dc.description.abstract<正>Measurement of 228Ra activities in the upper 300 m water column was conducted at two stations in the South China Sea using an MnO2-fiber extraction/p-counting technique of 228Ac. Results showed that 228Ra activities ranged from 0.38 to 3.60 Bq · m-3. The vertical profiles of 228Ra at the time-series station favored a steady state assumption. Based on a one-dimensional steady state model, 228Ra-nitrate coupled approach was applied to stations NS97-43, NS99-53 (T1, NS99-53 (T2). New production thus quantif...zh_CN
