Lead 210 or climatic changes at South Pole?
International audience The 21øpb concentration has been measured in 92 adjacent firn samples collected at the South Pole along a 18 m depth profile. The decay analysis shows that significant changes happened around 1920 and 1954 either in the accumulation rate or in the 21 0pb content of the new fal...

Summary: | International audience The 21øpb concentration has been measured in 92 adjacent firn samples collected at the South Pole along a 18 m depth profile. The decay analysis shows that significant changes happened around 1920 and 1954 either in the accumulation rate or in the 21 0pb content of the new fallen snow. |
