data for submission to GRL by Wu et al.

Excess 210Pb profile styles, sediment accumulation rates derived from 210Pb and 137Cs methods, and the related sampling information used in Figure 1, 2 and 5 were presented in 'Radionuclide data and sampling information.docx'. Grain size composition data used in Figure 3 were presented in 'Grain size composition.xlsx'.用于图1、图2和图5的过剩铅-210（Excess 210Pb）剖面形态、经铅-210（210Pb）与铯-137（137Cs）方法获取的沉积物沉积速率，以及相关采样信息，均收录于《Radionuclide data and sampling information.docx》中。用于图3的粒度组成数据，已收录于《Grain size composition.xlsx》中。
