Collaborative Research: A 1500m Ice Core from South Pole

1142517/Saltzman该提案要求支持一个从南极洲南极钻取新冰芯的项目。 南极冰芯将被钻到1500米的深度，提供大约40 kyrs的环境记录。 这一核心将使用一种新的中间钻来回收，这种中间钻正在由美国冰钻设计和操作（IDDO）小组与丹麦科学家合作开发。 该提案寻求支持，以提供：（1）南极冰芯项目的科学管理和监督，（2）冰芯钻探和冰芯处理人员，（3）数据管理，（3）通过科学讲习班进行科学协调和沟通。 这项工作的智力价值在于，对极地冰中稳定同位素、大气气体和气溶胶携带的化学物质的分析提供了关于气候变化和气候强迫随时间变化的幅度和时间的独特信息。 国际冰芯研究界已明确提出了在南极洲和格陵兰岛建立冰芯空间阵列的目标，以便能够重建气候变化的区域模式，从而更深入地了解推动气候变化的机制。 该项目的更广泛影响包括获得南极冰芯将支持广泛的冰芯科学项目，这将有助于社会对气候的基本了解以及预测长期气候和冰盖稳定性的能力。 其次，该项目将通过为研究生和博士后研究人员提供实地和核心处理经验的机会，帮助培养下一代冰芯科学家。 华盛顿大学的一名博士后研究员将直接得到该项目的支持，其他许多年轻科学家将通过个人科学提案与该项目互动。 第三，该项目将导致开发一种新的中间钻，这将成为美国冰芯科学界的重要资源。 这一钻探将有一个轻的后勤足迹，这将使广泛的冰芯项目进行，目前是不可行的。 最后，虽然该项目不要求为外联活动提供资金，但该项目将举办讲习班，鼓励并促成协调外联的建议 南极冰芯科学小组的活动。

1142517/SaltzmanThis proposal requests support for a project to drill and recover a new ice core from South Pole, Antarctica. The South Pole ice core will be drilled to a depth of 1500 m, providing an environmental record spanning approximately 40 kyrs. This core will be recovered using a new intermediate drill, which is under development by the U.S. Ice Drilling Design and Operations (IDDO) group in collaboration with Danish scientists. This proposal seeks support to provide: 1) scientific management and oversight for the South Pole ice core project, 2) personnel for ice core drilling and core processing, 3) data management, and 3) scientific coordination and communication via scientific workshops. The intellectual merit of the work is that the analysis of stable isotopes, atmospheric gases, and aerosol-borne chemicals in polar ice has provided unique information about the magnitude and timing of changes in climate and climate forcing through time. The international ice core research community has articulated the goal of developing spatial arrays of ice cores across Antarctica and Greenland, allowing the reconstruction of regional patterns of climate variability in order to provide greater insight into the mechanisms driving climate change. The broader impacts of the project include obtaining the South Pole ice core will support a wide range of ice core science projects, which will contribute to the societal need for a basic understanding of climate and the capability to predict climate and ice sheet stability on long time scales. Second, the project will help train the next generation of ice core scientists by providing the opportunity for hands-on field and core processing experience for graduate students and postdoctoral researchers. A postdoctoral researcher at the University of Washington will be directly supported by this project, and many other young scientists will interact with the project through individual science proposals. Third, the project will result in the development of a new intermediate drill which will become an important resource to US ice core science community. This drill will have a light logistical footprint which will enable a wide range of ice core projects to be carried out that are not currently feasible. Finally, although this project does not request funds for outreach activities, the project will run workshops that will encourage and enable proposals for coordinated outreach activities involving the South Pole ice core science team.
