The PI requested funding to upgrade the Passive Ocean Acoustic Waveguide Remote Sensing (POAWRS) system developed previously with NSF funding. POAWRS is a transformative approach for ocean sensing, since it is capable of monitoring sound sources over instantaneous wide areas spanning 100 km or more in diameter. In addition to marine mammal vocalizations, the other sound sources detected by POAWRS include biology such as sounds from fish and crustaceans; geophysical processes such as hurricanes and submarine volcanoes; and man-made activities such as ships and other ocean vehicles, seismic earthquake plate tectonic studies and oil exploration, as well as offshore piling. The instantaneous continental-shelf scale environmental monitoring capability and temporal-spatial dynamics of sound sources revealed by POAWRS makes it an important technology that could become an indispensable tool in field operations, such as large-scale marine ecological studies, fisheries stock assessments and management, compliance-based marine mammal as well as in studies of the effects of man-made sound on marine ecosystems. The project provides an opportunity for training and development work to a diverse team that includes both women and under-represented minorities. The principal investigator has and will continue to host and provide opportunities for K-12 students, undergraduates and teachers to learn and contribute to ocean exploration and discovery through Northeastern University's STEM Education Center, Research Experience for Teachers (RET), Young Scholars Program (YSP) and various undergraduate research opportunity programs. They have and will continue to visit elementary, middle and high schools to provide demonstrations and hands-on training in ocean discovery and sensing through ocean sounds.This project would upgrade the passive ocean acoustic waveguide remote sensing (POAWRS) array based on issues found in previous sea tests. POAWRS consists of a 160-element coherent hydrophone array system. This technology was developed for long range directional sensing, including real-time detection, bearing estimation, localization, clustering/classification and geographic mapping of ocean sound producers. The ocean entities mapped by POAWRS include vocalizing marine mammals, such as cetaceans and pinnipeds from diverse species, various soniferous fish and crustacean species, shipping and other man-made activities, as well as oceanographic and geophysical processes, such as submarine volcanoes and hurricanes. The PI will conduct mechanical upgrade of the 160-element coherent hydrophone array hardware for robust deployment and enhance and optimize POAWRS array processing and analysis software for real-time application.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.

PI要求提供资金，以升级以前由NSF资助开发的被动海洋声波波导遥感系统（POAWRS）。POAWRS是一种变革性的海洋传感方法，因为它能够在直径为100公里或更大的瞬时广域范围内监测声源。除了海洋哺乳动物的发声外，POAWRS探测到的其他声源包括鱼类和甲壳类动物发出的声音等生物;飓风和海底火山等地球物理过程;船舶和其他海洋交通工具、地震板块构造研究和石油勘探以及海上打桩等人为活动。POAWRS所显示的大陆架瞬时环境监测能力和声源的时空动态使其成为一项重要技术，可成为大规模海洋生态研究、渔业资源评估和管理、基于遵守情况的海洋哺乳动物以及研究人为声音对海洋生态系统影响等实地作业中不可或缺的工具。该项目为包括妇女和代表性不足的少数群体在内的多元化团队提供了培训和发展工作的机会。首席研究员已经并将继续主持并为K-12学生，本科生和教师提供机会，通过东北大学的STEM教育中心，教师研究经验（RET），青年学者计划（YSP）和各种本科生研究机会计划来学习和促进海洋探索和发现。他们已经并将继续访问小学、初中和高中，提供通过海洋声音发现和感知海洋的演示和实践培训，该项目将根据以往海上试验中发现的问题升级被动海洋声波波导遥感阵列。POAWRS由160单元相干水听器阵列系统组成。这项技术是为远程定向传感而开发的，包括实时检测、方位估计、定位、聚类/分类和海洋声音产生者的地理测绘。POAWRS绘制的海洋实体包括发出声音的海洋哺乳动物，如不同物种的鲸目动物和鳍足动物、各种传声鱼类和甲壳类物种、航运和其他人为活动，以及海洋学和地球物理过程，如海底火山和飓风。PI将对160单元相干水听器阵列硬件进行机械升级，以实现稳健部署，并增强和优化POAWRS阵列处理和分析软件，以实现实时应用。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
