This video showcases the latest polar bear point-of-view footage to date along with an interview of the research scientist who is responsible for the project. Released in conjunction with a new scientific study led by the USGS. 
 

Unlike the South Pole, the geographic North Pole does not lie on a land mass. The Earth’s northern axis of rotation is in the Arctic Ocean, covered by shifting sea ice.



Landsat does not image the North Pole, which makes it an imperfect investigative tool for the detection of Santa’s workshop. 

Fire is the dominant ecological disturbance process in boreal forests (coniferous forests consisting mostly of pines, spruces, and larches) and fire frequency, size and severity are increasing in Alaska owing to climate warming.

This video presents a visualization of how the Atwood Building in Anchorage, Alaska, shook during the Mw 7.0 November 30, 2018, Anchorage, Alaska, earthquake. The building was instrumented by the U.S. Geological Survey to obtain data to study its behavior and performance during strong shaking.

This video presents a visualization of how the Frontier Building in Anchorage, Alaska, shook during the moment magnitude (Mw) 7.0 November 30, 2018, Anchorage, Alaska, earthquake. The building was instrumented by U.S. Geological Survey to obtain data to study its behavior and performance during strong shaking.

This video presents a visualization of how the BP Exploration Building in Anchorage, Alaska, shook during the moment magnitude (Mw) 7.0 November 30, 2018, Anchorage, Alaska, earthquake. The building was instrumented by U.S. Geological Survey (USGS) to obtain data to study its behavior and performance during strong shaking.

Exciting polar bear cam b-roll footage from the bear’s perspective from 2014, 2015, and 2016. The USGS Alaska Science Center Polar Bear Research Project conducts long-term research on polar bears to inform, local, state, national and international policy makers regarding conservation and management of the species and its habitat.

A team of USGS scientists spent two weeks in the isolated Glacier Bay National Park, exploring one of the fastest-moving faults in North America.
 

• Glacier Numerology – The how big, how long, how thick, how much, how often, of glacier science.
• Glacier Photography – While a picture may be worth a thousand words, a collection of images may tell a complete forensic story.

More than 7 million Landsat satellite images now available.

The distribution of water on the landscape influences many ecological functions such as the distribution of vegetation, soil development and the cycle of chemical nutrients. All of these functions are subject to change as a result of variations in the duration of soil water saturation and flow of water through the distributed channel networks of watersheds.

Approximately 25 to 50 percent of a living tree is made up of water, depending on the species and time of year. The water stored in trees has previously been considered just a minor part of the water cycle, but a study by University of Alaska Fairbanks scientists with support from the DOI Alaska Climate Science Center shows otherwise.

This video presents a visualization of shaking that was recorded in the Frontier Building in Anchorage, Alaska, during the Mw7.1 earthquake, January 24, 2016, Iniskin, Alaska. It exhibits how a tall building behaves and performs during strong earthquake shaking.

This short clip is representative of a large amount of video footage of an adult female polar bear, equipped with a point of view camera, that is used by scientists to study polar bear behavior and feeding rates.

This video presents a visualization of how the Atwood Building in Anchorage, Alaska, shook during the M7.1 January 24, 2016, Iniskin, Alaska, earthquake. The building was instrumented by U.S. Geological Survey to obtain data to study its behavior and performance during strong shaking.

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. 
 

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.
