New estimates of Southern Ocean annual net community production revealed by BGC-Argo floats
Using an expanding Southern Ocean fleet of biogeochemical Argo (BGC-Argo) floats, we developed a novel approach to estimate annual net community production (ANCP) by integrating subsurface oxygen drawdown from all available BGC-Argo oxygen profiles. Our results suggest that, on average, 14% of remin...
