Where Glaciers Meet the Sea: How a warming ocean might speed the loss of Greenland's ice
http://www.whoi.edu/oceanus/viewArticle.do?id=95850

Cherie Winner, Woods Hole Oceanographic Institution

This video describes how the normal thousands-of-years-long balance of new ice creation and melting due to ocean currents has been disrupted recently by warmer ocean currents. As a result, glacier tongues that overhang the interface between ice and ocean are breaking off and falling into the ocean.

Video length 3:21 minutes.

Teaching Tips

  • Could be used as part of an oceanography unit or a general unit on the Arctic and climate warming.

About the Science

  • The video describes how the normal thousands-of-years-long balance of new ice creation and melting due to ocean currents has been disrupted recently by warmer ocean currents.
  • Comments from expert scientist: This is a really nice video explaining why the Greenland glaciers have been accelerating in the last decade. The animation starts out with images from Greenland. Then the animation shows the steady state situation and contrasts this to the present situation, demonstrating why the glaciers are accelerating. The animations do an excellent job of presenting the physics of the problem.

About the Pedagogy

  • The animations are clear and illustrate very well the change in the glacier-ocean interface.
  • An OCEANUS article accompanies the video. It is accessible from the "Learn more on Oceanus magazine" link below the video or at http://www.whoi.edu/oceanus/viewArticle.do?id=73766.

Technical Details/Ease of Use

  • Very high-quality images and animations.
