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.

标题：快速冰钻 (RAID) 科学研讨会非技术摘要本研讨会将为地质、冰川和地球科学界的成员提供为期两天的研讨会支持，以便制定快速冰钻科学部署的长期计划Ice Drill (RAID) 平台并创建一份规划文件，定义科学界对该设施的预期使用。该研讨会将确保来自南极界内外许多不同科学领域的研究人员的广泛参与。该研讨会将包括早期职业研究人员和代表性不足群体的成员。技术描述快速冰钻 (RAID) 旨在快速穿透南极冰盖，以便建立钻孔观测站并在深冰、冰川床和下面的基岩中获取岩芯。快速冰钻机是一种安装在雪橇上的移动钻孔系统，可在南极洲的冰盖上打出多个又长又窄（直径 3.5 英寸）的钻孔。快速冰钻 (RAID) 启用的研究将包括 1) 更好地了解地球系统内部的气候反馈，这些反馈推动冰河时代从 41 kyr 周期转变为今天看到的不规则 110 kyr 周期，2)根据获得的热流和床层物质特性信息对未来海平面上升的限制，3）创建南极“冰下系统科学”的新跨学科风格，促进跨学科协同作用，以及4) 通过发现很大程度上未知的冰盖内部的兴奋感，吸引年轻的研究人员参与极地科学。 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) 定义演习要解决的科学目标； 3）寻求对快速访问感兴趣的不同学科之间的协同作用； 4）为演练的使用制定连贯的科学计划； 5）设定科学目标之间的优先顺序； 6) 吸引处于职业生涯早期且代表性不足的研究人员。 该研讨会将为为期两天的会议提供支持，共有约 60 名南极冰川和冰下科学界成员出席。 NSF 提供的支持将支付 20 名美国主要参与者的部分旅行费用和 12 名早期职业研究人员的全额旅行费用。
