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 ...
Blue whales respond to simulated mid-frequency military sonar
(2013) - Journal article,
Mid-frequency military (1–10 kHz) sonars have been associated with lethal mass strandings of deep-diving toothed whales, but the effects on endangered baleen whale species are virtually unknown. Here, we used controlled ...
Whistle characteristics and daytime dive behavior in pantropical spotted dolphins (Stenella attenuata) in Hawai‘i measured using digital acoustic recording tags (DTAGs)
(2016-07-19) - Journal article,
This study characterizes daytime acoustic and dive behavior of pantropical spotted dolphins (Stenella attenuata) in Hawai‘i using 14.58 h of data collected from five deployments of digital acoustic recording tags (DTAG3) ...
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 ...
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.
Naval sonar disrupts foraging behaviour in humpback whales
(2016-12-29) - Journal article,
Modern long-range naval sonars are a potential disturbance for marine mammals and can cause disruption of feeding in cetaceans. We examined the lunge-feeding behaviour of humpback whales Megaptera novaeangliae before, ...

Acoustic playback experiments to study behavioral responses of free-ranging marine animals to anthropogenic sound
(2009-12-03) - Journal article,
Growing concern about the effects of anthropogenic sound on marine life has highlighted the need for empirical methods to study behavioral responses of marine animals to specific acoustic exposures. Some effects have been ...
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, ...
Short first click intervals in echolocation trains of three species of deep diving odontocetes
(2017-02) - Journal article,
All odontocetes produce echolocation clicks as part of their vocal repertoire. In this paper we analysed inter-click-intervals in recordings from suction cup tags with a focus on the first inter-click interval of each click ...
