NOAA ClimateWatch Magazine: Loss of multi-year Arctic sea ice, 1987-present
Entry ID: NOAA-CWM_LossMulti-YearArctic1987-Present

[ Update this Record ]

Abstract: Animation of maps of sea ice age classification from 1987 through mid-August 2012. The first age class on the scale (1) means “first-year ice,” which is ice that formed in the most recent winter. The oldest ice (>9) is ice that is more than 9 years old. Dark gray areas indicate open water or else coastal regions where the spatial resolution of the data is coarser than the land map.

(Animation by team, based on research data provided by Mark Tschudi, CCAR, University of Colorado.)
