The PIs will design and build a new rapid access ice drill (RAID) for use in Antarctica. This drill will have the ability to rapidly drill through ice up to 3300 m thick and then collect samples of the ice, ice-sheet bed interface, and bedrock substrate below. This drilling technology will provide a new way to obtain in situ measurements and samples for interdisciplinary studies in geology, glaciology, paleoclimatology, microbiology, and astrophysics. The RAID drilling platform will give the scientific community access to records of geologic and climatic change on a variety of timescales, from the billion-year rock record to thousand-year ice and climate histories. Successful development of the RAID system will provide a research tool that is currently unavailable. Development of this platform will enable scientists to address critical questions about the deep interface between the Antarctic ice sheets and the substrate below. Development of RAID will provide a way to address many of the unknowns associated with general stability of the Antarctic ice sheets in the face of changing climate and sea level rise.The scientific rationale for RAID was reviewed in a previous proposal (Goodge 1242027). The PIs were granted ?Phase I? funding to develop a more detailed conceptual design for the RAID drill that would provide a better understanding of construction costs as well as operation and maintenance costs for RAID once it is constructed. Phase I support also allowed the PIs to work with the research community to develop more detailed science requirements for the drill. This proposal requests continued funding (Phase II) to construct, assemble and test the RAID drilling platform, through to staging it in Antarctic for future scientific operations.

PI将设计并建造一个新的快速访问冰钻（RAID），用于在南极洲使用。该钻头将能够快速钻探最大3300 m厚的冰，然后收集下面的冰，冰床界面和基岩基板的样品。这种钻探技术将为获得地质，冰川学，古气候学，微生物学和天体物理学的跨学科研究的原位测量和样本提供一种新的方法。 RAID钻井平台将使科学界访问从数十亿年的岩石记录到千年的冰和气候历史的各种时间尺度上的地质和气候变化记录。突袭系统的成功开发将提供目前无法使用的研究工具。该平台的开发将使科学家能够解决有关南极冰盖和下面基板之间深层接口的关键问题。 RAID的发展将提供一种解决与气候变化和海平面上升的南极冰盖一般稳定性相关的许多未知数的方法。 PI被授予？第一阶段？为RAID演习开发更详细的概念设计的资金，该设计将更好地理解建筑成本，以及一旦RAID的构建，可以为其进行操作和维护成本。第一阶段的支持还允许PI与研究界合作，为演习开发了更详细的科学要求。该提案要求继续资金（第二阶段）构建，组装和测试RAID钻井平台，以在南极进行未来的科学操作，以进行攻击钻井平台。
