Specialism: Ocean Chemistry

I am a marine geochemist who works on broad biogeochemical problems through collaboration with interdisciplinary teams. My work involves both ship based fieldwork and laboratory based analyses and experiments.

Over the course of my career I have made significant contributions to the understanding of active hydrothermal deposit formation and alteration. I currently work closely with biologists and microbiologists to understand the interactions between microbial and macrobiotic communities and seafloor mineral deposits. A particular focus is on the biological impact on diagenetic processes and chemical fluxes within and around active and inactive hydrothermal systems.

More recently we have used hydrothermal sediment geochemistry to infer past Pacific ocean ventilation over the late Pleistocene, quantify low-temperature hydrothermal circulation through young ocean crust and to estimate the impact of microbial processes on mineralisation at the seafloor. We have used a range of proxies of sedimentary processes to evaluate carbon sequestration into the deep ocean in an area of natural iron fertilisation in the Southern Ocean. We use sediment geochemistry to test the validity of newer proxies and to quantify boundary fluxes of trace metals in the South Atlantic.

My most recent developments include collaboration with biological chemists to evaluate the response of diatom metabolism to nutrient limitation and to develop a range of new lipid-based proxies for environmental parameters.
