TSid: LS09SCMI
variableName: d18O
units: permil
description: silica
basis: Late Holocene excursions to lower d18Odiatom values suggest a reduc- tion of south-to-north storm trajectories delivered by meridional flow, which likely corresponds to pro- longed intervals when the Aleutian Low pressure system weakened.
scope: climate
variable: surfacePressure
variableGroup: surface pressure
scope: climate
scope: climate
basis: Shifts of d18Odiatom values are likely not related to changes in diatom taxa or dissolution effects. Modern lake water falls along meteoric water line for the region
