variableName: d18O
units: permil
description: cellulose
scope: climate
direction: negative
seasonality: Annual
variable: effectivePrecipitation
variableDetail: lakebalance@surface
seasonalityGeneral: Annual
variableGroup: P-E
basis: The lake was probably hydrologically closed until ?800 cal yr BP, but experienced higher lake levels ?9000e7500 and ?3300e800 cal yr BP and low lake levels during the intervening times
direction: negative
inferredMaterial: lake water
integrationTime: ~12
integrationTimeUnits: months (groundwater rather than precipitation fed)
rank: 1
scope: isotope
variable: hydrologicBalance
variableGroup: EffectiveMoisture
variableGroupOriginal: I_E
variableGroupDirection: negative
basis: Monitoring of the isotopic composition of modern lake water and precipitation shows that, at present, the lake water traces the isotopic composition of precipitation, modified by a slight evaporative enrichment during the open-water season and a minor snowmelt signal.
