Hybrid framework for categorising sounds of Mysticete whales
IET Signal Processing, 2017 This study addresses a problem belonging to the domain of whale audio processing, more specifically the automatic classification of sounds produced by the Mysticete species. The specific task is quite challenging given the vast repertoire of the involved species, the adverse acoustic conditions and the nearly inexistent prior ...

Mysticete migration revisited: are Mediterranean fin whales an anomaly?
Mammal Review, 2016Abstract The generally accepted model of Mysticete whale migration is that most individuals undertake seasonal migrations between high and low latitudes. Although numerous exceptions have been described in the literature, the traditional model remains unexamined.

How do Mysticete (Baleen) Whales Make Two Sounds Simultaneously?
The FASEB Journal, 2019 Mysticete (baleen) whales use the larynx to generate sounds. Air flowing past the U‐shaped vocal folds causes vibrations that are transferred through overlying throat tissues to water. Sounds can be made repetitively without surfacing for a breath due to

Mitochondrial Phylogenetics and Evolution of Mysticete Whales [PDF]
Systematic Biology, 2005 The phylogenetic relationships among baleen whales (Order: Cetacea) remain uncertain despite extensive research in cetacean molecular phylogenetics and a potential morphological sample size of over 2 million animals harvested. Questions remain regarding the number of species and the monophyly of genera, as well as higher order relationships.

Total neocortical cell number in the mysticete brain [PDF]
Anatomical Record, 2007 AbstractThe cetacean brain has long been of scientific interest, not only because of its large size – the largest in the animal kingdom – but also because of its high gyrification. It shows several adaptations to the aquatic environment, especially in the cortical arrangements of functional areas.

Methods for automatic detection of mysticete sounds
Marine and Freshwater Behaviour and Physiology, 1997Methods for the automatic recognition of low‐frequency sounds of baleen whales are presented. Matched filtering is implemented with a synthetic filter kernel derived from measurements of whale sounds, and this method is found effective at detecting blue whale (Balaenoptera musculus) sounds in white background noise.

Classification of mysticete sounds using machine learning techniques
Journal of the Acoustical Society of America, 2013Automatic classification of mysticete sounds has long been a challenging task in the bioacoustics field. The unknown statistical properties of the signals as well as the use of different recording apparatus and low signal-to-noise ratio conditions often lead to non-optimal systems.
