I seek a fundamental understanding of the interdependence between ecological diversity and biogeochemical fluxes in the ocean. In the upper euphotic zone, carbon, nitrogen and phosphorus move rapidly between particulate organic matter, dissolved organic matter and their inorganic forms. Alongside this fast cycle is a slow one. The export of sinking organic particles is balanced by the upwelling of inorganic nutrients from the deep sea. How are these two cycles coupled? Does ecology drive export or does upwelling set the ecology? Any attempt to answer these questions is muddled by the extreme diversity inside each nutrient reservoir. Dissolved organic material contains tens of thousands of unique compounds, and free living plankton include tens of thousands of species that interact differently with their chemical environment and one another. I look for ways to simplify these interactions.
