摘要

摘要:
放射性核素示踪技术被广泛应用于海洋学研究。海洋沉积物是许多物质的归宿，海洋沉积过程的研究常关注3个关联问题：物质来源、沉积速率、再悬浮过程。针对这3个问题，在南海9个珊瑚礁区、北部湾涠洲岛海域、珠江口、北冰洋、南大洋等多个海区利用典型的铀系放射性核素（²¹⁰Pb、²²⁶Ra、²³⁴Th、²³⁸U）示踪技术开展海洋沉积过程研究。物源识别方面，研究发现珊瑚礁区沉积物具有极低的²²⁶Ra/²³⁸U活度比值（＜0.1），显著低于其他海区的²²⁶Ra/²³⁸U活度比值（0.5～1.0），该独特性质可以应用于珊瑚礁区的沉积物/悬浮物来源示踪，是其他传统元素地球化学方法（Al、Ti、稀土元素）的补充。沉积速率方面，基于²¹⁰Pb的恒定通量恒定沉积速率（Constant Flux Constant Sedimentation Model, CFCS）模式，定量计算了广西涠洲岛珊瑚礁区沉积柱样的沉积速率（3.7±0.6 mm/a），该结果低于中国多个近岸海域的沉积速率（5～96 mm/a）。沉积物再悬浮方面，提出利用“残余²³⁴Th”（不同于过剩²³⁴Th）示踪海洋沉积物再悬浮过程，并成功应用于北冰洋、南海、南大洋。

Abstract:
Radionuclides are widely used as tracers in oceanography. As the final fate of many substances, marine sediment is mainly concerned from three perspectives: source identification, sedimentation rate, and sediment resuspension. In the present study, uranium-series radionuclides (²¹⁰Pb, ²²⁶Ra, ²³⁴Th, and ²³⁸U) are applied in several sea regions such as the nine typical coral reefs in the South China Sea, the Weizhou Island, the Pearl River Estuary, the Arctic Ocean, and the Southern Ocean, to study the sediment source, sedimentation rate, and sediment resuspension. Firstly, activity ratio of ²²⁶Ra to ²³⁸U was found extremely low (＜0.1) in the marine sediment of coral reef regions comparing to the activity ratios (0.5～1.0) in other marine sediments and therefore, it could be used as the tool to identify the sources of marine sediments from coral reef regions in addition to other geochemical tools (Al, Ti, and REE). Secondly, the sedimentation rate (3.7±0.6 mm/a) was calculated for a sediment core taking from the coral reefs near the Weizhou Island via excess ²¹⁰Pb (Constant Flux Constant Sedimentation Model, CFCS model in brief) which was lower than most figures (5 mm/a～96 mm/a) in other coastal areas of China. Finally, residual β activity of particulate ²³⁴Th (RA_P234) was proposed for tracking marine sediment resuspension. The RA_P234 was successfully applied in the Arctic Ocean, South China Sea, and Southern Ocean. In conclusion, the successful applications of these radioactive tracers have provided potential tools used for tracing marine sedimentary processes in addition to the ongoing toolbox.
