SPS + Numbers: measured at CPGeo, University of São Paulo; Numbers: measured at the Laboratory of Geochronology, University of Brasília.
The ages are calibrated by the available 14C-AMS dates (i.e. core GeoB16206-1 and GeoB16224-1), while others (i.e., late Holocene, Mid-Holocene ) are roughly estimated by 14C-constrained age model of sediment cores nearby and/or water depth at which the sediment core was raised.
