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

海平面的历史是人类历史上 古气候和古海洋学参数。 知识 这个变量限制了冰盖的生长历史， 衰变及其与气候强迫的关系。 同样 大气中二氧化碳的历史也对我们的 了解气候。 这项建议要求支持， 解决这两个问题。 本项目将使用样本 从瓦努阿图桑托岛的珊瑚礁台地中发现的 为了获得高分辨率的海平面历史记录 以及过去3万年来14 C/12 C的初始比率。 的 样本来自PI与正在进行的 在桑托岛上钻探的项目，由来自 新喀里多尼亚的ORSTROM。提供了钻井费用 在ORSTROM 这项研究之所以重要，是因为它 将有助于限制海平面的历史， 它将进一步完善我们的14 C年代学， 这个间隔。

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.
