Title: Rapid Access Ice Drill (RAID) Science WorkshopNon-technical SummaryThis workshop will support members of the Geological, Glaciological, and Earth Science communities for a two-day workshop in order to develop a long-term plan for science deployment of the Rapid Access Ice Drill (RAID) platform and create a planning document that defines the science community?s anticipated use of the facility. The workshop will ensure broad participation by including researchers from many different scientific fields both within and outside of the Antarctic community. The workshop will Include early-career researchers and members of underrepresented groups. Technical DescriptionThe Rapid Access Ice Drill (RAID) was designed to quickly penetrate Antarctic ice sheets in order to create borehole observatories and take cores in deep ice, the glacial bed, and bedrock below. The Rapid Access Ice Drill is a sled-mounted mobile drilling system that will make multiple long, narrow (3.5 inch diameter) boreholes in ice sheets of Antarctica. The Rapid Access Ice Drill (RAID) enabled research will include 1) a better understanding of the climate feedbacks internal to the Earth System that drove ice ages to switch from a 41-kyr periodicity to the irregular 110-kyr periodicity seen today, 2) constraints on future sea level rise from the heat flow and bed material property information obtained, 3) creation of a new interdisciplinary style of Antarctic "Subglacial System Science" that fosters across-discipline synergies, and 4) entrainment of young researchers in polar science via the excitement of discovery of the largely unknown ice sheet interior. The RAID Science Planning Workshop will provide a venue to: 1) bring diverse scientists together to explore science questions and approaches; 2) define science goals to be addressed by the drill; 3) seek synergies between different disciplines interested in the Rapid Access; 4) develop a coherent science plan for the use of the drill; 5) set priorities between the science targets; and 6) engage early-career and underrepresented researchers. The workshop will provide support for a two-day conference with a total attendance of about 60 members of the Antarctic glacial- and subglacial-science communities. The support provided by NSF will cover partial travel costs for 20 key US participants and full travel costs for 12 early-career researchers.

该研讨会将为地质、冰川学和地球科学界的成员提供为期两天的研讨会，以制定快速进入冰钻（RAID）平台的科学部署的长期计划，并创建一个定义科学界的规划文件。该设施的预期用途。讲习班将确保包括来自南极共同体内外许多不同科学领域的研究人员的广泛参与。研讨会将包括早期职业研究人员和代表性不足的群体的成员。技术描述快速进入冰钻（RAID）的设计目的是快速穿透南极冰盖，以便建立钻孔观测站，并在深冰、冰川床和基岩中获取岩心。快速通道冰钻是一个安装在雪橇上的移动钻井系统，它将在南极洲的冰盖上钻出多个又长又窄（直径3.5英寸）的钻孔。快速访问冰钻（RAID）支持的研究将包括：1)更好地理解地球系统内部的气候反馈，这些反馈驱动冰河时代从41千年历周期转变为今天看到的不规则的110千年历周期；2)从获得的热流和床物质属性信息中对未来海平面上升的限制；3)创造一种新的跨学科风格的南极“冰下系统科学”，促进跨学科的协同作用。4)发现未知的冰盖内部所带来的兴奋，使年轻的研究人员对极地科学产生兴趣。RAID科学规划研讨会将提供一个场所：1)将不同的科学家聚集在一起探索科学问题和方法；2)明确训练要实现的科学目标；3)在对快速检索感兴趣的不同学科之间寻求协同效应；4)为钻头的使用制定连贯的科学计划；5)确定科学目标之间的优先级；6)参与早期职业和代表性不足的研究人员。该研讨会将为一个为期两天的会议提供支持，该会议共有大约60名来自南极冰川和冰川下科学界的成员参加。美国国家科学基金会提供的支持将包括20名美国主要参与者的部分旅费和12名早期职业研究人员的全部旅费。
