Collaborative Research: Calibration of Sclerosponges as Proxy Indicators of Environmental Conditions

摘要：该项目将完成一项工作，以校准作为温度和盐度替代物的硬脊椎动物骨骼中的同位素和微量元素化学。这项研究将测量来自牙买加发现湾的硬质回声骨骼中的锶/钙和镁/钙以及氧和碳同位素，这些骨骼以前曾在野外染色，并获得了连续的水温和成分数据。此外，还将分析李斯库金岛不同水深的硬质响应骨骼，以重建温跃层结构。

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.
