Arctic sea ice extent (spatial coverage) this fall is still tied with 2007 as the lowest on record (upper left) and the extent anomalies (values compared with the 1979-2000 mean) continue to decline (upper right): Minimum sea ice area is also down again this year (lower right) and Arctic ice volume is at a record low this year and the September 2011 value was also a record low (go here for more info).
