This award provides support for "EAGER: Handbook of Hot Water Drill System (HWDS) Design Considerations and Best Practices" from the Antarctic Integrated System Science within the Office of Polar Programs. More and more science projects are proposing to use hot-water drilling systems (HWDS) to rapidly and/or cleanly access glacial and subglacial systems. To date the hot-water drill systems have been developed in isolation, and no attempt has been made to gather information about the different systems in one place. This proposal requests funds to document existing HWDS, and to then assess the design, testing, and development of a hot-water drill system that will be integrated with the evolving over-ice traverse capability of the USAP program.Intellectual Merit: A working handbook of best practices for hot-water drill design systems, including safety considerations, is long overdue, and will 1) provide suggestions for optimizing current systems; 2) contribute in the very near term to already funded projects such as WISSARD (Whillans Ice Stream Subglacial Access and Research Drilling); and 3) fit the long-term needs of the Antarctic science community who have identified rapid and clean access to glacial and subglaical environments as a top priority for the next decades. The collected information will be used for community education and training, will discuss potential design and operational trade-offs, and will identify ways to optimize the capabilities of an integrated USAP traverse and HWDS infrastructure. EAGER funding for this project is warranted because such a handbook has not been tried before, and needs to be shown to be doable prior to larger investments in such compilations. It fits the AISS (Antarctic Integrated System Science) program as an optimized HWDS will meet the needs of many different Antarctic research disciplines including biology, geology, glaciology, and oceanography.Broader Impacts: The proposed work is being done on behalf of the Antarctic research community, and will seek to capture the knowledge of experienced hot-water drill engineers who are nearing retirement, and to educate the next generation of hot-water drillers and engineers. The PI indicates he will work with the owners of such systems both within the US and abroad. Identification of best practices in hot-water drilling will save several different Antarctic research communities significant time, effort, and funding in the future.

该奖项为极地计划办公室南极综合系统科学的“EAGER：热水钻井系统（HWDS）设计考虑和最佳实践手册”提供支持。越来越多的科学项目建议使用热水钻井系统（HWDS）来快速和/或清洁地进入冰川和冰下系统。迄今为止，热水钻系统是孤立开发的，没有试图在一个地方收集有关不同系统的信息。该提案要求提供资金，以记录现有的HWDS，然后评估热水钻系统的设计、测试和开发，该热水钻系统将与USAP计划不断发展的冰上穿越能力相结合。2）在短期内为已经资助的项目做出贡献，如WISSARD（Whillans Ice Stream Subglacial Access and Research Drilling）; 3）满足南极科学界的长期需求，他们已将快速和清洁地进入冰川和亚冰川环境确定为未来几十年的首要任务。收集的信息将用于社区教育和培训，将讨论潜在的设计和操作权衡，并将确定优化集成USAP遍历和HWDS基础设施的能力的方法。EAGER对该项目的资助是有道理的，因为以前没有尝试过这样的手册，需要在对这种汇编进行更大投资之前证明是可行的。它符合AISS（南极综合系统科学）计划作为一个优化的HWDS将满足许多不同的南极研究学科的需求，包括生物学，地质学，冰川学和海洋学。这项拟议中的工作是代表南极研究界进行的，并将寻求获得即将退休的经验丰富的热水钻井工程师的知识，并教育下一代热水钻探者和工程师。PI表示，他将与美国和国外的此类系统的所有者合作。确定热水钻探的最佳实践将在未来为几个不同的南极研究团体节省大量的时间、精力和资金。
