A note on removal of the compaction effect for the 210Pb method

The compaction effect may significantly flatten an excess 210Pb depth profile near the sediment–water interface, resulting in erroneous 210Pb dating. There are three mathematical approaches to correct for the compaction effect. In the present paper, some further deductions have been done to make the procedure of approach calculations more clearly and practically. Meanwhile, the three approaches are also compared using a case study selected from the literature.
