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. 
 

Bruce Molnia, senior science advisor with the USGS National Civil Applications Program, explains how he uses new technological advances to inform his study of the relationship between the surfaces and beds of glaciers and how new technology allows scientists to ask — and potentially answer — new questions.

Barter Island sits at the top of the Arctic National Wildlife Refuge in Alaska, and with the Arctic facing quickly rising temperatures, USGS wants to investigate what’s causing the North Slope bluffs to erode so quickly.

This time-lapse of Barter Island in Alaska during three summer months in 2014, shows the pack ice melting and the subsequent effects to the beach and permafrost cliffs from storms and summer temperatures. This camera sat on a fallen snow fence to capture storm events.

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.

Spring 2014. USGS scientists conduct a health evaluation of a young male polar bear in the Arctic as part of the annual southern Beaufort Sea population survey. The bear is sedated for approximately an hour while the team records a variety of measurements and collects key biological samples.

"1964 Quake: The Great Alaska Earthquake" is an eleven minute video highlighting the impacts and effects of America's largest recorded earthquake. It is an expanded version of the four minute video "Magnitude 9.2". Both were created as part of USGS activities acknowledging the fifty year anniversary of the quake on March 27, 2014.

Magnitude 9.2: The 1964 Great Alaska Earthquake is a short video relating how the largest quake in U.S. history had profound and lasting impacts on our lives. The video features USGS geologist George Plafker who, in the 1960's, correctly interpreted the quake as a subduction zone event.

Rapidly changing glaciers in Alaska demonstrate tight physical and ecological linkages with downstream ecosystems that bridge the icefield-to-ocean continuum.

This fast paced, one minute trailer, promotes the award winning USGS video ‘Tracking Pacific Walrus’

Summer ice retreat in the Chukchi Sea between Alaska and Russia is a significant climate change impact affecting Pacific Walruses, which are being considered for listing as a threatened species. This twelve minute video follows walruses in their summer sea ice habitat and shows how USGS biologists use satellite radio tags to track their movements and behavior.

Female Pacific walruses and their calves traditionally spend summers far from shore, diving for benthic invertebrates over the shallow continental shelf waters of the Chukchi Sea. These female walruses and their calves prefer to rest between forage bouts on sea ice drifting above their feeding grounds.

In order to study sea otters in the wild, research divers on the Pacific Nearshore Project must brave frigid waters from Alaska to California. Here's an explanation of how this special equipment works.

During the course of our research on walruses hauled out near Point Lay in

early September, USGS obtained aerial video footage of the

walrus aggregation.  This footage was taken from an altitude of 4,000' with

a Cineflex camera by Daniel Zatz, of Zatzworks, on contract to USGS for

How do you catch a sea otter? Very carefully. Researchers must use high-tech equipment and teamwork in order to safely capture these marine mammals and collect blood samples and conduct health exams as part of the Pacific Nearshore Project.

American and Canadian scientists head north on a collaborative expedition to map the Arctic seafloor and gather data to help define the outer limits of the continental shelf. Each coastal nation may exercise sovereign rights over the natural resources of their continental shelf.
