该项目将应用离子微探针分析,以次月分辨率检查约翰斯顿环礁(中太平洋)和两哩礁(南非)的滨珊瑚中微量元素(B、F、Mg、Sr)和氧同位素的变化。 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,并研究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,以检查当地的变异性,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.
