δ¹⁸O record and Th230 dating results of espeleothems from Jaraguá cave, Brazil, 2017

Here we present a new paleo-rainfall reconstruction based on high-resolution speleothem d18O records from the core region of the South American Monsoon System (SAMS), documenting the changing hydrological conditions over tropical South America (SA), in particular during abrupt millennial-scale events.

This new record provides the best-resolved and most accurately constrained geochronology of any proxy from South America for this time period, spanning from the Last Glacial Maximum (LGM) to the mid-Holocene.
