Methodology
  • Radiocarbon analysis was conducted on terrestrial macrofossils via accelerator mass spectrometry at the W.M. Keck Carbon Cycle AMS facility at the University of California, Irvine. Ages were calibrated using IntCal13 and age models were created using the R package "bacon."

  • 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.
Description
  • This dataset presents stable isotope data (d13C, d18O, D47, D17O) from Holocene lake cores from three lakes in the Peruvian Andes (Lakes Junin, Pumacocha, and Mehcocha). We also present new radiocarbon (14C) data and core age models for Lakes Junin and Mehcocha. We use these data to explore trends in lake water temperatures and evaporative state (i.e., water balance) over the Holocene. Our clumped isotope (D47) results suggest lake water temperatures at all three lakes were stable over the Holocene and similar to present day lake temperatures. Our triple oxygen isotope (D’17O) results illustrate that lake water balance at all three lakes was variable over the Holocene and tracks changes in austral summertime insolation, suggesting a connection between central Andean water balance and the South American summer monsoon (SASM).
