Teal-colored points represent two ‘modern’ age that can be calibrated and 2017 when the core was raised. a Bayesian convergence iterations used to determine the most likely age of each depth; b accumulation rate (yr/cm) of samples within the core (mean and variance); c temporal autocorrelation analysis (memory) that assess how much sedimentation rates changes within the core (with 0 being no autocorrelation and changing slopes and 1 being a linear sedimentation throughout the core); d inferred depth-age relationship; e a simplified stratigraphy of the sedimentary core from Lake Cormorán. Colored bands approximate the actual colors found in the sedimentary gyttjas but cannot capture the fineness of laminae.
