This INSPIRE award is partially funded by the Cyber-Physical Systems Program in the Division of Computer and Network Systems in the Directorate for Computer and Information Science and Engineering, the Information and Intelligent Systems Program in the Division of Information and Intelligent Systems in the Directorate for Computer and Information Science and Engineering, the Computer Systems Research Program in the Division of Computer and Network Systems in the Directorate for Computer and Information Science and Engineering, and the Software and Hardware Foundations Program in the Division of Computing and Communications Foundations in the Directorate for Computer and Information Science and Engineering.Sound plays a vital role in the ocean ecosystem as many organisms rely on acoustics for navigation, communication, detecting predators, and finding food. Therefore, the 3D underwater soundscape, i.e., the combination of sounds present in the immersive underwater environment, is of extreme importance to understand and protect underwater ecosystems. This project is creating a transformative distributed ocean observing system for studying the underwater soundscape at revolutionary spatial (~100 meters) and temporal (~100 seconds) resolutions that is also able to simultaneously resolve small-scale ocean current flow. These breakthroughs are achieved using a distributed collective of small hydrophone-equipped subsurface floats, which utilize group management techniques and sensor fusion to understand the ocean soundscape in a Lagrangian manner. The ability to record soundscapes provides a novel sensing technology to understand the effects of sound on marine ecosystems and the role that sound plays for species development. Experiments off the coast of San Diego, CA, and a research campaign in the Cayman Islands provide concrete scientific studies that are tightly interwoven with the engineering research.Oceans are drivers of global climate, are home to some of the most important and diverse ecosystems, and represent a substantial contribution to the world's economy as a major source of food and employment. The technological and scientific advances in this project provide crucial tools to understand natural ocean resources, by studying soundscapes at spatio-temporal scales that were heretofore extremely burdensome and expensive to obtain.

该INSPIRE奖是由计算机和信息科学和工程局的计算机和网络系统部的网络物理系统计划部分资助的计算机和信息科学和工程局。声音在海洋生态系统中起着至关重要的作用，因为许多生物都依靠声学来进行导航，交流，检测捕食者和寻找食物。因此，3D水下音景，即身临其境的水下环境中存在的声音的组合对于理解和保护水下生态系统至关重要。该项目正在创建一个变革性的分布式海洋观察系统，用于研究革命空间（〜100米）和时间（〜100秒）的水下音景，也能够同时解决小规模的海洋电流流量。这些突破是使用配备小型水力音的地下浮子的分布式集体来实现的，该集合利用小组管理技术和传感器融合以拉格朗日的方式理解海洋音景。记录音景的能力为了解声音对海洋生态系统的影响以及声音在物种发展中的作用提供了一种新颖的传感技术。在加利福尼亚州圣地亚哥海岸附近的实验和开曼群岛的一项研究活动提供了与工程研究紧密相互交织的具体科学研究。医生是全球气候的驱动因素，是一些最重要，最多样化的生态系统的所在地，并代表了世界上对世界经济的重要贡献，作为食品和食品的主要来源。该项目的技术和科学进步提供了重要的工具来了解自然海洋资源，通过在时髦的时空尺度上研究声景，这些尺度迄今为止非常繁重且昂贵。
