Seminar: Francois Primeau – Convergent Estimates of Marine Nitrogen Fixation

Prof. Primeau will present an inverse model to constrain the residual mean circulation of the ocean and to estimate rates of marine nitrogen fixation. The results demonstrate strong spatial variability in the nitrogen to phosphorus ratio of exported organic matter that greatly increases the global nitrogen-fixation rate.

Graeme MacGilchrist. Reframing the carbon cycle of the subpolar Southern Ocean.

Hales Seminar Room Jaeger 7, 142 Mills road, RSES, Acton, ACT, Australia

Graeme MacGilchrist (University of Princeton). Reframing the carbon cycle of the subpolar Southern Ocean. Global climate is critically sensitive to physical and biogeochemical dynamics in the subpolar Southern Ocean, since this is where the deepest, most carbon-rich layers of the world ocean outcrop and exchange carbon with the atmosphere. Here, we show that the conventional... View Article
