RESEARCH

Human reliance on plummeting fish stocks is predicted to lead to societal and political pressure to cull marine mammals both to increase commercial fish stocks and to utilise marine mammal tissues for human consumption. My research examines the potential repercussions of this by highlighting positive influences of marine mammals on fisheries that may be lost if hunting decimates marine mammal populations.

Specifically, my PhD centres around characterising the ways in which marine mammal transport nutrients within the oceanic water column via three main mechanisms :

1.

vertical transport of water particles during diving

2.

redistribution of nutrients into the photic zone during defecation; and

3.

re-suspension of nutrients during benthic foraging

I am also involved in numerous other projects including investigating the fractal nature of marine mammal diving, continuation of previous research on marine mammal ecotoxicology and examination of dolphin behavioural reactions to construction within the Port River estuary.
