Accumulation rate plotted against mean ¹⁰Be concentrations for different periods during the Holocene.

The listed accumulation rates cover the corresponding period of the ¹⁰Be concentrations within the Holocene for each measurement point, however the spanned time period can differ between the different sites. It should be noted that different standards have been used for some of the samples when calculating the concentrations, as well as different measuring procedures (filtering, no filtering of the samples etc.), which can result in an error of ±10% between the different cores. The red ring shows the mean Eemian ¹⁰Be concentration of 1.13 × 10⁴ atoms/g_ice on the correlation line and indicates annual precipitation of around 0.35 to just above 0.4 m ice equivalent at NEEM during the Eemian. It should be noted that Milcent and Renland, plot A, are situated far from the ice divide why they are removed from plot B where only sites at or close to the ice divide are included.
