摘要:本项目将完成对海绵动物骨骼中同位素和微量元素化学作为温度和盐度代用物的校准工作。该研究将测量来自牙买加Discovery Bay的硬化剂海绵骨骼的Sr/Ca和Mg/Ca以及O和C同位素,这些骨骼以前在野外染色,并且可以获得连续的水温和成分数据。此外,还将分析李氏岛不同水深的硬骨海绵骨骼,重建温跃层结构。
英文摘要
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.
