Specialist Subjects: The ecophysiology of plankton (phytoplankton, zooplankton, bacteria and viruses), both from an experimental view point and for the construction and use of mechanistic models describing their behaviour and trophic interactions. Keywords: plankton, stoichiometry, marine biogeochemistry, climate models
Current research is centred on the development of mechanistic models describing multi-nutrient interactions between plankton functional groups. Although models describing these groups (e.g. diatoms, microzooplankton) are included within climate change and regional seas models, where they play a dominant role in driving the biogeochemistry, these models are in the main very simplistic and incapable of describing the processes adequately. Models have been, and are being developed to better describe the activities of these organisms, associated with appropriate experimental studies.
