|My research interests lie in the structure and driving forces behind polar and deep sea communities. For the most part I’ve focused on food webs; examining stomach contents of fish to identify patterns of omnivory, ontogenetic and size based shifts in diet and resource partitioning. I’m now moving into the field of stable isotope analysis as an alternative technique to understanding some of these processes.|
Macro-consumer food web structure of mid-ocean ridges: The fate of chemosynthetic and photosynthetic energy input at contrasting sites in the North Atlantic and Southern Oceans.
I am currently undertaking a PhD using stable isotopes of carbon, nitrogen and sulphur to investigate trophodynamics in various deep sea habitats funded by the Natural Environmental Research Council (NERC). The study areas span the entire Atlantic from the Charlie Gibbs Fracture Zone on the Mid-Atlantic Ridge, along with seamounts and continental slopes in the northern hemisphere to chemosynthetic environments on the Scotia Arc in the Southern Ocean. The aims of the work are to examine how different energy sources affect the trophodynamics of each of these habitats, to see whether these systems show signs of trophic size structuring and if there are habitat/ spatial differences in trophic size structuring at both species and community levels.
The PhD is part of two NERC funded consortium projects: Ecosystems of the Mid-Atlantic Ridge at the Sub-Polar Front and Charlie-Gibbs Fracture Zone (ECOMAR) and Chemosynthetically driven ecosystems south of the Polar Front (ChEsSo). The study sites for these projects are on the Mid-Atlantic Ridge (MAR), in the North Atlantic Ocean, and East Scotia Ridge (ESR), in the Atlantic sector of the Southern Ocean. The biological communities at the two study sites are driven by two different sources of energy; photosynthetic energy via bentho-pelagic coupling on the MAR and chemosynthetic energy. I have also received funding from the Census of Marine Life on Seamounts (CenSeam) to undertake further research on the deep water fish communities of the Rockall Trough and Rosemary Seamount, in collaboration with Fisheries Research Services.
