The Southern Ocean, which represents 30% of the global ocean surface area, accounts for about 40% of total ocean uptake of anthropogenic carbon dioxide (CO2) by both the solubility and biological carbon pumps (Frölicher et al., 2015; Landschützer et al., 2015; Sabine et al., 2004). Quantifying annual net community production and particle flux attenuation in the Southern Ocean is important for understanding the roles of the Southern Ocean in carbon uptake and climate. Only a few studies have attempted this, mostly at individual sites based on measurements from ships or moorings. Expanding from this local, regional or process-study scale to the basin scale requires extension from traditional sampling techniques like ships and moorings to satellites without depth dimension and then towards a greater use of autonomous platforms and sensors such as Biogeochemical-Argo (BGC-Argo) floats (Johnson et al., 2017). This increased understanding from new observations can then feed into development of improved models ...
