The PIs propose to develop a Lagrangian Bio-acoustic Drifter system to remotely sense zooplankton in the upper ocean (100 m) and to provide real-time data via satellite telemetry. The PIs hope to integrate this technology into the Global Drifter Program - a global array of approximately 1000 drifters now operated jointly by NOAA and Scripps Institution of Oceanography. This system represents the novel convergence of three mature technologies: high-frequency bioacoustics; Lagrangian drifters; and wireless telemetry together comprise a cost-effective instrument for zooplankton remote sensing. The advance in technology proposed is a wide-band probe that sequentially samples multiple frequencies. Such a probe has been successfully developed for very high frequencies, but is costly and has limited range (5m). The probe proposed here uses precisely the same acoustic principles, has a much greater range (100 m), and lower cost. Funding of this SGER proposal will provide the proof-of-concept demonstration needed before integrating them into the drifter package. Broader ImpactsThis project will collaborate with the Hawaii Kumu Ola: Source of Knowledge Program at UH, an NSF-funded project (J Vergun, PI) aimed at increasing the number of underrepresented undergraduates (e.g. Native Hawaiians, Pacific Islanders) who earn degrees in science, technology, engineering and mathematics. This project will provide one internship to a qualified student who will participate fully in all aspects of the project. On a national and international level, the collaboration with the Global Drifter Center establishes a clear path for integrating new data products into an existing network and facility that serves oceanographic research on a global scale.

研究所提议开发一个拉格朗日生物声学漂流器系统，以遥感上层海洋（100米）的浮游动物，并通过卫星遥测提供实时数据。PI希望将这项技术整合到全球漂流者计划中-这是一个由NOAA和斯克里普斯海洋学研究所联合运营的约1000个漂流者的全球阵列。该系统代表了三种成熟技术的新颖融合：高频生物声学、拉格朗日漂移器和无线遥测，共同构成了一种成本效益高的浮游动物遥感仪器。所提出的技术进步是一种宽带探头，可以顺序采样多个频率。这种探头已经成功地开发用于非常高的频率，但是成本高并且具有有限的范围（5米）。这里提出的探头使用完全相同的声学原理，具有更大的范围（100 m）和更低的成本。这项SGER提案的资金将提供在将它们集成到漂流包之前所需的概念验证演示。更广泛的影响本项目将与夏威夷Kumu奥拉合作：在UH的知识计划的来源，一个NSF资助的项目（J Vergun，PI），旨在增加代表性不足的本科生（如夏威夷土著人，太平洋岛民）谁获得科学，技术，工程和数学学位的数量。这个项目将提供一个实习的合格学生谁将充分参与项目的各个方面。在国家和国际一级，与全球漂流者中心的合作为将新的数据产品纳入为全球范围的海洋学研究服务的现有网络和设施建立了明确的途径。
