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、古海洋参数之一。对这一变量的了解制约了冰盖消长的历史，以及它与气候强迫的关系。同样，大气中二氧化碳的历史对于我们理解气候也是至关重要的。该提案要求提供支持，以解决这两个问题。该项目将使用从瓦努阿图桑托岛珊瑚礁阶地回收的样品，以获得海平面历史的高分辨率记录和过去30 000年的14C/12C初始比率。这些样本是由来自新喀里多尼亚ORSTROM的科学家领导的PIS与正在进行的圣托岛钻探项目合作产生的。钻探的成本由ORSTROM提供。这里提出的这项研究很重要，因为它将有助于限制最后一次冰川消融期间的海平面历史，并将进一步完善这段时间的14C年代学。

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.
