The Southern Hemisphere Blue Whale Catalogue has a total of 1,773 individual blue whale photoidentifications (photo-IDs) that include regions off Antarctica, Chile, Peru, Ecuador-Galapagos, Eastern Tropical Pacific (ETP), Australia, Timor-Leste, New Zealand, southern Africa, Madagascar and Sri Lanka. From May 2019 to April 2020, photo comparisons from within the Australia-NewZealand-Indonesia region
have been completed and photo comparisons between catalogues from Southeast Pacific and ETP region were started. A considerable amount of new photo-identifications (+188 IDs) have been received representing an increase of 12% of blue whale identifications over one year. Photo-quality and data control will be conducted to matched whale IDs prior to starting work on abundance estimates.
