Interannual drivers of the seasonal cycle of CO2 in the Southern Ocean

Luke Gregor et al.

Data sets

Dataset for empirically estimated pCO2 for the Southern Ocean: RFR and SVR L. Gregor, P. M. S. Monteiro, S. Kok

Short summary
The Southern Ocean accounts for a large portion of the variability in oceanic CO2 uptake. However, the drivers of these changes are not understood due to a lack of observations. In this study, we used an ensemble of gap-filling methods to estimate surface CO2. We found that winter was a more important driver of longer-term variability driven by changes in wind stress. Summer variability of CO2 was driven primarily by increases in primary production.
