If the d18O signal is controlled mainly by E/P, then the variation in d18O during the late Holocene suggests repeated multi-decadal wet/dry cycles that are superimposed upon longer-term, millennial patterns of abundant rainfall and drought.

This is demonstrated for Lake Punta Laguna by comparing the measured d18O values of lakewater, rainfall, and groundwater. Local groundwater and rainwater have depleted d18O values of 03.91 and 03.92?, respectively, whereas the lakewater is significantly enriched, averaging 0.93? (Table 3)
