RII Track-1: Ike Wai: Securing Hawaii's Water Future

非技术性描述这个项目名为Ike阿威，来自夏威夷语，意思是知识和水，将解决该州维持清洁水供应的关键需求，其中大部分来自地下水源。这种供应受到人口增长、经济发展和气候变化的压力越来越大。水资源的有效管理需要详细了解地下地质特征，这些特征决定了地下水的流动路径;由于其火山起源和历史，这些特征在夏威夷特别复杂。这个项目将大大提高了解哪里的水，提供了夏威夷的需要？美国的城市、农场和工业来自哪里，以及如何确保持续、高质量的供应。项目小组将与关注水资源管理的联邦、州和地方机构以及社区团体进行接触和合作。培训和教育计划将准备一个多样化的劳动力能够满足未来的研究和决策的挑战。技术说明这个项目的首要科学目标是产生更准确和详细的模型夏威夷？的含水层，水流和运输过程。地球物理成像将用于生成地下地质结构的高分辨率3D地图。将通过水井监测、地球化学和海底地下水排放分析以及使用微生物多样性作为新型地下水示踪剂来测量含水层的体积、流量和连通性。该项目还将建立综合知识环境，这是一个集中的网络基础设施平台，用于数据存储，高性能计算，数值建模和可视化。这一资源将包括来自项目的数据以及来自政府机构合作者的遗留和新数据，并将作为研究和水管理决策支持的工具。通过该项目获得的建模工具和知识将扩展到其他火山太平洋岛屿。该项目将为本科生、研究生和博士后提供物理学、水文学和数据科学方面的培训，并为这些群体和初级教师提供职业发展指导。重点将放在征聘和留住妇女和任职人数不足的少数民族，特别是夏威夷土著人和太平洋岛民。

Non-technical DescriptionThis project, titled Ike Wai from the Hawaiian words for knowledge and water, will address the critical needs of the state to maintain its supply of clean water, most of which comes from groundwater sources. This supply is under increasing pressures from population growth, economic development, and climate change. Effective management of water resources requires detailed understanding of the underground geologic features that determine the flow paths of subsurface water; these features are particularly complex in Hawaii due to its volcanic origins and history. This project will greatly improve understanding of where the water that provides for the needs of Hawaii?s cities, farms, and industries comes from and how to ensure a continued, high quality supply. The project team will engage and collaborate with federal, state, and local agencies and community groups concerned with water management. Training and education initiatives will prepare a diverse workforce capable of meeting the research and policy-making challenges of the future.Technical Description The overarching scientific goal of this project is to generate more accurate and detailed models of Hawaii?s aquifers, water flow, and transport processes. Geophysical imaging will be used to produce high-resolution 3D maps of subsurface geologic structures. Aquifer volume, flow, and connectivity will be measured by well monitoring, geochemical and submarine groundwater discharge analyses, and the use of microbial diversity as a novel groundwater tracer. The project will also establish the Integrated Knowledge Environment, a centralized cyberinfrastructure platform for data storage, high performance computation, numerical modeling, and visualization. This resource will include data from the project as well as legacy and new data from governmental agency collaborators, and will serve as a tool for both research and water management decision support. The modeling tools and knowledge gained through this project will be extensible to other volcanic Pacific islands. The project will provide training in geophysics, hydrology, and data science to undergraduates, graduate students, and postdocs, and also provide career development mentoring to these groups and junior faculty. Emphasis will be placed on the recruitment and retention of women and under-represented minorities, particularly Native Hawaiian and Pacific Islanders.
