Orbital forcing drives both the South American monsoon and local water balance in the central Andes during interglacials

This dataset presents stable isotope data (d13C, d17O, d18O, D47, D’17O) from lake cores from Lake Junin spanning Marine Isotope Stage 15 (MIS 15). Carbonate clumped and triple oxygen isotope measurements were made at the University of Michigan Isotopologue Paleosciences Lab on a Nu Perspectives mass spectrometer. We used the procedure of Passey et al. (2010) for clumped isotope measurements and report data on the ICDES90 scale. We used the procedure of Passey et al. (2014) for triple oxygen isotope measurements and report data on the VSMOW-SLAP scale.
