From: Deep Equatorial Pacific Ocean Oxygenation and Atmospheric CO2 Over The Last Ice Age
(a) Authigenic U records from the eastern equatorial Pacific Ocean (MV1014-8JC, black circles; MV1014-17JC, red circles). Blue bars represent times of coincident high aU and low CO2 concentrations in 17JC, 13/14PC, and 21PC. (b) Authigenic U composite record from cores TN057-13PC (10–20 kyr) and TN057-14PC (20–70 kyr) from the Southern Ocean (pink circles, Jaccard et al., 20162). (c) Authigenic U record from core TN057-21PC from the South Atlantic Ocean (green circles, authigenic U data from Sachs and Anderson, 200338; age model from Gottschalk et al., 20167). (d) Atmospheric CO2 record from Antarctic ice cores (blue circles; Bereiter et al., 20121). Southern Hemisphere Antarctic Isotope Maxima (AIM) 1–4 are shown.
