Fig. 3: Estimated change in the regenerated carbon as a fraction of the change in the sequestered carbon ( $$\frac{\Delta {m}_{reg}}{\Delta {m}_{seq}}$$ Δ m r e g Δ m s e q ) as a function of the assumed change in the fraction of Northern-sourced water (Δα).The alternative text for this image may have been generated using AI.

Δα = 0 corresponds to no LGM to Holocene change in the water-mass configuration, whereas Δα = 0.3 corresponds to Northern-sourced water being confined to the upper 2000 m of the Atlantic at the Last Glacial Maximum. The shaded area indicates the 2-σ uncertainty interval of the estimate.
