Summary: This project will complete an effort to calibrate isotope and trace element chemistry in the skeletons of sclerosponges as proxies for temperature and salinity. The study will measure Sr/Ca and Mg/Ca as well as O and C isotopes in sclerosponge skeletons from Discovery Bay, Jamaica previously stained in the field and for which continuous water temperature and composition data are available. In addition sclerosponge skeletons from different water depths at Lee Stocking Island will be analyzed to reconstruct the thermocline structure.

摘要：该项目将完成校准硬化海绵骨骼中的同位素和微量元素化学的工作，作为温度和盐度的代理。 该研究将测量来自牙买加愉景湾的硬化海绵骨骼中的 Sr/Ca 和 Mg/Ca 以及 O 和 C 同位素，这些骨骼先前在现场染色，并且可以获得连续的水温和成分数据。 此外，还将对李斯托金岛不同水深的硬化海绵骨架进行分析，以重建温跃层结构。
