Abstract : Behavioral response studies (BRS) are increasingly being conducted to better understand basic behavioral patterns in marine animals and how underwater sounds, including from human sources, can affect them. These studies are being enabled and enhanced by advances in both acoustic sensing and transmission technologies. In the design of a 5-year project in southern California (SOCAL-BRS) the development of a compact, hand-deployable, ship-powered, 15-element vertical line array sound… Expand

An animal-borne active acoustic tag for minimally invasive behavioral response studies on marine mammals
TLDR
The ability of an animal-mounted sound source to elicit behavioral responses in free-ranging individuals is demonstrated, and Responses did not consistently differ based on stimulus type, which may be attributable to the unique exposure context of the very close proximity of the sound source. Expand
A systematic review on the behavioural responses of wild marine mammals to noise: the disparity between science and policy
TLDR
The analysis emphasized that behavioural responses in cetaceans (measured via a linear severity scale) were best explained by the interaction between sound source type (continuous, sonar, or seismic/explosion) and functional hearing group (a proxy for hearing capabilities). Expand
Prey-mediated behavioral responses of feeding blue whales in controlled sound exposure experiments.
TLDR
The integrated approach demonstrated that deep-feeding whales respond more clearly and strongly to CEEs than those in other behavioral states, but this was only evident with the increased explanatory power provided by incorporating prey density and distribution as contextual covariates. Expand
Sonar inter-ping noise field characterization during cetacean behavioral response studies off Southern California
The potential negative effects of sound, particularly active sonar, on marine mammals has received considerable attention in the past decade. Numerous behavioral response studies are ongoing aroundExpand
Behavioral responses of individual blue whales (Balaenoptera musculus) to mid-frequency military sonar
TLDR
Overall, responses were generally brief, of low to moderate severity, and highly dependent on exposure context such as behavioral state, source-to-whale horizontal range and prey availability, which depended on contextual factors. Expand
Behavioral and Physiological Response of Baleen Whales to Ships and Ship Noise
Abstract : We began this study in 2013 with goal of examining the behavioral and physiological response of blue whales to ships and ship noise off California using a combination of opportunistic andExpand
Novel Bio-Logging Tool for Studying Fine-Scale Behaviors of Marine Turtles in Response to Sound
Increases in the spatial scale and intensity of activities that produce marine anthropogenic sound highlight the importance of understanding the impacts and effects of sound on threatened speciesExpand
A Case Study of a Near Vessel Strike of a Blue Whale: Perceptual Cues and Fine-Scale Aspects of Behavioral Avoidance
Despite efforts to aid recovery, Eastern North Pacific blue whales faces numerous anthropogenic threats. These include behavioral disturbances and noise interference with communication, but alsoExpand
Blue whales respond to simulated mid-frequency military sonar
TLDR
It is demonstrated that mid-frequency sound can significantly affect blue whale behaviour, especially during deep feeding modes, and sonar-induced disruption of feeding and displacement from high-quality prey patches could have significant and previously undocumented impacts on baleen whale foraging ecology, individual fitness and population health.

Nowhere to go: noise impact assessments for marine mammal populations with high site fidelity
As awareness of the effects of anthropogenic noise on marine mammals has grown, research has broadened from evaluating physiological responses, including injury and mortality, to considering effectsExpand

Acoustic playback experiments to study behavioral responses of free-ranging marine animals to anthropogenic sound
TLDR
The pre- sent paper argues for a balance of experimental and observational studies of effects of sound on marine life, designed so that each kind of study complements the other. Expand
Studying the behaviour and sensory ecology of marine mammals using acoustic recording tags: a review
TLDR
The application of acoustic tags to studies of vocal behaviour, foraging ecology, acoustic tracking, and the effects of noise is examined to assess both the breadth of applications and the specific issues that arise in each. Expand
Acoustic masking in marine ecosystems: intuitions, analysis, and implication
TLDR
An analytical paradigm to quantify changes in an animal's acoustic communication space as a result of spatial, spectral, and temporal changes in background noise is presented, providing a functional defini- tion of communication masking for free-ranging animals and a metric to quantify the potential for communicationmasking.

Estimating cetacean population density using fixed passive acoustic sensors: an example with Blainville's beaked whales.
TLDR
Methods are developed for estimating the size/density of cetacean populations using data from a set of fixed passive acoustic sensors, potentially applicable to a wide variety of marine and terrestrial species that are hard to survey using conventional visual methods. Expand

Beaked Whales Respond to Simulated and Actual Navy Sonar
TLDR
It is shown that in both exposure conditions beaked whales stopped echolocating during deep foraging dives and moved away, indicating similar disruption of foraging behavior and avoidance by beaked whale in the two different contexts, at exposures well below those used by regulators to define disturbance.

TLDR
Gas-bubble disease, induced in supersaturated tissue by a behavioural response to acoustic exposure, is a plausible pathologic mechanism for the mortality andbidity seen in cetaceans associated with sonar exposure and merits further investigation. Expand
