Multidisciplinary,
multi-platform
controlled experiments

• Visual and acoustic tracking
• Behavioural observations
• DTAGs – 3D motion
• Acoustic recordings
• Biopsies DNA, hormones
• Complete characterisation        • Two major experiments off
   of the acoustic environment            Queensland:
• Photo IDs                        • > 400 singers tracked acoustically
• Playback
                                   • > 2000 whales tracked visually

                                    to approaching powerboats
