项目摘要

This ESH award will support a team of investigators to address three separate project, each combining the use of radiochemical dating techniques (14C, 230Th and 231Pa) with stable isotope and trace element analysis of corals and speleothems. Projects include: (1) Calibration of the radiocarbon time scale between 10,000 and 48,000 years BP using previously-collected corals from Papua New Guinea and speleothems from the Bahamas; (2) Establish a high-resolution climated record for the mid-continent of North America from Missouri speliothems; (3) Determine the age and sea-level history for the Penultimate deglaciation (Termination II) using coral outcrops in Barbados.

该ESH奖将支持一个调查人员团队解决三个单独的项目，每个项目都结合了放射化学约会技术（14C，230和231PA）的使用以及稳定的同位素和珊瑚和辣表示的痕量元素分析。项目包括：（1）使用巴布亚新几内亚的先前收集的珊瑚和巴哈马的speleothems对放射性碳时间量表的校准；（2）从密苏里州的Speliothems为北美中部的高分辨率气候记录建立；（3）确定使用巴巴多斯的珊瑚露头倒数第二次脱水的年龄和海平面历史。
