INSPIRE Track I: Distributed Sensing Collective to Capture 3D Soundscapes

INSPIRE奖的部分资金来自计算机和信息科学与工程局计算机和网络系统部的网络物理系统计划、计算机和信息科学与工程局信息和智能系统部的信息和智能系统计划、计算机和信息科学与工程局计算机和网络系统部的计算机系统研究计划以及计算机和信息科学与工程局计算和通信基础部门的软件和硬件基础计划。声音在海洋生态系统中发挥着至关重要的作用，因为许多生物依靠声学来导航、通信、探测捕食者、以及寻找食物。因此，三维水下声景，即沉浸式水下环境中声音的组合，对于理解和保护水下生态系统具有极其重要的意义。该项目正在创建一种变革性的分布式海洋观测系统，用于研究革命性的空间(~100米)和时间(~100秒)分辨率的水下声景，该系统还能够同时分辨小规模的洋流。这些突破是通过使用配备水听器的小型海底浮标的分布式集体实现的，这些浮标利用组管理技术和传感器融合以拉格朗日方式了解海洋声景。记录声景的能力提供了一种新的传感技术，以了解声音对海洋生态系统的影响以及声音对物种发展的作用。加州圣地亚哥海岸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交织在一起的具体科学研究。海洋是全球气候的驱动因素，是一些最重要和最多样化的生态系统的家园，作为主要的食物和就业来源，海洋对世界经济做出了重大贡献。该项目的技术和科学进步为了解自然海洋资源提供了至关重要的工具，方法是研究时空尺度上的声景，而在此之前，获取声景是极其繁重和昂贵的。

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.
