1. Story
2. Photo-identification data collected between the 2003/04 and 2018/19 seasons yields a POPAN superpopulation estimate of 3,506 whales (95% CI 2,107-5,832), with abundance in the final study year estimated at 1,817 (95% CI lower bound 714). The confidence intervals are wide because the sample is small; that width is the honest state of knowledge about the subspecies, not a defect of the method.

40. A POPAN superpopulation estimate from Antarctic blue whale photo-identification collected between 2003/04 and 2018/19 gives 3,506 whales (95% CI 2,107-5,832), with abundance in the final study year, 2018/19, estimated at 1,817 (95% CI lower bound 714); SORP voyages in 2013, 2015 and 2019 added 119 individuals to an Antarctic Blue Whale Catalogue totalling 552. V55 verification basis: these figures were returned in the search result carrying the published abstract text and attributed to this paper.
