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 Despite their enormous size, whales make living as voracious predators. To catch much smaller, more maneuverable prey, they have developed several unique locomotor strategies that require high energetic input, mechanical power output and a surprising degree of agility. better understand how body size affects maneuverability at the largest scale, we used bio-logging data, aerial photogrammetry high-throughput approach to quantify maneuvering performance seven species free-swimming...
Humpback whales (Megaptera novaeangliae) have exceptionally long pectorals (i.e. flippers) that aid in shallow water navigation, rapid acceleration and increased manoeuvrability. The use of to herd or manipulate prey has been hypothesized since the 1930s. We combined new technology a unique viewing platform document additional aggregate during foraging events. Here, we provide description 'pectoral herding' explore conditions may promote this innovative behaviour. Specifically, analysed...
In the field, tidepool sculpin, Oligocottus maculosus, has been observed to display a vertical intertidal distribution characterized by increasing mean standard length with decreasing distance above tidal height. It was hypothesized that this is related intercohort competition for food and (or) cover and, as result, competi tive exclusion of smaller fish larger from lower pools. To test hypothesis, several experiments were conducted involved pairing O. maculosus three size classes in...
This study investigates the use of a mobile application, Whale mAPP, as citizen science tool for collecting marine mammal sighting data. In just over three months, 1261 sightings were observed and recorded by 39 scientists in Southeast Alaska. The resulting data, along with preliminary post-Whale mAPP questionnaires, used to evaluate tool’s scientific, educational, engagement feasibility. A comparison Steller sea lion distribution data scientific dataset comparable (91% overlap) given high...
Abstract Humpbacks whales ( Megaptera novaeangliae ) have shown a remarkable recovery in the North Pacific, raising concerns regarding their impact on marine communities. In Southeast Alaska, humpbacks feed heavily euphausiids; however, it remains unclear whether they target immature individuals despite evidence that do so elsewhere. I evaluate hypothesis euphausiids late spring‐summer Alaska. Plankton samples were collected at random sites n = 44) and near 53) between 8 June 9 September...
Across their range humpback whales (Megaptera novaeangliae) produce a wide array of vocalizations including song, foraging vocalizations, and variety non-song known as social calls. This study investigates the calling behavior Southeast Alaskan from sample 299 paired with 365 visual surveys collected over three-month period on ground in Frederick Sound Alaska. Vocalizations were classified using visual-aural analysis, statistical cluster analyses, discriminant function analysis. The...
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...
