Humpback Whale’s Flukes Segmentation Algorithms
2021Photo-identification consists of the analysis of photographs to identify cetacean individuals based on unique characteristics that each specimen of the same species exhibits. The use of this tool allows us to carry out studies about the size of its population and migratory routes by comparing catalogues. However, the number of images that make up these

Humpback whale song: who sings?
Behavioral Ecology and Sociobiology, 2013While on their winter breeding grounds, male humpback whales (Megaptera novaeangliae) produce long sequences of structured vocalizations called song, whose function within the mating system is still unresolved. Here we ask which males sing. Is it only those sexually mature, as typifies songbirds and some lekking ungulates in which vocalizations during ...

Cetacean morbillivirus in Humpback whales’ exhaled breath
Transboundary and Emerging Diseases, 2020The humpback whale (HW; Megaptera novaeangliae) population that seasonally resides along the Brazilian coast concentrates in the Abrolhos Bank (Bahia and Espírito Santo states) for breeding during austral winter and spring. Cetacean morbillivirus (CeMV, Paramyxoviridae family) is currently one of the most significant biological threats to cetaceans ...

1) Humpback whales (Megaptera novaeangliae) produce a series of beautiful and varied sounds for a period of 7 to 30 minutes and then repeat the same series with considerable precision. We call such a performance "singing" and each repeated series of sounds a "song." 2) All prolonged sound patterns (recorded so far) of this species are in song form, and

Hydrodynamic design of the humpback whale flipper
Journal of Morphology, 1995AbstractThe humpback whale (Megaptera novaeangliae) is reported to use its elongate pectoral flippers during swimming maneuvers. The morphology of the flipper from a 9.02‐m whale was evaluated with regard to this hydrodynamic function. The flipper had a wing‐like, high aspect ratio plan‐form.

The Humpback Whale Acoustic Research Collaboration studies on the use of sound by humpback whales
The Journal of the Acoustical Society of America, 2006Humpback whales produce two different types of vocalizations with apparent difference functions: songs and social sounds. There is also the potential to use the sounds of their environment, such as surf noise during migration along coasts, though this has not been demonstrated.

Historical Studies in the Natural Sciences
The release of Songs of the Humpback Whale in 1970 helped galvanize a torrent of North American activism to save the whale from commercial whaling. Whale song quickly became a cornerstone of environmentalist and New Age political culture. This article places humpback whale song science in the larger context of acoustic science and technology, arguing ...

Recording Whale Watching Tour and Humpback Whale Collisions
2023The purpose of this research protocol is to record collisions caused by whale watching boat tours. We make use of remotely operated water vehicles to collect video footage of whale watching tours and analyze the footage simultaneously. This data will be taken over a five year period at multiple whale watching sites along the coast of Mo'orea, French ...
