The Arctic is home to some four million people comprising a diverse range of cultures and an economy worth about $230 billion annually. With global concerns spanning climate change, energy resources, freshwater supplies, and sustainable economic growth, the Arctic has sparked intense research and public interest. International efforts to establish sustained Arctic observing systems, especially for long-term Arctic Ocean monitoring with near-real-time data transfer, are urgently needed. The harsh and remote conditions constraining year-round observation sites present significant logistical challenges and energy needs for sustained Arctic observations. In addition, monitoring of the Arctic Ocean using bottom-anchored stationary platforms is limited by a lack of real-time communication between the sensors deployed and Arctic operators. The ultimate goal of this project is to develop new energy harvesting and communication solutions so that it is feasible to have a real-time under-ice monitoring system in the Arctic Ocean. This EAGER project tests the capacity to address three key challenges, including sustainable power supply through energy harvesting, near-real-time data communication under the sea ice, and survivability under harsh environmental conditions. Specifically, the project aims to develop novel techniques to harvest ultra-low-speed oceanic current energy using a two-level diffuser augmented turbine and a novel transverse flux generator. The harvested energy will be used to support sensors and power a novel real-time communication system through the sea ice. The proposed communication system adopts a novel antenna design that overcomes seawater attenuation effects on radio waves and creatively leverages satellite protocols to ensure the under-ice communication unit can transmit observational data to satellites. The project also explores techniques to enhance the survivability of the under-ice monitoring system, such as robust material choice and ice ridge/keel detection and avoidance systems and extends science and engineering education among K-12 and PhD-level students in Arctic research with an emphasis on diversity including female and underrepresented students.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

北极是约400万人的所在地，包括各种各样的文化和每年价值约2300亿美元的经济体。由于全球担忧涵盖了气候变化，能源，淡水供应和可持续的经济增长，北极引发了强烈的研究和公共利益。迫切需要国际北极观察系统的努力，尤其是对于长期的北极海洋监测，并急需近实时的数据传输。限制全年观察地点的严峻和遥远条件提出了持续的北极观察的重大后勤挑战和能量需求。此外，使用底部固定的固定平台对北极海洋进行监测受到部署和北极操作员之间缺乏实时通信的限制。该项目的最终目的是开发新的能源收集和通信解决方案，以便在北极海洋中具有实时的冰底漆监测系统是可行的。该急切的项目测试了应对三个主要挑战的能力，包括通过能源收集，海冰下的近实时数据通信以及在恶劣的环境条件下的生存能力。具体而言，该项目旨在使用两级扩散器增强涡轮机和新型的横向通量发生器来开发新技术来收集超低速度的海洋电流能量。收获的能量将用于支持传感器并通过海冰为新颖的实时通信系统供电。提出的通信系统采用了一种新型的天线设计，该设计克服了对无线电波的海水衰减影响，并创造性地利用了卫星协议，以确保冰底盘通信单元可以将观测数据传输到卫星。该项目还探讨了增强冰冰监测系统的生存能力的技术，例如健壮的材料选择，冰脊/龙骨/龙骨检测和回避系统，并通过北极研究中的K-12和PhD级学生扩展科学和工程教育。该奖项反映了NSF的法定任务，重点是包括女性和代表性不足的学生，并被认为是值得通过基金会的知识分子优点和更广泛影响的评论标准来评估的。
