DK: 18O on ostracodes. Another time series is published on gastropods. The two are very similar.

Individual gastropod shells were also picked from every 1-cm interval for stable isotopic analysis. Single specimens of Pyrgophorus coronatus were separated from the sieved 1400 mm fraction under 101 magnification. Gastropod shells were soaked in 15% H2O2 to remove organic matter cleaned and sonicated in deionized water, and ultimately rinsed with methanol before drying. Individual gastropod shells were ground to a fine powder using a mortar and pestle

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)
