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.

智力优势：PIs建议设计和建造一个新的移动钻井平台，用于南极冰盖。这种新的快速进入冰层钻井系统（RAID）将能够快速进入深层冰层（深度达3300米），然后对冰盖床界面和基岩基底进行取心。RAID将为跨学科研究提供一种新的工具来获得原位测量以及冰、冰川床和岩石样本。RAID将是移动的，后勤自主的，能够在几天内钻到深冰。一旦钻孔成功，就可以进行井下测井、钻取短冰和岩心以及其他取样。洞穴可以保持开放数年，以方便重新进入。该钻机正在设计中，以便每个油田季节可以完成几个井眼。一旦建成，钻井系统将作为nsf资助的设施建立。RAID将提供跨学科的能力来研究岩石圈组成、热流、冰盖动力学、过去150万年的气候历史和大气温室气体组成、古测温学、极端微生物和粒子物理学。更广泛的影响：RAID将使科学家能够解决有关南极冰盖与下面的基底之间深层界面的关键问题，并解决许多与面对气候变化的南极冰盖总体稳定性相关的未知问题。一旦开发出来，RAID将帮助训练学生进行科学的钻井作业。
