Extended Data Fig. 4: Comparison of millennial-scale variability in the Junín piston core with regional cave records of hydroclimate and Greenland air temperature during MIS 2, 3 and 6.

From: 700,000 years of tropical Andean glaciation

Extended Data Fig. 4

High-resolution MS is a proxy for siliciclastic flux and regional ice extent (see Methods and Extended Data Fig. 2) and organic matter content is an inverse proxy for the hydrologic balance of Lake Junín1. a–e, Expanded views of the 20–50-ka (MIS 2 and 3) interval. f–j, Expanded views of the 130–190-ka (MIS 6) window. d, Pacupahuain Cave (Fig. 1) speleothem record26. e, Greenland δ18O record49. i, Huagapo Cave (Fig. 1) speleothem record31. j, Synthetic Greenland δ18O record32. Dashed lines in a–e illustrate the temporal connection between Dansgaard–Oeschger (DO) events in Greenland ice cores and intervals of drying and deglaciation in the tropical Andes.
