中文摘要
该项目将检查从赤道太平洋中部的圣诞环礁(Kirtimati)收集的珊瑚(Sr/Ca和18o)的地球化学,这些珊瑚跨越了7- 13ka的冰期,以评估该时期海洋表面温度和盐度的区域变化。该项目将测试一个假设,即在11.7 Ka之前,当西太平洋的大片大陆架暴露出来时,热带太平洋的温度比今天更低,ENSO条件没有发生。对优势物种风信子的Sr/Ca和SST的校准将在史密森学会和圣诞环礁收集的标本上进行。
英文摘要
This project will examine geochemistry of corals (Sr/Ca and 18 O) collected from Christmas Atoll (Kirtimati) in the central equatorial Pacific spanning the deglacial period 7-13 Ka to assess regional changes in sea surface temperature and salinity over that time. The project will test the hypothesis that prior to 11.7 Ka, when the large shelf areas of the western Pacific were exposed, tropical Pacific temperatures were cooler than today and ENSO conditions did not occur. A calibration of Sr/Ca versus SST in the dominant species, A. hyacinthus, will be done on speciments from the Smithsonian collection as well as those collected at Christmas Atoll.
