Arctic sea ice is in constant motion, riding on the ocean and absorbing energy from circumpolar weather systems. These dynamics may have an effect the thickness and durability of the arctic ice pack in the face of climate change. University of Alaska Fairbanks researcher Jennifer Hutchings is chief scientist on an expedition that will spend two weeks at studying these complex relationships at an ice camp on the Beaufort Sea.
