10Be evidence for the Matuyama–Brunhes geomagnetic reversal in the EPICA Dome C ice core

Nature volume 444, pages 82–84 (2006)Cite this article

Abstract

An ice core drilled at Dome C, Antarctica, is the oldest ice core so far retrieved1. On the basis of ice flow modelling and a comparison between the deuterium signal in the ice with climate records from marine sediment cores, the ice at a depth of 3,190 m in the Dome C core is believed to have been deposited around 800,000 years ago2, offering a rare opportunity to study climatic and environmental conditions over this time period. However, an independent determination of this age is important because the deuterium profile below a depth of 3,190 m depth does not show the expected correlation with the marine record2. Here we present evidence for enhanced 10Be deposition in the ice at 3,160–3,170 m, which we interpret as a result of the low dipole field strength during the Matuyama–Brunhes geomagnetic reversal, which occurred about 780,000 years ago. If correct, this provides a crucial tie point between ice cores, marine cores and a radiometric timescale.
