Extended Data Fig. 2: δ13CFA, monsoon indices, and sea surface temperature (SST) at Site U1446 during the last 1.46 Myr.

From: Increased interglacial atmospheric CO2 levels followed the mid-Pleistocene Transition

Extended Data Fig. 2

a, Monsoon indices: normalized values of Indian summer monsoon (ISM) records based on the seawater δ18O (reversed δ18Osw U1446)25 at Site U1446, seawater δ18O of the Andaman Sea (reversed δ18Osw Andaman Sea)67, difference between surface and thermocline foraminifera δ18O (Δδ18O) in the equatorial Indian Ocean68, Indian summer monsoon (I.S.M.) stack of the Arabian Sea69,70. b and e, δ13CFA and U1446 δ18Osw. c and f, δ13CFA and the U1446 TEX86H-based SST25. d, CO2FA and the western Pacific warm pool (WPWP) SST. The SSTs in the WPWP were averaged (Sites ODP Site 80623,71 and MD97-214072). Thick lines indicate the 200-kyr running mean.
