Given human’s expanding use of the ocean, there is increasing need to understand natural and anthropogenic noise impacts to sound-sensitive taxa. Understanding acoustic ecology is vital as given rates of ocean changes and the fact that science is still unraveling how marine animals use sound to communicate, detect predators, seek prey and find suitable habitat. To gain this knowledge there is a need for a cost-effective, extended-duration tool that allows researchers to easily and experimentally replay sound cues, manipulate soundscapes and introduce ‘noise’ in field-based experiments to address new questions in ocean ecology and conservation. This effort will support the build and testing of a scalable, cost-effective, ocean-ready and long-duration sound playback tool. This tool will enable scientists to gather new insight into how sound is used by and impacts diverse marine fauna. The research will focus pilot tests on coral reefs, imperiled hubs of biodiversity that support billions of USD in ecosystem services, and seek to enhance the attraction and settlement of young corals as a method to support and potentially rebuild reefs. The project will incorporate and train undergraduate and graduate students, young technicians, and engineers, including underrepresented minorities, in all aspects of this development and testing. This effort is designed to be self-sustaining so that once it is completed, other scientists and stakeholders will be able to use acoustic enrichment and new questions to support the redevelopment of reefs and conduct previously unobtainable ecosystem studies. The science will be piloted and optimized through beta-experiments replaying soundscapes to attract coral larvae and induce settlement onto reefs. The team involved will leverage the emerging understanding of reef soundscapes, their own key data, and a beta-system, to enable this acoustically-mediated playback and larval settlement investigation tool. The technical components of the system will be durable and optimized for the playback of reef sounds, enhancing its dynamic range, sound propagation, and variety of sound patterns. The pilot tool will be tested and optimized at an established US Virgin Islands field station with years of measurements on soundscapes and community dynamics. Additional testing and user-feedback integrated will occur a new site in Year 2. From these calibrations, iterations and tests, the project will provide an important new natural-based instrument for the toolboxes of scientists and stakeholders to conduct novel acoustics studies surrounding the fields of marine ecology, changing oceans, physical oceanography, and broader basic ocean research.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.

鉴于人类对海洋的使用不断扩大，需要越来越需要了解对声音敏感分类单元的天然和人为噪音影响。理解声学生态学至关重要，因为给定海洋变化的率以及科学仍在揭示海洋动物如何使用声音进行交流，检测掠食者，寻求猎物并找到合适栖息地的事实。为了获得这些知识，需要一种具有成本效益，扩展的扩展工具，该工具使研究人员可以轻松，实验地重播声音提示，操纵音景并在基于现场的实验中引入“噪声”，以解决海洋生态学和保护中的新问题。这项工作将支持可扩展，具有成本效益，对海洋准备和长期播放的播放工具的构建和测试。该工具将使科学家能够收集有关声音如何使用和影响潜水员海洋动物区系的新见解。该研究将将试点测试重点放在珊瑚礁上，这是支持数十亿美元在生态系统服务中的生物多样性的障碍，并寻求增强年轻珊瑚的吸引力和设置，以此作为支持和潜在重建礁石的方法。该项目将在此开发和测试的各个方面纳入并培训本科生和研究生，年轻技术和工程师，包括代表性不足的少数民族。这项工作旨在自我维持，以便一旦完成，其他科学家和利益相关者将能够使用声学丰富和新问题来支持珊瑚礁的重建并进行以前无法获得的生态系统研究。该科学将通过重播音景的β示例来进行试验和优化，以吸引珊瑚幼虫并诱导礁石设置。参与的团队将利用对礁石音景，其自己的关键数据和Beta-System的新兴理解，以实现这一准确介导的播放和幼虫设置调查工具。该系统的技术组件将持久且优化，可用于礁石声音的播放，增强其动态范围，声音传播和多种声音模式。试点工具将在既定的美国维尔京群岛现场站进行测试和优化，并通过多年的音景和社区动态进行测量。其他测试和用户反馈集成的集成将在第二年发生新的网站。从这些校准，迭代和测试中，该项目将为科学家和利益相关者的工具箱提供重要的新基于天然的工具，以进行围绕海洋生态学领域的领域进行新颖的声学研究，并通过更广泛的海洋研究来进行质疑，并在NIS STAR上进行了宣传。智力优点和更广泛的影响审查标准。
