Research on Groundwater Discharge into Wuyuan Bay

Abstract

海底地下水排泄(SGD)是一个重要的陆海相互作用过程。本论文依托国家自然科学基金《近岸海域的海底地下水排泄及其海洋生态环境效应研究(40672166)》,以位于厦门岛东北部的五缘湾作为研究对象,运用天然的放射性核素(224Ra、226Ra、222Rn)示踪技术评估其海底地下水输入通量。 通过构建224Ra和226Ra的质量平衡模型,量化了除SGD外其他主要源汇项,间接地估算了五缘湾内、外湾的地下水输入通量,同时获得五缘湾内、外湾的海水回流率分别为0.87和0.74;利用镭同位素的比值法,估算了五缘湾内、外湾的水体平均停留时间分别为3.56d和2.65d,并基于水体停留时间计算了五缘湾内、外湾...Submarine groundwater discharge(SGD)has been considered as a potentially significant land-ocean interaction. In this thesis, Wuyuan Bay located in the northeastern of Xiamen island was chosen as a place to conduct SGD research, using the naturally occurring radioactive tracers(224Ra、226Ra、222Rn). Through constructing 224Ra and 226Ra mass balance models and quantifying the main sources and sinks o...学位:理学硕士院系专业:海洋与环境学院海洋学系_海洋地质学号:2242008115151
