Seasonal Abundance and Distribution of Cetaceans in a High Traffic Shipping Corridor

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The recovery of many cetacean species coincides spatially and temporally with intensifying anthropogenic threats. We undertook multi‐year systematic surveys to quantify seasonal abundance and document the distribution of at‐risk cetaceans, which is needed to assess the impacts of increasing human activities in the Canadian portions of the ...

Talking About the Weather: The Feasibility of Using Very High‐Resolution Optical Satellite Imagery to Monitor Live and Stranded Cetaceans Around the UK and UK Overseas Territories

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted ...

Hidden Markov Modeling for humpback whale (Megaptera Novaeanglie) call classification

open access: yesProceedings of Meetings on Acoustics, 2012
This study proposes a new approach for the classification of the calls detected in the songs with the use of Hidden Markov Models (HMMs) based on the concept of subunits as building blocks. HMMs have been used once before for such task but in an unsupervised algorithm with promising results, and they are used extensively in speech recognition and in ...

Automatic prosodic clustering of humpback whales song

open access: yes, 2008
6pWe automatically segmented a humpback whale song using the Roger Payne's principle of sound unit and we patterned and automatically classified intonations of sound units thanks to an unsupervised algorithm to describe recurrent patterns.

Source levels of social sounds in migrating humpback whales (Megaptera novaeangliae) [PDF]

open access: yes, 2013
The source level of an animal sound is important in communication, since it affects the distance over which the sound is audible. Several measurements of source levels of whale sounds have been reported, but the accuracy of many is limited because the ...
