Bentley/0841135This award supports the University of Wisconsin - Madison Space Science and Engineering Center's Ice Coring and Drilling Services (ICDS) to act as the new Ice Drilling Design and Operations Group (IDDOG) in response to NSF Program Solicitation 08-555. In fulfilling its IDDOG activities, ICDS will work with and directly respond to oversight from the new Scientific Drilling Support Office (SDSO), which is being formed by a separate award (0841225) to provide scientific leadership and oversight of ice coring and drilling activities funded by NSF. IDDOG drilling activities enable scientists to obtain samples of ice from polar ice sheets and mountain glaciers throughout the world which, when studied, result in a clearer understanding of past climate and its variations. Ice cores provide the most comprehensive datasets available for paleoclimatological research and the intellectual merit of IDDOG activities resides in enabling this research to take place. In the next five years IDDOG will complete the initial objectives of the WAIS Divide Ice Core Project by drilling to the bed. IDDOG will also continue supporting smaller unique drilling projects, each usually in association with one or two NSF-funded Principal Investigators. ICDS maintains a suite of augers, drills, and coring equipment with experienced operators to support this type of project work. Looking to the future, IDDOG will work under the direction of the SDSO to develop new techniques and drilling systems as the need arises and funding is identified. Likely possibilities include: devices for collecting samples of the subglacial material; methods to take additional samples of ice through depth ranges of particular paleoclimatological interest -- most likely by deviation drilling off the main borehole, but possibly by drilling a new hole; an intermediate-depth drill for drilling to the order of 1000 m under a fluid, and one or more types of rapid access drills, for investigating the basal interface of ice sheets, the nature of the underlying material, and, where the ice is afloat, the characteristics of the water column and lake- or ocean-bottom sediments below. The broader impacts of this work relate to the personnel who will be involved in this effort. During the WAIS Divide project IDDOG will attempt to recruit several new people each season to expand the pool of trained drillers. Core handlers hired by the WAIS Divide Science Coordination Office, many of whom are graduate students working on ice core analysis projects, will continue to be given opportunities to work with the DISC drill. Two of the four IDDOG front-line drillers for the small projects are women, as are two of the drillers expected to work at WAIS Divide in 2008-09. The great strength of the IDDOG activity resides in the extensive drilling equipment and drilling expertise it will supply in support of glaciological and climatic research; for example, glaciologists expect extensive, critically important paleoclimatic information to come from the WAIS Divide deep core. The results of the drilling work are disseminated principally through the glaciological and climatic research they support. Drilling technology is shared through occasional international workshops and regularly through personal contacts, including international exchange of personnel. Members of ICDS have participated in outreach activities such as the NSF-supported Polar Palooza program through appearance in videos and in person as part of their traveling show on polar climate change; such participation will continue. Another major contribution to broader impacts will arise in collaboration with the SDSO, since one of the SDSO's primary activities will be to enhance communication and information exchange related to ice core drilling technology as a service to the glaciological community and the general public. This activity will include the implementation of a common website that describes current ice drilling capabilities, with examples of recent activities, as well as detailed conceptual descriptions of future drilling systems. The website will have components designed to be attractive to laypeople as well as technical pages.

Bentley/0841135该奖项支持威斯康星州-麦迪逊空间科学与工程中心的冰取芯和钻探服务（ICDS）作为新的冰钻探设计和运营组（IDDOG），以响应NSF计划征集08-555。在完成其IDDOG活动时，ICDS将与新的科学钻探支持办公室（SDSO）合作并直接回应其监督，该办公室由一个单独的奖项（0841225）组成，为NSF资助的冰取芯和钻探活动提供科学领导和监督。IDDOG钻探活动使科学家能够从世界各地的极地冰盖和山地冰川中获取冰的样本，通过研究，可以更清楚地了解过去的气候及其变化。 冰芯为古气候学研究提供了最全面的数据集，IDDOG活动的智力价值在于使这项研究得以进行。 在接下来的五年里，IDDOG将通过钻到海床来完成WAIS分水岭冰芯项目的最初目标。 IDDOG还将继续支持较小的独特钻井项目，每个项目通常与一名或两名NSF资助的首席调查员有关。 ICDS拥有一套螺旋钻、钻机和取芯设备，并配备有经验丰富的操作人员，以支持此类项目工作。展望未来，IDDOG将在SDSO的指导下工作，根据需要和资金的确定开发新的技术和钻井系统。可能的可能性包括：收集冰下物质样品的装置;在具有特殊古气候意义的深度范围内采集额外冰样品的方法-最有可能是在主钻孔外进行偏钻，但也可能是钻一个新的钻孔;用于在流体下钻探到1000米量级的中深度钻机，以及一种或多种类型的快速进入钻机，用于调查冰盖的基底界面、底层物质的性质，以及在冰漂浮的地方，水柱和下面的湖底或海底沉积物的特征。这项工作的更广泛影响涉及将参与这项工作的人员。 在WAIS Divide项目期间，IDDOG将尝试在每个季度招募几名新人，以扩大训练有素的钻井人员库。WAIS Divide科学协调办公室聘请的岩芯处理人员中，许多是从事冰芯分析项目的研究生，他们将继续有机会与DISC钻机一起工作。IDDOG小型项目的四名一线钻井工中有两名是妇女，预计2008- 2009年在WAIS Divide工作的两名钻井工也是妇女。IDDOG活动的巨大优势在于它将提供广泛的钻探设备和钻探专业知识，以支持冰川学和气候研究;例如，冰川学家希望从WAIS分水岭深芯获得广泛的、至关重要的古气候信息。钻探工作的结果主要通过其支持的冰川学和气候研究传播。通过偶尔的国际研讨会和定期的个人接触，包括国际人员交流，分享钻井技术。ICDS的成员参加了一些外展活动，如NSF支持的Polar Palooza计划，他们通过视频和亲自参加极地气候变化巡回演出;这种参与将继续下去。对更广泛影响的另一个重大贡献将通过与SDSO的合作产生，因为SDSO的主要活动之一将是加强与冰芯钻探技术有关的沟通和信息交流，作为对冰川学界和公众的服务。这项活动将包括建立一个共同网站，介绍目前的钻冰能力，并举例说明最近的活动，以及对未来钻冰系统的详细概念说明。该网站将有组件设计，以吸引外行以及技术网页。
