Predator sound playbacks reveal strong avoidance responses in a fight strategist baleen whale
(2015)
Anti-predator strategies are often defined as ‘flight’ or ‘fight’, based upon prey anatomical adaptations for size, morphology and weapons, as well as observed behaviours in the presence of predators. The humpback whale ...
Biological significance of sperm whale responses to sonar: Comparison with anti-predator responses
(2016)
A key issue when investigating effects of anthropogenic noise on cetacean behavior is to identify the biological significance of the responses. Predator presence can be considered a natural high-level disturbance stimulus ...
Severity Scoring of Behavioral Responses of Sperm Whales (Physeter macrocephalus) to Novel Continuous versus Conven tional Pulsed Active Sonar
(2021-04-19)
Controlled exposure experiments (CEEs) have demonstrated that naval pulsed active sonar (PAS) can induce costly behavioral responses in cetaceans similar to antipredator responses. New generation continuous active sonars ...
The 3S3 experiment data report - using operational naval sonars to study the effects of continuous active sonar, and source proximity, on sperm whales
(2021-03-18)
The 3S project is an international collaborative effort with the aim to investigate behavioral
reactions of cetaceans to naval sonar signals. The objectives of the third phase of the project
(3S3) were to investigate if ...
Modeling potential masking of echolocating sperm whales exposed to continuous 1-2 kHz naval sonar
(2021-04-30)
Modern active sonar systems can (almost) continuously transmit and receive sound, which can lead to more masking of important sounds for marine mammals than conventional pulsed sonar systems transmitting at a much lower ...
