Therefore, the Challa ?18Odiatom record is tuned to the underlying processes of local precipitation and, especially, seasonal evaporative losses from the lake surface, only modifi ed by small temperature effects.

An adjustment of ?0.2?/i¿½C increases d18Odiatom by 1? from 25 ka to 16 ka and by 0.5? during the late-glacial period and Younger Dryas, values still less than that during the late Holocene (Fig. 3).

SEM of calcite crystals to identify contamination by detrital limestone

modern d18O.lakewater and d18O.calcite identical within error

d18O.precipitation over tropical South America controlled by Raleigh-type fractionation (see Vuille & Werner 2005)

primarily controlled by intensity of South America summer monsoon

exclusion of all other possible influencing processes (see Bird et al. 2011)
