variableName: d18O
units: permil
description: carbonate
basis: Weighted mean annual ?18O value for the period from 1988?1996 was ?7.0?, with more neg- ative in summer months (average ~ ?9.5?, SMOW) and more positive ?18O in winter months (average ~ ?4.5?, SMOW). Therefore, more negative ?18O values are consistent with a greater contribution of summer rainfall
direction: negative
interpDirection: negative
scope: climate
seasonality: Summer
seasonalityOriginal: summer
variable: precipitation
variableDetail: East Asian summer monsoon strength; more negative values of d18O are interpreted as indicative of increased monsoon precipitation
variableGroup: P
variableOriginal: Precipitation_amount
scope: climate
scope: climate
coefficient: NA
direction: positive
equilibriumEvidence: Given differences in dating errors and resolution, the ?18O records are virtually identical during contemporaneous growth periods, providing a robust replication test for equilibrium calcite deposition.
