Extended Data Fig. 2: \(\left[ {{{{\mathrm{CO}}}}_3^{2 - }} \right]_{{{{\mathrm{as}}}}}\)/DICas sensitivity vs. \(\left[ {{{{\mathrm{CO}}}}_3^{2 - }} \right]_{{{{\mathrm{Norm}}}}}\).
From: Millennial and centennial CO2 release from the Southern Ocean during the last deglaciation
\(\left[ {{{{\mathrm{CO}}}}_3^{2 - }} \right]_{{{{\mathrm{Norm}}}}}\) = \(\left[ {{{{\mathrm{CO}}}}_3^{2 - }} \right]_{{{{\mathrm{as}}}}}\) + 78. The sensitivity is calculated based on the method from ref. 16. The large circle indicates the average sensitivity (-0.48) for \(\left[ {{{{\mathrm{CO}}}}_3^{2 - }} \right]_{{{{\mathrm{Norm}}}}}\) ranges (shaded region) observed at sites GGC90 and NEAP 4K during the last deglaciation.
