中文摘要
该项目将应用离子微探针对约翰斯顿环礁(太平洋中部)和2英里珊瑚礁(南非)的波利茨珊瑚进行分月分辨率的微量元素(B、F、镁、锶)和氧同位素的分析。目标有两个:确定微量元素之间的协变,以评估它们与水温的关系,并检查珊瑚生长几何形状与地球化学示踪剂之间的关系。将在每个地点分析几个菌落,以检查当地的可变性,并提供水温的仪器记录。
英文摘要
This project will apply ion microprobe analyses to examine variation of trace elements (B, F, Mg, Sr) and oxygen isotopes at sub-monthly resolution in Porites corals from Johnston Atoll (central Pacific) and Two-Mile Reef (South Africa). The goals are twofold: to determine covariation among trace elements in order to assess their relationship to water temperature, and to examine the relationship between coral growth geometry and the geochemical tracers. Several colonies will be analyzed at each site to examine local variability and instrumental records of water temperature are available.
