From: East Greenland ice core dust record reveals timing of Greenland ice sheet advance and retreat
Dust size distributions in RECAP and NGRIP ice cores. RECAP dust size distributions were measured by Coulter Counter. The glacial data cover the time period (12,800–33,900) ± 500 years b2k, while the Holocene covers selected samples from the period (356 ± 2 − 4010 ± 50) years b2k. A power law is fitted to the Holocene data from 4 to 6 μm and extrapolated to 0.9 μm, with the residual Holocene dust relative to the power law fit shown in red. It is interpreted as the size distribution of the RECAP remote Holocene dust. The coloured shadings around the curves are 1σ errors. The grey bars show the size ranges assigned to represent small and large particles in the RECAP dust time series. The yellow area shows the size range of particles sampled for Sr and Nd isotope measurements
