Intellectual Merit: The PIs propose to design and build a new mobile drilling platform for use on Antarctic ice sheets. This new Rapid Access Ice Drilling system (RAID) will enable rapid access to deep ice (up to 3300 m depth), followed by coring of the ice-sheet bed interface and bedrock substrate below. RAID will provide a new tool to obtain in situ measurements as well as samples of ice, glacial bed, and rock for interdisciplinary studies. RAID will be mobile, logistically autonomous, and capable of drilling to deep ice within a few days. Once a borehole is created, down-hole logging, drilling of short ice and rock cores, and other sampling can follow. Holes can be kept open for several years to facilitate re-entry. The drill is being designed so that several holes may be completed per field season. Once built, the drilling system will be established as an NSF-sponsored facility. RAID will provide an interdisciplinary capability to study lithospheric composition, heat flow, ice-sheet dynamics, climate history and atmospheric greenhouse gas composition over the past 1.5 million years, paleothermometry, extremophile organisms, and particle physics.Broader impacts: RAID will enable scientists to address critical questions about the deep interface between the Antarctic ice sheets and the substrate below and address many of the unknowns associated with general stability of the Antarctic ice sheets in the face of changing climate. Once developed, RAID will help train students in scientific drilling operations.

知识分子优点：PIS建议设计和建立一个新的移动钻井平台，用于在南极冰盖上。这种新的快速进入冰钻系统（RAID）将使深层冰（深度最高3300 m）能够快速进入，然后在下面的冰床界面和基岩基板上加油。 RAID将提供一种新工具，以获得原位测量以及用于跨学科研究的冰，冰川床和岩石样品。 RAID将是移动的，具有逻辑性的自动性，并且能够在几天内钻入深层冰。一旦创建了钻孔，就可以随后钻孔，对短冰和岩石的钻孔以及其他采样。孔可以保持几年以促进重新进入。正在设计演习，以便每个野外季节可以完成几个孔。建造后，将建立钻井系统作为NSF赞助的设施。 RAID将提供跨学科的能力，以研究岩石圈组成，热流，冰原动态，气候历史和大气温室气体成分在过去150万年中，苍白的热度学，极端的有机体和粒子物理学。突袭者：RAID能够使科学家能够解决有关与众不同的重要界面，以解决与众不同的界面，并在许多界面之间进行互联网和界面之间的关键问题，并在许多界面之间进行了与众不同的界面和互联网之间的界面和界面。面对气候变化的南极冰盖。一旦开发，RAID将帮助培训学生进行科学钻探操作。
