Geochronology of the Kusai Lake sediment core.
(a) A linear model fit of 14C age versus depth. The 14C ages showed a reservoir effect of about 3030 years, which is in agreement with a previously published reservoir effect for Kusai Lake4; (b) A Bayesian age-depth model of the Kusai Lake sediment core. This model was used for obtaining ages of all sub-samples.
