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.

pi建议开发拉格朗日生物声学漂流器系统，以远程感知海洋上层（100米）的浮游动物，并通过卫星遥测提供实时数据。ppi希望将这项技术整合到全球漂流计划中，该计划目前由美国国家海洋和大气管理局和斯克里普斯海洋研究所共同运营，拥有大约1000艘漂流船。该系统代表了三种成熟技术的新颖融合：高频生物声学；拉格朗日漂流者;和无线遥测技术一起构成了一种具有成本效益的浮游动物遥感仪器。提出的技术进步是一种宽频带探针，可以对多个频率进行顺序采样。这种探头已经成功地开发了非常高的频率，但价格昂贵且范围有限（5米）。这里提出的探针使用完全相同的声学原理，具有更大的范围（100米），成本更低。该SGER提案的资金将提供在将其纳入漂流器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 Ola：知识之源计划在UH，一个nsf资助的项目（J Vergun， PI），旨在增加未被充分代表的本科生（如夏威夷原住民，太平洋岛民）谁获得科学，技术，工程和数学学位的人数。该项目将为合格的学生提供一次实习机会，该学生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现有的网络和设施建立了一条明确的道路，为全球范围的海洋学研究提供服务。
