New Maps for Texas and Oklahoma Released



Released: 4/7/2016 9:30:00 AM
New US Topo maps for Texas and Oklahoma are now available in the USGS Store for free download. One of the main improvements is the inclusion of the U.S. Census Bureau’s Topologically Integrated Geographic Encoding and Referencing (TIGER) road data.

Alaska Still a Likely Portal for Avian Influenza



Released: 4/5/2016 12:00:00 PM
ANCHORAGE, Alaska — The U.S. Geological Survey released additional evidence that western Alaska remains a hot spot for avian influenza to enter North America. The new report announces that while no highly pathogenic avian influenza viruses have been found in Alaska, the state remains an important area to monitor due to migratory bird flyways from North America and Eurasia that overlap the region.

FORT COLLINS, Colo. – From restoring the sagebrush sea to rejuvenating watersheds and landscapes after fires, ecosystem restoration can bear substantial economic fruit for local, state and national economies, according to a USGS study published today.

Cold Mountain Streams Offer Climate Refuge:



Released: 4/4/2016 3:15:00 PM
A new study offers hope for cold-water species in the face of climate change. The study, published today in the Proceedings of the National Academy of Sciences, addresses a longstanding paradox between predictions of widespread extinctions of cold-water species and a general lack of evidence for those extinctions despite decades of recent climate change.

Despite Long-Lasting Pollutants, Ospreys Thrive in US' Largest Estuary



Released: 4/4/2016 9:44:42 AM
The world's largest breeding population of ospreys is coping well with the long-lasting residues of toxic chemicals that were banned decades ago but remain in the Chesapeake Bay food chain at varying levels, such as the pesticide DDT and insulating chemicals known as PCBs.

Bat with white-nose syndrome confirmed in Washington state



Released: 3/31/2016 2:00:00 PM
Wing damage from fungus in little brown bat. These little brown bats in a NY cave exhibit the fuzzy white muzzles associated with the fungus that causes white-nose syndrome. The USGS National Wildlife Health Center conducts a bat autopsy as part of its efforts to study the fungus that causes white-nose syndrome in bats. A healthy, banded little brown bat hangs out in a cave. Photographer - Paul Cryan, USGS OLYMPIA, Wash. – White-nose syndrome (WNS) has been confirmed in a little brown bat (Myotis lucifugus) found near North Bend – the first recorded occurrence of this devastating bat disease in western North America. The presence of this disease was verified by the U.S. Geological Survey’s National Wildlife Health Center.

Study Shows Cold and Windy Nights Physically Drain Mangy Wolves

Hot Days Can Trigger Yosemite Rockfalls



Released: 3/28/2016 11:00:00 AM
After more than three years of monitoring the towering granite cliffs of Yosemite National Park, scientists have new insights into a potentially important mechanism that can trigger rockfalls in the park. Although many conditions can trigger rockfalls, some rockfalls are more likely to happen in the hottest part of the day, during the hottest part of the year.

First-Ever Maps to Show Induced and Natural Earthquake Hazards -- Press Conference



Released: 3/24/2016 9:09:30 AM
On March 28, USGS scientists will release a report and the first-ever maps showing potential ground-shaking hazards from both human-induced and natural earthquakes. In the past, USGS maps only identified natural earthquake hazards.

Drought and Management Actions Affect World Waterway--the Rio Grande



Released: 3/22/2016 2:19:26 PM
New research can help water managers along the Rio Grande make wise decisions about how to best use the flow of a river vital for drinking water, agriculture and aquatic habitat. These studies also show how conditions from the prolonged drought in the West have affected the Rio Grande watershed.

Experts Launch Project to Assess Drought Effects on Ecosystems and How Communities Can Adapt:



Released: 3/22/2016 7:00:00 AM
RESTON, Va. — A new public-private research collaboration supported by the U.S. Geological Survey will tackle how to best cope with the increasing droughts of the future.

Eastern Monarch Butterflies at Risk of Extinction Unless Numbers Increase



Released: 3/21/2016 7:30:59 AM
Long-term declines in the overwintering Eastern population of North American monarch butterflies are significantly increasing their likelihood of becoming extinct over the next two decades, according to Scripps Institution of Oceanography at UC San Diego and U.S. Geological Survey research published today.

USGS Partners with European Space Agency to Deliver Copernicus Earth Data



Released: 3/15/2016 2:24:32 PM
The U.S. Geological Survey and the European Space Agency (ESA) have established an innovative partnership to enable USGS storage and redistribution of Earth observation data acquired by Copernicus program satellites.

What a Drag: The Global Impact of Bottom Trawling



Released: 3/14/2016 1:00:00 PM
Recent scientific work outlines the severe consequences the practice of bottom trawling has on loose sediment on the ocean floor. Bottom trawling is a widespread industrial fishing practice that involves dragging heavy nets, large metal doors and chains over the seafloor to catch fish. Although previous studies documented the direct impacts of bottom trawling on corals, sponges, fishes and other animals, an understanding of the global impact of this practice on the seabed remained unclear until now. The first calculation of how much of the seabed is resuspended (or stirred up) by bottom-trawling shows that the sediment mass is approximately the same amount of all sediment being deposited on the world’s continental shelves by rivers each year (almost 22 gigatons).

Up to 70 Percent of Northeast U.S. Coast May Adapt to Rising Seas



Released: 3/14/2016 12:00:00 PM
Much of the coast from Maine to Virginia is more likely to change than to simply drown in response to rising seas during the next 70 years or so, according to a new study led by the U.S. Geological Survey. The study is based on a new computer model that captures the potential of the Northeast coast to change, driven by geological and biological forces, in ways that will reshape coastal landscapes.

Fire and Ice: Gauging the Effects of Wildfire on Alaskan Permafrost



Released: 3/14/2016 8:51:00 AM
USGS scientists, in collaboration with researchers at the University of Minnesota and University of Alaska Fairbanks, have mapped belowground permafrost in areas of Alaska that have been affected by wildfire, years-to-decades after the fires occurred.
