Dr Pearse Buchanan

Postdoctoral researcher, University of Liverpool

My research focuses on the mechanisms that control ocean biogeochemical cycles, particularly involving the interactions between plankton and their physical environment.

I am particularly interested in using stable isotopes of nitrogen and carbon to understand these biogeochemical interactions at a deeper level.

I came to the University of Liverpool to work with Alessandro Tagliabue and Claire Mahaffey on the Arctic Isotopes and Seals (ARISE) project. My role is to provide a model-based perspective on how the base of Arctic food webs might respond to a warming climate, which will supplement ongoing analyses of how seals, the top of the Arctic food web, are responding.

By using independent methods to understand changes in the base and top of Arctic food webs, we hope to detect how Arctic food webs are responding to rapid warming.
