Extended Data Fig. 5: Global thermocline salinity anomalies.
From: Atmospheric CO2 control of spontaneous millennial-scale ice age climate oscillations

The stadial salinity anomaly of each the experiments with different levels of CO2 differenced from the ensemble mean of the four experiments. The average salinity in the top 1000 meters of the ocean in each experiment is averaged and then differenced from the ensemble mean average salinity in the top 1000 meters.
