Dedicated Antarctic Blue Whale Project voyages

1. Story
2. Three dedicated Southern Ocean voyages under the IWC-SORP Antarctic Blue Whale Project add 119 photo-identified whales to the Antarctic Blue Whale Catalogue, bringing it to 552 individuals. The catalogue is what makes a capture-recapture abundance estimate possible for a subspecies that is otherwise almost invisible - too few, too dispersed and too far from any coast for conventional survey coverage.

67. 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.
