Abstract
Biophysical features modulate pelagic environments by increasing the productivity of nutrient-poor regions, yet their influence on sharks is poorly understood. In this thesis, I use interdisciplinary techniques including satellite telemetry, acoustics, and oceanographic observations, and statistical modelling to quantify the pelagic prey field and physical structure of the water column in the vicinity of tagged sharks to examine how these features influence sharks in Western Australia. I found that despite contrasting foraging guilds and live histories, biophysical features that had the greatest effects on shark movement and behaviour were those that improved prey encounter rates and foraging efficiency.
