Microbial Ecology and Biogeochemistry in the Anthropocene Sea

There are half a billion microorganisms in a glass of seawater, and we have no idea what many of these organisms ‘do’ – for example, what they ‘eat,’ how they survive, or how they interact.  We do know that the collective activities of these tiny cells drive global cycles of biologically-essential elements such as nitrogen and carbon, while global biogeochemical cycles have subsequently been heavily altered by human activities.  The overarching goal of our research is to develop an integrative and predictive understanding of microbial ecology and biogeochemical cycling in rapidly changing aquatic ecosystems, especially the ‘Anthropocene Sea.’
