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.
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.
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.
Alder, aspen, birch, elm, maple and oak are some of the most popular trees in North America. But it might come as a surprise that aspen, with their iconic white bark and beautiful autumn colors, have the largest range of any tree on the continent – one that extends from Alaska to Mexico and Vancouver to Maine, including almost every elevation in between.
WASHINGTON—The President’s fiscal year (FY) 2017 budget request for the U.S. Geological Survey reflects the USGS's vital role in addressing some of the most pressing challenges of the 21st Century by advancing scientific discovery and innovation.
Reston, VA – Inland capture fisheries are much more crucial to global food security than realized, according to the first global review of the value of inland fish and fisheries.
The U.S. Geological Survey is implementing new measures that will improve public access to USGS-funded science as detailed in its new public access plan.
Scientists from the National Park Service and the U.S. Geological Survey have reconstructed the recent migration history of ponderosa pine trees in the central Rocky Mountains.
Using statistically modeled maps drawn from satellite data and other sources, U.S. Geological Survey scientists have projected that the near-surface permafrost that presently underlies 38 percent of boreal and arctic Alaska would be reduced by 16 to 24 percent by the end of the 21st century under widely accepted climate scenarios.
A coalition of research institutions and fish and wildlife agencies this week unveiled a new online tool for use by local decision-makers, conservation managers, land trusts, regional planners, landowners and community leaders in Massachusetts who are interested in taking action in response to climate change.
The U.S. Geological Survey announced today that it has made part of a huge national repository of geographically referenced USGS field photographs publicly available. USGS geographers developed a simple, easy-to-use mapping portal called the Land Cover Trends Field Photo Map.
According to new U.S. Geological Survey research springs and marshes in the desert outside Las Vegas expanded and contracted dramatically in response to past episodes of abrupt climate change, even disappearing altogether for centuries at a time when conditions became too warm.
