This 5 minute interview with polar researcher Carin Ashjian gives a glimpse into her study of oceanography and marine ecosystems in the Arctic.

Antarctic educator, Mark Walsh, created this video for the PolarTREC 2013 spring online professional development course. This video uses the concept of Density to explore how mountains are built as well as how to throw a good Cinco de Mayo party at McMurdo Station Antarctica. He uses the Dr. Samantha Hansen's Transantarctic Mountains work as an example of mountain building.

The Yale Climate Forum released this YouTube video on Permafrost in 2013. The causes and effects of melting permafrost are explained and linked to larger phenomena. Visit the Yale Climate Forum Website to learn more.

This short video provides an overview of the types of rocks found in Antarctica and what we can learn about Antarctica from polar geology. This video is designed to accompany the September 2008 issue of the free online magazine, Beyond Penguins and Polar Bears. The magazine is a professional development magazine for elementary teachers.

Researchers at the University of Alaska Fairbanks are studying the East Siberian Arctic Shelf region and finding the seafloor there holds vast stores of frozen methane and is showing signs of instability and widespread venting of the powerful greenhouse gas. In this video University of Alaska Fairbanks scientist Natalia Shakhova discusses the East Siberian Arctic Shelf area.

In an explosive clip from the BBC's landmark series, scientists drill into a frozen lake to ignite methane gas that is trapped in bubbles beneath the surface. Do greenhouse gases pose a signficant threat to our planet? Dr Iain Stewart assesses the dangers.

University of Alaska Fairbanks Professor Katey Walter Anthony takes us onto a frozen lake in Fairbanks, AK to demonstrate why methane gas has "exploded" onto the climate change scene.

From NASA, in this animation, the Arctic sea ice and seasonal land cover change progress through time, from September 1, 2009 when sea ice in the Arctic was near its minimum extent, through March 30, 2010. The animation plays at a rate of six frames per day or ten days per second.

This lecture introduces physical oceanography, the study of the physics of the world ocean.

This lecture discusses factors that affect seawater density, a most important quantity with implications for ocean circulation and productivity.
