Extended Data Fig. 1: Corrected and calibrated radiocarbon age models for U1357B and MD03-2601.
From: Sensitivity of Holocene East Antarctic productivity to subdecadal variability set by sea ice
Age Model for U1357B (blue symbols show calibrated and corrected ages, and blue line of calculated Bayesian age-depth curve, using BACON R package; dotted lines are 2 sigma uncertainty) and MD03-2601 (red symbols and lines as for U1357B) show that sediment advection is a regional signal as sedimentation rates covary. Compound specific ages from U1357A are shown in green with 2 sigma uncertainties. U1357B is a longer core with 87 14C dates, leading to a much higher resolution age model. U1357B also includes the last 1,000 years, which is lacking in MD03-2601.
