according to NASA as of a few days ago, the above circular
motion has now apparently started to reverse,
indicating a probable cyclical future of several decades of increasing arctic sea
ice.
Cumulative
ice motions for April — July 2008 derived from drift buoys
indicate the overall transport of
ice out of the Beaufort Sea around the Beaufort Gyre to the central Arctic was actually much stronger than in 2007, but it appears to be converging (
motion is slowing) over the Amundsen and Nansen Basins.
