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.

1142517/Saltzman该提案请求支持一个项目，该项目旨在钻探和回收南极的新冰芯。南极冰芯将被钻探到1500米深，创造了跨度约40基尔的环境记录。该岩心将使用一种新的中间钻机进行回收，该钻机正在由美国冰钻设计与运营(IDO)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)冰芯钻探和岩心加工人员；3)数据管理；3)通过科学讲习班进行科学协调和交流。这项工作的学术价值在于，对极地冰层中稳定同位素、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和气候强迫随时间变化的大小和时间的独特信息。国际冰芯研究界阐明了在整个南极洲和格陵兰建立冰芯空间阵列的目标，从而能够重建气候多变性的区域模式，以便更深入地了解气候变化的驱动机制。该项目的更广泛影响包括获取南极冰芯将支持广泛的冰芯科学项目，这将有助于社会需要对气候有基本的了解，并有能力预测气候和冰盖在长时间尺度上的稳定性。其次，该项目将通过为研究生和博士后研究人员提供实践现场和岩心处理经验的机会，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，该项目将导致一种新的中间钻探的开发，这将成为美国冰芯科学界的重要资源。这次演习的后勤足迹将很小，这将使目前尚不可行的广泛冰芯项目得以实施。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，鼓励和支持南极冰芯科学小组参与协调外联活动的提案。
