Satellite image from the USGS/NASA Landsat-8 satellite showing the eruption cloud at Pavlof Volcano on November 15 at 12:46 pm AKST (21:46 UTC). This is just a portion of the eruption cloud, which extended for more than 250 miles to the northwest at the time this image was collected. In this image, the distance from the erupting vent to the upper left corner of the image...

This video was edited and compiled from raw footage recorded by a camera equipped radio collar that was put on a female polar bear in the Beaufort Sea during April 2014 by the US Geological Survey. This new type of camera technology was developed by videographer Adam Ravetch with the support of the World Wildlife Fund. The video, which is the first ever from a free-ranging...

ANCHORAGE, Alaska — In the 20th century, Baranof Island in Southeastern Alaska has drawn attention for its gold, chrome and nickel deposits, timber industry, potential activity of the dormant Mount Edgecumbe volcano, and for numerous commercially developed hot springs.
The U.S. Geological Survey today released the North Pacific Pelagic Seabird Database — a massive online resource compiling the results of 40 years of surveys by biologists from the United States, Canada, Japan and Russia. The database documents the abundance and distribution of 160 seabird and 41 marine mammal species over a 10 million-square-mile region of the North Pacific.
Greenhouse gas emissions remain the primary threat to the preservation of polar bear populations worldwide. This conclusion holds true under both a reduced greenhouse gas emission scenario that stabilizes climate warming and another scenario where emissions and warming continue at the current pace, according to updated U.S. Geological Survey research models.
North America may have once been attached to Australia, according to research just published in Lithosphere and spearheaded by U.S. Geological Survey geologist James Jones and his colleagues at Bucknell University and Colorado School of Mines.
ANCHORAGE, Alaska — A team of scientists led by the U.S. Geological Survey found that polar bears, increasingly forced on shore due to sea ice loss, may be eating terrestrial foods including berries, birds and eggs, but any nutritional gains are limited to a few individuals and likely cannot compensate for lost opportunities to consume their traditional, lipid-rich prey—ice seals.
ANCHORAGE, Alaska — In a new study published today, scientists from the U.S. Geological Survey and U.S. Fish and Wildlife Service harnessed a new type of DNA technology to investigate avian influenza viruses in Alaska.
Frozen bodies of ice cover nearly 10 percent of the state of Alaska, but the influence of glaciers on the environment, tourism, fisheries, hydropower, and other important Alaska resources is rarely discussed.
