    Research

    Marine Biogeochemistry

    • Using stable N isotopes as tools to decipher the source and sink of nitrogen in the marine environment

    • Spatial and temporal distribution of marine nitrogen fixation and understanding the factors that constrain the distribution and abundance of diazotrophs

    • Understanding the relationship between nitrogen fixation and export production

    • Understanding the biogeochemical impact of cyclonic and anti-cyclonic mesoscale eddies on phytoplankton physiology and community structure in the open ocean

    • Examining the influence of tropical rivers on nutrient biogeochemistry and primary production on the open ocean

    • Determining the distribution and elemental stoichiometry of dissolved organic carbon, nitrogen and phosphorus in the coastal and open ocean
