I am interested in understanding the biogeochemical cycling of bioactive trace metals in the modern ocean. The behavior of these ultra-low concentration metals limits primary growth in vast swaths of the ocean. Since 2012, I have used novel technologies to analyze seawater and marine particles for trace metals in climate sensitive Antarctic shelf systems and the Southern Ocean. Now, I continue to use analytical techniques to investigate the comparative roles of different sources as well as mechanisms that control bioactive trace metals in the water column, and therefore, control ocean productivity in a changing seascape.
