After surveying and analyzing centuries of evidence in the floodplain of the lower Roanoke River, USGS researchers, along with colleagues from the universities of Wisconsin and North Carolina, have developed a highly accurate estimate of sediment deposition amounts along the course of the river over three timescales — annual, decadal, and centennial.
The latest edition of the National Land Cover Dataset (NLCD 2011) for Alaska is now publicly available.
A new U.S. Geological Survey study shows how plants’ vulnerability to drought varies across the landscape; factors such as plant structure and soil type where the plant is growing can either make them more vulnerable or protect them from declines.
The President’s fiscal year 2016 budget request for the U.S. Geological Survey is $1.2 billion, an increase of nearly $150 million above the FY 2015 enacted level.
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. See diagram below for geographic coverage.
ANCHORAGE, Alaska 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.
ANCHORAGE, Alaska — In a new polar bear study published today, scientists from around the Arctic have shown that recent generations of polar bears are moving towards areas with more persistent year-round sea ice.
As part of President Obama's Climate Action Plan, research funding will provide land and wildlife managers with tools to adapt to climate change
A newly released interactive California Drought visualization website aims to provide the public with atlas-like, state-wide coverage of the drought and a timeline of its impacts on water resources.
The persistence of an already rare aquatic insect, the western glacier stonefly, is being imperiled by the loss of glaciers and increased stream temperatures due to climate warming in mountain ecosystems, according to a new study released in Freshwater Science.
Climate change could lengthen the growing season, make soil drier and decrease winter snowpack in the Lake Michigan Basin by the turn of the century, among other hydrological effects.
A pioneer in mapping global land cover change and the team behind the United States’ most advanced land surface mapping satellite have both been honored with the 2014 William T. Pecora Award for achievement in Earth remote sensing.
