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.

PIS建议开发一种拉格朗日的生物声学漂移系统，以远程感知上海洋中的浮游动物（100 m），并通过卫星遥测提供实时数据。 PIS希望将这项技术集成到全球漂流者计划中 - NOAA和Scripps海洋学协会共同运营的大约1000个漂流者的全球阵列。该系统代表了三种成熟技术的新型融合：高频生物声学；拉格朗日漂流者；无线遥测共同组成了一种具有成本效益的工具，用于浮游遥感。提出的技术的进步是一个宽带探测器，该探测顺序采样了多个频率。这样的探针已经成功地以很高的频率开发，但是昂贵且范围有限（5m）。此处提出的探测器完全使用相同的声学原理，范围更大（100 m），成本较低。该SGER提案的资金将提供所需的概念验证演示，然后再将其集成到漂流者包中。这项项目将与.hawaii kumu ola合作进行更广泛的影响：UH的知识来源：NSF资助的项目（J Vergun，PI）旨在增加代表性不足的本科生的数量（例如，夏威夷原住民，太平洋岛屿，太平洋岛民），在科学，技术，技术，工程学和数学学业中赚取学位。该项目将为合格的学生提供一个实习，该学生将完全参与该项目的各个方面。在国家和国际层面上，与全球漂流者中心的合作建立了一条清晰的途径，将新数据产品集成到现有的网络和设施中，以在全球范围内为海洋学研究提供。
