Final circumpolar estimates from the International Whaling Commission (IWC) IDCR/SOWER population surveys (1978/79-2003/04) were 338,000 — only 39% of the 1985/86-1990/91 surveys.[12] As of January, 2010, The IWC states it is "unable to provide reliable estimates at the present time" and that a "major review is underway by the Scientific Committee."[13]
As of 2008, one estimate submitted to the IWC Scientific Committee by the Japanese government researchers suggested that for Southern Hemisphere (CPIII with common Northern Boundaries) is 665,074.[14] In the early 1990s, the IWC Scientific Committee agreed minkes in the Southern Hemisphere numbered 760,000 (CPII), which the Japanese whaling industry currently uses as the (2005) estimate.[citation needed] In 2000, however, the Committee withdrew this advice in light of new survey data suggesting 50% lower population than in the 1980s.[15]
