Changing Planet: Fresh Water in the Arctic
http://www.nbclearn.com/changingplanet/cuecard/52043

NBC Learn, NESTA - Windows to the Universe

This Changing Planet video documents scientists' concerns regarding how melting Arctic sea ice will increase the amount of fresh water in the Beaufort Gyre, which could spill out into the Atlantic and cause major climate shifts in North America and Western Europe. The video includes interviews with scientists and a look at the basics of how scientists measure salinity in the ocean and how ocean circulation works in the Arctic.

Video length 5:18 min.

Teaching Tips

About the Science

  • This video examines the impacts of fresh water flowing into the Arctic Ocean from ice and rivers on thermohaline circulation using advanced, specifically-designed engineering.
  • Scientists profiled are from Woods Hole Oceanographic Institute and other research institutes.
  • Good background information and references given in the accompanying lesson plan: http://www.windows2universe.org/teacher_resources/leaky_gyre.html.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • The video outlines the issues of fresh water flowing into the Arctic Sea and the challenges that scientists face collecting data there.
  • Teachers should be aware (and pass on to students) that climate change will have different impacts in different parts of the world and that it won't be "warming" everywhere.

Technical Details/Ease of Use

  • Video quality is not ideal; video may be pixelated at larger viewing sizes.
