For the 40 years after end of commercial whaling in 1976, humpback whale populations North Pacific Ocean exhibited a prolonged period recovery. Using mark–recapture methods on largest individual photo-identification dataset ever assembled for cetacean, we estimated annual ocean-basin-wide abundance species from 2002 through 2021. Trends estimates describe strong post-whaling era population recovery 16 875 (± 5955) to peak estimate 33 488 4455) 2012. An apparent 20% decline 2012 2021, 26 662...
We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for most living individual humpback whales (Megaptera novaeangliae) in the North Pacific Ocean. The was built through a broad collaboration combining 39 separate curated photo-ID catalogs, supplemented with community science data. Data from throughout were aggregated into 13 regions, including six breeding feeding one migratory corridor. All images compared minimal...

Abstract Rough‐toothed dolphins ( Steno bredanensis ) typically inhabit deep oceanic waters from tropical to temperate worldwide. However, their ecology and behavior remain poorly understood. We investigated site fidelity social structure of rough‐toothed using photo‐identification data collected between 2014 2022 in the continental shelf southwestern coast Mexico. A total 133 groups were recorded. Mean group size was 4.9 individuals SD = 4.5), encountered a mean depth 110 m 188). Of 228...
Abstract We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for the majority of living individual humpback whales ( Megaptera novaeangliae ) in North Pacific Ocean. The was built through a broad collaboration combining 39 separate curated photo-ID catalogs supplemented with community science data. All available images were compared using recently developed machine learning artificial intelligence image recognition...
