CryoSat extends its reach on the Arctic
15 December 2014
CryoSat has delivered this year's map of autumn sea-ice thickness in the Arctic, revealing a small decrease in ice volume. In a new phase for ESA's ice mission, the measurements can now also be used to help vessels navigate through the north coastal waters of Alaska, for example.
Measurements made during October and November show that the volume of Arctic sea ice now stands at about 10,200 cubic km - a small drop compared to last year's 10,900 cubic km.
The volume is the second-highest since measurements began in 2010, and the five-year average is relatively stable. This, however, does not necessarily indicate a turn in the long-term downward trend.
