Alaska is one of the most volcanically active regions on Earth, located at the far northern border of the Pacific Ocean, a vast, rugged area of critical importance to global commerce and national security.

Alaska has dozens of active volcanoes, some which erupt explosively multiple times a year. Learn how the scientists at the Alaska Volcano Observatory (AVO), which turns 20 in April, help prevent these hazards from becoming disasters.

A 20-year U.S. Geological Survey (USGS) study documents that recent changes in the quality and availability of sea ice in northern Alaska are the most likely explanation for a decrease in maternal polar bear denning on sea ice and an increase of denning on land. The results of the peer-reviewed study by the USGS Alaska Science Center in Anchorage were just published online in the journal

An article by U.S. Geological Survey (USGS) scientists on documentation of coastal land loss, lake expansion and drainage in Alaska from 1955 - 2005 was recently published in the July issue of Geology, a Geological Society of America publication.

The U. S Geological Survey (USGS) was recently asked by the U.S. Fish & Wildlife Service (USFWS) to evaluate the status of Marbled Murrelets in Alaska and British Columbia.
