Research Spotlight: Airborne study reveals Arctic sea ice thickness


  • Ernie Tretkoff


Arctic sea ice extent has declined over the past several decades and in 2007 reached a record-breaking low. Since then, ice has begun to recover. Sea ice thinning is expected to continue with climate change, although there is significant natural variability in ice extent and thickness. To understand the effects of climate change on sea ice and to make forecasts, scientists need reliable sea ice thickness data, but Arctic sea ice thickness information is scarce.
