Stephanie Dutkiewicz

Research Interests:
Dr. Dutkiewicz works on elucidating the role of biological activity on the distribution of carbon within the oceans. Her current research aims to improve the representation of air-sea interactions and biogeochemical cycling in the MIT ocean general circulation model (GCM). She is involved in collaborative projects with the MIT Climate Modeling Initiative and The Darwin Project, among others. Her research centers on the cycling of carbon by both the "solubility pump" and "biological pump" in the 3D ocean models. She models the movement of the surface water through sinking and advection that redistributes the carbon concentrations in the ocean, and where biological activity fluxes carbon from the surface waters to the deep ocean.
