Biography

My current research interests include: understanding predator-prey interactions in the Southern Ocean, focussing on penguins, seals, krill and fish; and marine debris and conservation including an assessment of marine mammal entanglements and the response of penguins to helicopter disturbance. I am interested in developing new methodologies for monitoring predator populations for example using remote sensing to assess penguin distribution and abundance, and using prey DNA to assess predator diets.

 

Much of my work involves the analysis of data collected as part of the biological sciences Long Term Monitoring and Survey programme (LTMS), which, since the early 1980s, has recorded annual data on breeding, foraging and diet parameters for bird and seal populations in the Scotia Sea, along with ship-based surveys of krill abundance. Using these data we can examine patterns and changes in the Southern Ocean ecosystem over the last three decades, and analyse spatial and temporal variability in food web dynamics.

 

My research contributes to the development of ecosystem based approaches to fisheries management in the Antarctic through the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

 

My previous projects include quantifying Squid from Space (using remotely sensed data on fishing lights to examine the distribution of fished populations in the South Atlantic and South Pacific oceans), and an investigation of the influence of local and large scale oceanography, including the El Niño-Southern Oscillation (ENSO), on squid populations in the southern hemisphere.
