Direct North-South synchronization of abrupt climate change record in ice cores using beryllium 10
International audience A new, decadally resolved record of the 10 Be peak at 41 kyr from the EPICA Dome C ice core (Antarctica) is used to match it with the same peak in the GRIP ice core (Greenland). This permits a direct synchronisation of the climatic variations around 41 kyr BP, independent of u...
