Records from the Antarctic ice cores. (a) Stack of the δ18Oice records from EPICA (European Project for Ice Coring in Antarctica) Dome C (EDC), EPICA Dronning Maud Land ice core (EDML), and West Antarctic Ice Sheet (WAIS) Divide (WD) ice cores with its 2σ confidence interval59. (b) Concentrations of insoluble mineral dust: in Talos Dome (TALDICE) ice core (black line) for 0.6–1 µm particles57,58; in Taylor Glacier (TG) (grey line) data from Abakus laser particles counter ∼ 0.8–10 μm54; dust concentrations in TG samples measured for particles 0.6–1 µm using Coulter Counter (blue diamonds)8 and by spICP-TOFMS (red circles). (c) spICP-TOFMS total calculated concentrations of Si, Fe, Na and Ca in all particles larger than 0.467 μm and smaller than 2.5 μm.
