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.

该奖项支持一个项目，旨在检查南极（Spreso Core）的现有机会核心，以发展2000多年的气候记录。 Spreso Ice Core将使用连续的，共同注册的测量值（n = 45）的过去气候（大气循环，温度，降水率和大气化学）每年进行的，次生分辨的重建（大气循环，温度，降水速率和大气化学）：主要离子，微量元素，痕量元素，痕量元素和稳定的同位素系列，以及选择的同位素尺寸和构图。该项目的智力优点涉及以下事实：尽管在这个关键时期内越来越多地科学兴趣，但在南极的2000多年记录中，这种质量的记录是了解现代气候的框架。这项冰核研究的科学影响是，它将对气候变异性提供深入的理解。在人类活动背景下评估现代气候变异性的基准；以及预测未来气候变化的贡献。这项工作的更广泛的影响是，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。结果将通过公开讲座，媒体出场和我们研究所中广泛的外展活动转化为公开访问的信息。我们的ICE核心活动为K-12和大学的课程提供了主要的基础，以及几个基于实验室和实验室的研究生论文和本科生项目的基础。该项目将支持一名博士生3年和本科薪水。气候变化研究所拥有性别和种族多样化的学生和员工参与研究的悠久历史。
