Fig. 1: Atmospheric CO2 and atmospheric and oceanic δ13C exhibit distinct patterns across the last deglaciation.

From: Carbon isotope budget indicates biological disequilibrium dominated ocean carbon storage at the Last Glacial Maximum

Fig. 1

a Measured atmospheric pCO2 (in red, reproduced from ref. 35) from 20 to 6 kyr before present. b Measured atmospheric (red, left vertical axis, reproduced from ref. 36) and ocean-average (purple, right vertical axis, reproduced from ref. 31) δ13C from 20 to 6 kyr before present. The vertical arrows indicate the larger δ13C difference between the ocean (δo) and atmosphere (δa) during the Holocene than at the Last Glacial Maximum. A map with the locations of the 127 core sites used for the ocean-average δ13C was provided in ref. 31. In both panels, shaded areas indicate 2-σ uncertainty intervals of the measurements. Note that the vertical axes have different scales and that time runs forward to the right.
