description: carbonate
interpDirection: increase
scope: climate
variable: effectivePrecipitation
variableDetail: LakeLevel@surface
direction: negative
variableGroup: P-E
seasonality: Annual
seasonalityGeneral: Annual
basis: 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.
direction: negative
equilibriumEvidence: 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

integrationTimeUnits: years
rank: 1
scope: isotope
variable: effectivePrecipitation
variableGroup: EffectiveMoisture
variableGroupOriginal: P_E
variableGroupDirection: negative
basis: Increased seasonality (hotter and drier summers, cool wet winters) lead to periods of increased E/P, and increased variability in ostracod ?18O.
