英文摘要: 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 ĝ1/4 ĝ€41ĝ€kyr ago. We estimate the precision of this synchronization to be ±20 years, an order of magnitude better than previous work. We discuss the implications of this new synchronization for making improved estimates of the depth difference between ice and enclosed gas of the same age (Î"depth), difference between age of ice and enclosed gas at the same depth (Î"age) in the EDC and EDML ice cores, spectral properties of the 10Be profiles and phasing between Dansgaard-Oeschger-10 (in NGRIP) and AIM-10 (in EDML and EDC). © Author(s) 2017. 资助项目: ERC, European Research Council
