Collaborative Research: Phase 2 Development of A Rapid Access Ice Drilling (RAID) Platform for Research in Antarctica

PI将设计和建造一个新的快速访问冰钻（RAID）用于南极洲。该钻机将有能力快速钻透3300米厚的冰，然后收集冰、冰盖床界面和下面基岩基底的样本。这种钻探技术将为地质学、冰川学、古气候学、微生物学和天体物理学的跨学科研究提供一种获得原位测量和样品的新方法。RAID钻井平台将使科学界能够获得各种时间尺度上的地质和气候变化记录，从十亿年的岩石记录到千年的冰和气候历史。RAID系统的成功开发将提供一个目前尚不具备的研究工具。该平台的开发将使科学家能够解决有关南极冰盖与其下基底之间深层界面的关键问题。RAID的发展将提供一种方法，以解决许多与南极冰盖在面对气候变化和海平面上升的总体稳定性相关的未知数。RAID的科学原理在以前的提案（Goodge 1242027）中进行了审查。私人侦探被批准了？第一阶段？此外，我们还将提供资金，为RAID钻机制定更详细的概念设计，以便在RAID建成后更好地了解其建造成本以及运营和维护成本。第一阶段的支持还允许PI与研究界合作，为演习制定更详细的科学要求。该提案要求继续提供资金（第二阶段），以建造、组装和测试RAID钻井平台，直至在南极进行未来的科学作业。

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.
