A classic case in point was the discovery that field observations of the loss of arctic sea ice showed that by 2007 it had advanced to a level predicted by the mean of models of that loss as occurring in the 2100s, while that mean was used as the consensus projection in AR4.

Field observations summarized in the contribution by Hutchings and discussed in this month's Regional Outlook indicate that starting ice thicknesses were comparable to last year in the Beaufort and Chukchi Seas, and that after getting off to a fast start, melt has slowed down considerably, resulting in below - normal melt rates.

Community - based observations and field data for the Bering Sea ice cover summarized in the Sea Ice for Walrus Outlook (SIWO) indicate that even though Bering Sea ice was extensive, it was thinner than in past decades and hence susceptible to rapid retreice cover summarized in the Sea Ice for Walrus Outlook (SIWO) indicate that even though Bering Sea ice was extensive, it was thinner than in past decades and hence susceptible to rapid retreIce for Walrus Outlook (SIWO) indicate that even though Bering Sea ice was extensive, it was thinner than in past decades and hence susceptible to rapid retreice was extensive, it was thinner than in past decades and hence susceptible to rapid retreat.

Field observations and a drifting buoy tracking through the region also reveal that widespread refreezing of surface ice meltwater as it comes into contact with colder, more saline seawater, has added ice layers to the bottom of floes, slowing down thinning and melt of the ice cover.
