Heat Accelerates Dry in California Drought



Released: 5/28/2015 1:56:43 PM
Although record low precipitation has been the main driver of one of the worst droughts in California history, abnormally high temperatures have also played an important role in amplifying its adverse effects, according to a recent study by the U.S. Geological Survey and university partners.

Hydraulic Fracturing (Frac) Sand Sources and Production in the United States



Released: 5/27/2015 12:20:58 PM
Newly released research from the U.S. Geological Survey describes U.S. hydraulic fracturing (frac) sand deposits and their locations, and provides estimates of frac sand production, consumption, and reserves. A companion map of producing and potential frac sand and resin-coated sand source units in the conterminous U.S. is also included.

Mammoths Reached the California Channel Islands Much Earlier Than Previously Thought



Released: 5/26/2015 10:57:32 AM
Recently, U.S. Geological Survey researchers and partners working in California’s Channel Islands National Park discovered mammoth remains in uplifted marine deposits that date to about 80,000 years ago, confirming a long-held but never proven hypothesis that mammoths may have been on the Channel Islands long before the last glacial period 25,000 to 12,000 years ago.

Long-term Prognosis for Florida Manatees Improves



Released: 5/20/2015 12:11:31 PM
The risk of extinction for the endangered Florida manatee appears to be lower, according to a new U.S. Geological Survey led study.

Louisiana Quads Add Trails and Survey Data



Released: 5/20/2015 9:30:00 AM
Several of the 812 new US Topo quadrangles for Louisiana now display public trails along with improved data layers.

Atmospheric Release of BPA May Reach Nearby Waterways



Released: 5/18/2015 12:05:00 PM
Water contamination by hormone-disrupting pollutants is a concern for water quality around the world.

Genetics Provide New Hope for Endangered Freshwater Mussels



Released: 5/18/2015 8:01:51 AM
A piece of the restoration puzzle to save populations of endangered freshwater mussels may have been found, according to a recent U.S. Geological Survey led study.

New Mineral Science Shows Promise for Reducing Environmental Impacts from Mining



Released: 5/12/2015 10:00:00 AM
Mining companies, land managers, and regulators now have a wealth of tools to aid in reducing potential mining impacts even before the mine gets started.

Boom and Bust in the Boreal Forest: Climate Signals Seen in Bird Populations



Released: 5/11/2015 3:00:00 PM
Weaving concepts of ecology and climatology, recent interdisciplinary research by USGS and several university partners reveals how large-scale climate variability appears to connect boom-and-bust cycles in the seed production of the boreal (northern conifer) forests of Canada to massive, irregular movements of boreal birds.

The Chemistry of Waters that Follow from Fracking: A Case Study



Released: 5/11/2015 8:49:26 AM
In a study of 13 hydraulically fractured shale gas wells in north-central Pennsylvania, USGS researchers found that the microbiology and organic chemistry of the produced waters varied widely from well to well.

Asian Carp Would Have Adequate Food to Survive in Lake Erie



Released: 5/6/2015 9:15:00 AM
If invasive bighead carp and silver carp spread into Lake Erie, there would be enough food available for these species of Asian carp to survive, according to a new study by the U.S. Geological Survey.

Shorebird Science? iPlover is the App for That



Released: 5/4/2015 8:06:11 AM
The latest tool designed to help manage the threatened piping plover is only a download away; iPlover is the first smartphone data collection application developed by the U.S. Geological Survey and will help those managing plover populations.

Dam Removal Study Reveals River Resiliency



Released: 5/1/2015 2:00:00 PM
More than 1,000 dams have been removed across the United States because of safety concerns, sediment buildup, inefficiency or having otherwise outlived usefulness.

Burmese Python Habitat Use Patterns May Help Control Efforts



Released: 4/28/2015 9:00:00 AM
The largest and longest Burmese Python tracking study of its kind -- here or in its native range -- is providing researchers and resource managers new information that may help target control efforts of this invasive snake, according to a new study led by the U.S. Geological Survey.
