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...

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.
