Professor Bradley Eyre
I am a biogeochemist with diverse research interests, but mostly focused on the flow of carbon and nitrogen through coastal ecosystems. I uses a variety of research approaches in my work, on scales from a few meters to global estimates, including in-situ process measurements, natural abundance, tracer and compound specific stable isotopes measurements, experimental manipulations, ecosystem comparisons, ecosystem stimulation modeling and material mass-balances. Much of my work has been in (sub) tropical coastal systems, but he has also worked in warm and cold temperate and arctic systems.
My publications include topics such as whole ecosystem carbon, nitrogen and phosphorus budgets, net ecosystem metabolism estimates, benthic and pelagic production and respiration, dissolved organic carbon fluxes, carbon stable isotopes (fluxes and assimilation), carbon burial and air-sea CO2 flux estimates, benthic denitrification, benthic habitats and seascapes, historical and ecosystem comparisons, ocean acidification, hypoxia, eutrophication, submarine groundwater discharge and permeable sands.
