I am currently collaborating with MBARI Scientist Andrea Fassbender to use profiling floats equipped with O2, NO3–, bio-optical, and pH sensors to make budgets of biogeochemical tracers of carbon export in the Northeast Pacific. This NSF-funded project is in collaboration with, and will provide regional and historic hydrographic context for in-situ, ship-based, and satellite-based export assessments made during the NASA EXPORTS study. One goal of the project is to evaluate the evolution of surface ocean carbon export in distinct biogenic carbon pools over multiple timescales, which will contribute to improved future satellite-based export models.
My research interests include: 1) Marine biological production and carbon export, 2) Upper ocean physicochemical dynamics, 3) Global biogeochemical cycling of C, O, and N, 4) Coastal ocean processes, 5) Stable and radioisotope tracers, and 6) Autonomous sampling platforms.
