A 3D stereo camera system for precisely positioning animals in space and time
(2015-04) - Journal article,
Here, we describe a portable stereo camera system that integrates a GPS receiver, an attitude sensor and 3D stereo photogrammetry to rapidly estimate the position of multiple animals in space and time. We demonstrate the ...
Trackline and point detection probabilities for acoustic surveys of Cuvier’s and Blainville’s beaked whales
(2013-02) - Journal article,
Acoustic survey methods can be used to estimate density and abundance using sounds produced by cetaceans and detected using hydrophones if the probability of detection can be estimated. For passive acoustic surveys, ...

Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015-11-20) - Journal article,
Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ...
Echolocation : clicking for supper
(2015-04-29) - Journal article,
When close to prey, porpoises actively widen their sonar beam, which may make it harder for the prey to escape.
Sound production and associated behavior of tagged fin whales (Balaenoptera physalus) in the Southern California Bight
(2015-08-03) - Journal article,
Background: For marine animals, acoustic communication is critical for many life functions, yet individual calling behavior is poorly understood for most large whale species. These topics are important for understanding ...
Changes in dive behaviour during naval sonar exposure in killer whales, long-finned pilot whales, and sperm whales.
(2012-10-11) - Journal article,
Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), ...
The challenges of analyzing behavioral response study data : an overview of the MOCHA (Multi-study OCean acoustics Human effects Analysis) project
(Springer Science and Business Media, 2016) - Conference item,
This paper describes the MOCHA project which aims to develop novel approaches for the analysis of data collected during Behavioral Response Studies (BRSs). BRSs are experiments aimed at directly quantifying the effects of ...
Vocal Learning and Auditory-Vocal Feedback
(Springer, 2016) - Book item,
Vocal learning is usually studied in songbirds and humans, species that can form auditory templates by listening to acoustic models and then learn to vocalize to match the template. Most other species are thought to develop ...
Estimated tissue and blood N2 levels and risk of in vivo bubble formation in deep-, intermediate- and shallow diving toothed whales during exposure to naval sonar.
(2012-05-10) - Journal article,
Naval sonar has been accused of causing whale stranding by a mechanism which increases formation of tissue N2 gas bubbles. Increased tissue and blood N2 levels, and thereby increased risk of decompression sickness (DCS), ...
