An improved north-south synchronization of ice core records around the 41kyr 10Be peak ...
Using new high-resolution 10Be measurements in the NGRIP, EDML and Vostok ice cores, together with previously published data from EDC, we present an improved synchronization between Greenland and Antarctic ice cores during the Laschamp geomagnetic excursion ∼ 41kyr ago. We estimate the precision of...
