Australian ostracods precipitate calcite with approximately an 0.7 permil increase in d18O relative to their source water (Chivas et al., 2002). Large isotopic shifts (up to 8?) preserved in this record suggest that any intra- or inter-species variability is significantly dampened

Trace metal analysis indicates that ostracods are generally formed of low-Mg calcite

Ostracods samples pretreated with 3% H2O2, then samples were split using a microsplitter.
The rates of change of enrichment and depletion of both d18O and d13C (with respect to VPDB) are rapid, indicating large and rapid changes in the lake water due to variations in E/P.
Australian ostracods precipitate calcite with approximately an 0.7 ? increase in ?18O relative to their source water (Chivas et al., 2002). Large isotopic shifts (up to 8?) preserved in this record suggest that any intra- or inter-species variability is significantly dampened
Increased seasonality (hotter and drier summers, cool wet winters) lead to periods of increased E/P, and increased variability in ostracod ?18O.
