1042883/MayewskiThis award supports a project to analyze a deep ice core which will be drilled by a New Zealand research team at Roosevelt Island. The objectives are to process the ice core at very high resolution to (a) better understand phasing sequences in Arctic/Antarctic abrupt climate change, even at the level of individual storm events; (b) determine the impact of changes in the Westerlies and the Amundsen Sea Low on past/present/future climate change; (c) determine how sea ice extent has varied in the area; (d) compare the response of West Antarctica climate to other regions during glacial/interglacial cycles; and (e) determine how climate of the Ross Sea Embayment changed during the transition from Ross Ice Sheet to Ross Ice Shelf. The intellectual merit of the RICE deep ice core project is that it is expected to provide a 30kyr long (and possibly 150kyr long) extremely high-resolution view of climate change in the Ross Sea Embayment Region and data essential to test and understand critical questions that have emerged as a consequence of the recent synthesis of Antarctic and Southern Ocean climate change presented in the Scientific Commission for Antarctic Research document: Antarctic Climate Change and the Environment (ACCE, 2009). Ice core processing and analysis will be performed jointly by University of Maine and the collaborators from New Zealand. Co-registered sampling for all chemical analyses will be accomplished by a joint laboratory effort at the IGNS NZ ice core facility using a continuous melter system developed by the University of Maine. The RICE deep ice core record will provide information necessary in unraveling the significance of multi-millennial underpinning for climate change and in the understanding of observed and projected climate change in light of current dramatic human impact on Antarctica and the Southern Ocean. The broader impacts of the project include the fact that two CCI graduate students will be funded through the project, and will be involved in all aspects of field research, core sampling, sample processing, analytical and numerical analyses, data interpretation, writing of manuscripts, and presentation of results at national and international conferences. Data and ideas developed in this project and associated work will be used in several courses taught at the University of Maine. Innovative cyberinfrastructure will be incorporated into this work and ground breaking analytical technologies, and data access/storage tools will be used.

1042883/Mayewski 该奖项支持一个分析深层冰芯的项目，该项目将由新西兰研究小组在罗斯福岛钻探。目标是以非常高分辨率处理冰芯，以便（a）更好地了解北极/南极气候突变的阶段序列，甚至在单个风暴事件的水平上； (b) 确定西风带和阿蒙森海低压的变化对过去/现在/未来气候变化的影响； (c) 确定该地区海冰范围的变化情况； (d) 比较冰期/间冰期循环期间南极洲西部气候与其他区域的响应； (e) 确定罗斯海海湾的气候在从罗斯冰盖到罗斯冰架的过渡过程中如何变化。 RICE深冰芯项目的智力优势在于，预计它将提供罗斯海海湾地区气候变化的30kyr长（可能是150kyr长）的极高分辨率视图，以及测试和理解关键问题所必需的数据。南极研究科学委员会的文件：南极气候变化与环境（ACCE，2009 年）中提出了最近对南极和南大洋气候变化的综合结果。 冰芯处理和分析将由缅因大学和新西兰的合作者联合进行。 所有化学分析的联合登记采样将由 IGNS NZ 冰芯设施的联合实验室使用缅因大学开发的连续熔化器系统完成。 RICE深冰芯记录将提供必要的信息，以揭示气候变化的千年基础的重要性，并根据当前人类对南极洲和南大洋的巨大影响来理解观测到的和预测的气候变化。该项目更广泛的影响包括两名 CCI 研究生将通过该项目获得资助，并将参与实地研究、岩心取样、样本处理、分析和数值分析、数据解释、手稿撰写等各个方面。并在国内和国际会议上介绍成果。 该项目和相关工作中开发的数据和想法将用于缅因大学教授的几门课程。这项工作将纳入创新的网络基础设施和突破性的分析技术，并将使用数据访问/存储工具。
