David Pelunis-Messier and Milton Roberts navigating on the Tanana River, a main tributary of the Yukon River. The two are taking part in the Yukon River permafrost study.
Variously shaped fields of crops decorate the rich Canterbury Plains on New Zealand's South Island. This 2015 Landsat image shows the farmland abutting the Waimakariri River that winds down toward the city of Christchurch and ultimately the Pacific Ocean.

Jay Hootch, former employee of Yupitt of Andreafski, drills to take winter chemistry samples to be used in a permafrost loss study in the Yukon River Basin.
Heading out to take water chemistry samples for a study on permafrost in the Yukon River Basin. The study examined the chemical and hydrological changes occurring in the basin due to permafrost loss.
USGS staff dig snowpits to evaluate the snow structure after a wet snow avalanche cycle. This helps identify weak layers responsible for wet slab avalanches along the Going-to-the-Sun Road in Glacier National Park.
Sioux Falls, SD. — Climate change may pose a substantial future risk for sagebrush habitat in southwestern Wyoming, and thus adversely affect the regional summer habitat and nesting areas of sage-grouse, according to a new study by the United States Geological Survey.
Climate change will impact many indigenous communities and may well endanger sacred and traditional living sites, cultural practices, local forests and ecosystems, traditional foods and water quality.
Kristin Timm, a designer with the Interior Department's Alaska Climate Science Center and the University of Alaska Fairbanks Scenarios Network for Alaska and Arctic Planning, is among 10 designers who were recently recognized internationally for excellence in science communication.
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.
