A note on removal of the compaction effect for the 210Pb method.
The compaction effect may significantly flatten an excess (210)Pb depth profile near the sediment-water interface, resulting in erroneous (210)Pb 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.
