Causes and timing of the 8200 yr BP event inferred from the comparison of the GRIP Be-10 and the tree ring Delta C-14 record
We analyse the 8200 yr BP cold event by comparing the high-resolution Be-10 record from the GRIP ice core from Central Greenland with the well-known tree ring Delta(14)C record. By transferring the absolute dated tree ring chronology to the ice core time scale, we show that the coldest phase in the GRIP record occurred around 8150 yr BP. Furthermore, this method allows us to disentangle production
