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

This experiment provides data and commonuse 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 timeseries traps each along approximately 170E W. In particular, the number of moorings will be concentrated near APF. Additionally, 2 hightension 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.
