Collaborative Research: Detailed Records of Initial 14C andSea Level During Deglaciation by Drilling into a Rapidly Uplifting Reef on Vanuatu

海平面历史是最重要的古气候和古海洋参数之一。对这一变量的了解限制了冰盖生长和衰减的历史，以及它与气候强迫的关系。同样，大气中二氧化碳的历史对我们理解气候也至关重要。本提案要求支持解决这两个问题。该项目将使用从瓦努阿图圣岛的珊瑚礁梯田中回收的样本，以获得过去3万年的海平面历史和初始14C/12C比率的高分辨率记录。这些样本是PIs与新喀里多尼亚ORSTROM科学家领导的圣岛钻探项目合作的结果。钻探费用由奥斯特罗姆公司提供。这里提出的研究很重要，因为它将有助于限制最后一次冰川消退期间的海平面历史，并将进一步完善我们在这段时间内的14C年表。

The history of sea level is one of the most important paleoclimatic and paleoceanographic parameters. Knowledge of this variable constrains the history of ice sheet growth and decay, and its relationship to climate forcing. Likewise the history of CO2 in the atmosphere is also critical to our understanding of climate. This proposal requests support to address both of these issues. This project will use samples recovered from the coral reef terraces of Santo Island, Vanuatu, in order to obtain a high-resolution record of sea level history and initial 14C/12C ratios for the last 30,000 years. The samples result from collaboration of the PIs with an ongoing project of drilling on Santo Island led by scientists from ORSTROM in New Caledonia. The costs of the drilling are provided by ORSTROM. The research proposed here is important because it will help to constrain the history of sea level during the last deglaciation and it will further refine our 14C chronology during this interval.
