Collaborative Proposal: 2000+ Year Detailed, Calibrated Climate Reconstruction from a South Pole Ice Core Set in an Antarctic-Global Scale Context

该奖项支持一个项目，以检查现有的冰芯的机会，从南极（SPRESO核心），以制定一个2000多年的气候记录。SPRESO冰芯将是一个每年一次的，每年解决过去的气候重建（大气环流，温度，降水率和大气化学），利用连续的，共同注册的测量（n=45）：主要离子，微量元素和稳定同位素系列，加上微粒大小和成分的选定部分。这个项目的智力价值涉及到这样一个事实，即在南极洲存在的这种质量的2000多年的记录很少，尽管在这个关键时期作为理解现代气候的框架的科学兴趣越来越大。这项冰芯调查的科学影响是，它将提供对气候变异性的深入了解;在人类活动的背景下评估现代气候变异性的基线;以及对预测未来气候变异性的贡献。这项工作的更广泛影响是，拟议的研究解决了有关南极洲在过去，现在和未来全球变化中的作用的重要问题。研究结果将通过公开讲座、媒体露面和我们研究所的广泛外联活动转化为公众可获得的信息。我们的冰芯活动为K-12和大学课程提供了主要基础，并为几个基于实地和实验室的研究生论文和本科生项目提供了基础。该项目将支持一名博士生3年和本科生的工资。气候变化研究所在性别和种族多元化的学生和教职员工参与研究方面拥有悠久的历史。

This award supports a project to examine an existing ice core of opportunity from South Pole (SPRESO core) to develop a 2000+ year long climate record. SPRESO ice core will be an annually dated, sub-annually-resolved reconstruction of past climate (atmospheric circulation, temperature, precipitation rate, and atmospheric chemistry) utilizing continuous, co-registered measurements (n=45) of: major ions, trace elements, and stable isotope series, plus selected sections for microparticle size and composition. The intellectual merit of this project relates to the fact that few 2000+ year records of this quality exist in Antarctica despite increasing scientific interest in this critical time period as the framework within which to understand modern climate. The scientific impact of this ice core investigation are that it will provide an in-depth understanding of climate variability; a baseline for assessing modern climate variability in the context of human activity; and a contribution to the prediction of future climate variability. The broader impact of this work is that the proposed research addresses important questions concerning the role of Antarctica in past, present, and future global change. Results will be translated into publicly accessible information through public lectures, media appearances, and an extensive outreach activity housed in our Institute. Our ice core activities provide a major basis for curriculum in K-12 and University plus a basis for several field and laboratory based graduate theses and undergraduate student projects. The project will support one PhD student for 3 years and undergraduate salaries. The Climate Change Institute has a long history of gender and ethnically diverse student and staff involvement in research.
