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.
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
