Students play a game that demonstrates the importance of primary production by Arctic Ocean ice algae and the use of isotopes to trace sources of nutrients in food webs. They also discuss the implications of shrinking Arctic sea ice as a result of climate change.
Lesson plans, journals, photos, and opportunities to interact with teachers and researchers on a variety of expeditions and cruises to the Arctic and Antarctic.
Near-real time and archived images and data are available from the coastal ice observatories operated by the University of Alaska Fairbanks Geophysical Institutes in the villages of Barrow and Wales, Alaska.
The extent and thickness of Arctic sea ice has diminished significantly during the first decade of the 21rst century, reaching a record low summer extent in 2007. Changes in sea ice have major impacts on Arctic marine ecosystems and on the fish and wildlife species upon which many Alaskan coastal communities and Native cultures depend.
