Provision of Ice Drilling Design and Operation Group (IDDOG)

该合同支持威斯康星大学麦迪逊空间科学与工程中心的冰取芯和钻井服务（ICDS）作为新的冰取芯设计和操作小组（IDDOG），以响应NSF项目招标08-555。在完成IDDOG活动的过程中，ICDS将与新的科学钻井支持办公室（SDSO）合作，并直接响应该办公室的监督。SDSO是由一个单独的奖项（0841225）组成的，旨在为NSF资助的冰取芯和钻井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样本，这些样本在研究时可以更清楚地了解过去的气候及其变化。冰芯为古气候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将通过钻探到冰床来完成WAIS Divide冰芯项目的初始目标。IDDOG还将继续支持较小的独特钻井项目，每个项目通常与一到两个nsf资助的首席研究人员合作。ICDS拥有一套螺旋钻、钻头和取心设备，经验丰富的操作人员可以支持这类项目的工作。展望未来，IDDOG将在SDSO的指导下，根据需求和资金的确定，开发新的技术和钻井系统。可能的可能性包括：收集冰下物质样本的装置；在具有特殊古气候学意义的深度范围内采集额外冰样本的方法——最可能的方法是在主钻孔外进行偏钻，但也可能是钻一个新钻孔；一种中深度钻机，用于在流体下钻入1000米左右，以及一种或多种快速进入钻机，用于调查冰盖的基底界面、底层物质的性质，以及在浮冰的地方，调查下面的水柱和湖底或海底沉积物的特征。这项工作的更广泛的影响涉及到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的数量。WAIS Divide科学协调办公室雇用的岩芯处理人员，其中许多是从事冰芯分析项目的研究生，将继续有机会使用DISC钻头。IDDOG小项目的四名一线钻井人员中有两名是女性，预计2008-09年在WAIS division工作的钻井人员中也有两名是女性。IDDOG活动的巨大优势在于它将提供广泛的钻井设备和钻井专业知识，以支持冰川学和气候研究；例如，冰川学家期望从WAIS分水岭的深层岩芯中获得广泛的、至关重要的古气候信息。钻探工作的成果主要通过它们所支持的冰川学和气候研究来传播。钻井技术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）进行分享。ICDS的成员参与了一些外联活动，如美国国家科学基金会支持的极地嘉年华活动，他们在极地气候变化的旅行节目中通过视频和亲自露面；这种参与将继续下去。与SDSO的合作将对更广泛的影响做出另一项重大贡献，因为SDSO的主要活动之一将是加强与冰芯钻探技术相关的沟通和信息交流，以服务于冰川学界和公众。这项活动将包括建立一个共同网站，介绍当前的冰钻能力、最近活动的例子以及对未来钻井系统的详细概念描述。该网站将有组件设计，以吸引外行人以及技术页面。

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.
