern Siberia, Japan, Indonesia), Oceania (Australia, New Zealand), and western Pacific Islands.

USGS Statement Regarding Avian Flu Found in Washington State Green-Winged Teal

Released: 1/23/2015 5:55:02 PM
Some media are reporting that the Asian H5N1 strain of highly pathogenic avian influenza has now entered the United States. This is incorrect.

Culprit Identified in Decline of Endangered Missouri River Pallid Sturgeon

Released: 1/23/2015 1:30:21 PM
BOZEMAN – Pallid sturgeon come from a genetic line that has lived on this planet for tens of millions of years; yet it has been decades since anyone has documented any of the enormous fish successfully producing young that survive to adulthood in the upper Missouri River basin.

Melting Glaciers Increase the Flow of Carbon to Downstream Ecosystems

Released: 1/20/2015 1:00:00 PM
Melting glaciers are not just impacting sea level, they are also affecting the flow of organic carbon to the world’s oceans, according to new research that provides the first ever global-scale estimates for the storage and release of organic carbon from glaciers.

New Nebraska Maps Feature Trails

Released: 1/13/2015 10:00:00 AM
Newly released US Topo maps for Nebraska now feature trails provided to the USGS through a “crowdsourcing” project operated by the International Mountain Biking Association (IMBA).

Oso Landslide Research Paves Way for Future Hazard Evaluations

Released: 1/12/2015 1:00:00 PM
VANCOUVER, Wash. — The large landslide that occurred on March 22, 2014 near Oso, Washington was unusually mobile and destructive. The first published study from U.S. Geological Survey investigations of the Oso landslide (named the “SR530 Landslide” by Washington State) reveals that the potential for landslide liquefaction and high mobility are influenced by several factors, and the landslide process at Oso could have unfolded very differently (with much less destruction) if initial conditions had been only subtly different.

By Bike, Foot or Hoof: New Arizona Maps Feature Trails

Released: 1/7/2015 10:00:00 AM
Newly released US Topo maps for Arizona now feature mountain bike trails, segments of the Arizona National Scenic Trail and Public Land Survey System data.

Fewer Large Earthquakes in 2014

Released: 1/7/2015 9:00:00 AM
While the number of large earthquakes fell to 12 in 2014, from 19 in 2013, several moderate temblors hit areas relatively new to seismicity, including Oklahoma and Kansas, according to the U.S. Geological Survey.

Polar Bears Shifting to Areas with More Sea Ice -- Genetic Study Reveals

Released: 1/6/2015 2:00:00 PM
Editors: B-roll footage of polar bear research is available for your use.

Endangered Salmon Population Monitored with eDNA for First Time

Released: 1/5/2015 2:00:00 PM
CORVALLIS, Ore. — Scientists from the U.S. Geological Survey and Washington State University have discovered that endangered Chinook salmon can be detected accurately from DNA they release into the environment. The results are part of a special issue of the journal Biological Conservation on use of environmental DNA to inform conservation and management of aquatic species.

How Does White-Nose Syndrome Kill Bats?

Released: 1/5/2015 12:00:00 PM
For the first time, scientists have developed a detailed explanation of how white-nose syndrome (WNS) is killing millions of bats in North America, according to a new study by the U.S. Geological Survey and the University of Wisconsin.
