"Latitudinal Variations of Particle Fluxes at the Southern Ocean: A Bottom Tethered Sediment Trap Array Experiment"

This experiment provides data and common use samples on how the biological pump operates in the Southern Ocean and how it could potentially impact the level of atmospheric CO₂. We deploy 5 deep moorings with 3 or 4 time series traps each along approximately 170W. In particular, the number of moorings will be concentrated near APF. Additionally, 2 high tension moorings in the Ross Sea will be deployed. The temporal resolution of this experiment is 17 or 8.5 days. We provide the total export fluxes, fluxes of org. C, N, bio/litho SiO₂ and CaCO₃ as the core data.
