Canadian Ice Service, 3.8, Heuristic Arctic Ocean September sea ice extents (while expected to be well below the 1979 ‐ 2013 average of 6.4 million square kilometres, and while expected to continue to be near or below 4.0 million square kilometres) are therefore expected to experience a slight recovery, preventing a repeat of last year's record.
