Getting below the surface : density estimation methods for deep diving animals using slow autonomous underwater vehicles
(University of St Andrews, 2018) - Thesis
Underwater gliders can provide an alternative cost-effective platform for passive acoustic monitoring surveys, compared to boat surveys, for abundance estimation and to collect high resolution environmental data for habitat ...
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), ...
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) ...
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, ...
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.
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 ...
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 ...
