NASA Satellite Survey Reveals Dramatic Arctic Sea Ice Thinning measurements of winter sea ice thickness over Arctic Ocean, 2004 and 2008
A new research paper published by the NASA Jet Propulsion Laboratory shows that arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.
