Extended Data Fig. 2: Beryllium isotope record comparison.
From: Near-synchronous Northern Hemisphere and Patagonian Ice Sheet variation over the last glacial cycle
Beryllium isotope records (mean values) from (a) Site J1002 (this study, black circles, 2σ propagated uncertainty), (b) the west equatorial Pacific Ocean (normalized data, orange, 2σ uncertainty)23 and (c) the mixed North Atlantic and Mediterranean outflow (red, 10 % uncertainty)15. (d) The relative paleo-production of 10Be converted from paleomagnetic reference records of the geomagnetic dipole moment64 prior to 10 ka and the stacked record of 10Be production65 post 10 ka following von Blanckenburg et al.15 (yellow, 1σ uncertainty). (e) The benthic oxygen isotope stack from Lisiecki and Raymo55 is presented for comparison (blue). The mean 10Be/9Be ratios from Site J1002 (dashed grey line) are presented along with values that have been corrected using the relative 10Be paleo-production record presented in d.
