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

Luke Gregor, Schalk Kok, and Pedro M. S. Monteiro

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.
