Channing Prend is a physical oceanography PhD student at Scripps Institution of Oceanography. He uses observations, satellite data, and climate models to study physical controls on Southern Ocean biogeochemistry. The vPICO presentation uses novel year-round measurements from autonomous biogeochemical floats to show that carbon outgassing occurs predominantly in the Indo-Pacific sector of the Southern Ocean. This zonal asymmetry in carbon outgassing is due to inter-basin variations in the annual mean surface ocean pCO2, which in turn are driven by systematic differences between sectors in the entrainment of carbon-rich deep water into the surface mixed-layer.
