High-Resolution Sea Surface Temperature Records in Barbados Corals From Past Interglacial Periods

PI将试图量化的速度和规模的气候和海平面变化在最后一次间冰期使用模式的架构和社区继承的珊瑚礁序列的四个加勒比岛屿在现有的马里兰州大学的集合。 这项研究将确定一个区域模式，以排除局部构造和海洋学的变异性。 这些样品将通过ICP-SMS进行分析，以确定提高的分辨率是否足以根据Sr/Ca和U/Ca比值筛选Th测年和古温度，以检测珊瑚记录中的变化。 将ICP-SMS分析结果与之前的热电离质谱结果进行比较。

The PI will attempt to quantify the rate and magnitude of climate and sea level changes during the last interglacial using patter of architecture and community succession in reef sequences of four Caribbean islands in existing University of Maryland collections. The study will establish a regional pattern to rule out local tectonic and oceanographic variabilities. The samples will be analyzed by ICP-SMS to see if improved resolution is sufficient to screen Th dating and paleotemperatures based on Sr/Ca and U/Ca ratios in order to detect alteration in coral records. Results of the ICP-SMS analyses will be compared to previous thermal ionization mass spectroscopy results.
