Wave Gliders in the Development of a Continental-Scale Integrated Ocean-Observing System

该项目要求拨款测试一种无人驾驶飞行器——液体机器人公司（LRI）波浪滑翔机的可行性，该飞行器可以运行加州海洋渔业合作调查（CALCOFI）项目中发现的标准海洋测量线。波浪滑翔机将使目前在CALCOFI巡航上执行的正在进行的观测标准集。通过提供一种更具成本效益的方法来收集这些类型的数据，波浪滑翔机可以成为大陆尺度综合海洋观测系统的组成部分。研究工作的一个主要部分是开发一种科学质量的回声测深仪，该测深仪具有适当的多频能力、数据存储、有效载荷特性以及与Wave Glider成功集成所需的低功耗。除了拟议的用途之外，这种回声探测仪还将支持生物声学海洋学和渔业声学中的其他应用，这些应用利用了无人驾驶车辆和拉格朗日平台（例如，漂流者，浮子和滑翔机）的科学和经济效益。更广泛的影响：波浪滑翔机似乎是一个创新的回声探测仪平台，因为它停留在水面上，有连续的卫星GPS和数据遥测，还有太阳能充电的潜力。这种平台上的回声探测能力将是生物/渔业研究和管理的重大进步。想象一下，增加甚至取代目前用于渔业调查的昂贵的船舶作业，使用具有成本效益的滑翔机船队，可以提供更好的空间和时间覆盖。除了开发和演示可能最终在海洋科学界获得广泛应用的新采样技术外，拟议的活动还将提供实验数据来支持至少一篇博士论文，并将为至少一名工程硕士候选人提供先进的仪器开发经验。PI已经确定了一名特定的博士生和一名尚未确定的工程硕士学生，他们将被支持作为研究生研究助理；没有具体提到扩大代表性不足群体参与的努力。

The PI requests funding to test the feasibility of instrumenting an unmanned vehicle, the Liquid Robotics Incorporated (LRI) Wave Glider, to run standard oceanographic lines like those found in the California Cooperative Oceanic Fisheries Investigations (CALCOFI) program. It is intended that Wave Gliders will make the standard set of underway observations currently performed on CALCOFI cruises. By providing a more cost-effective approach to collecting these types of data, Wave Gliders can become integral components of a continental-scale, integrated ocean-observing system. A major part of the proposed research effort involves the development of a scientific quality echo sounder with the appropriate multi-frequency capability, data storage, payload characteristics, and low-power consumption required for successful integration with the Wave Glider. In addition to the proposed use such an echo sounder will support other applications in bioacoustical oceanography and fisheries acoustics that take advantage of the scientific and economical benefits of unmanned vehicles and Lagrangian platforms (e.g., drifters, floats, and gliders). Broader Impacts: The wave glider seems like an innovative platform for an echo-sounder because it stays on the surface, has continuous satellite GPS and data telemetry, and the potential for solar charging. An echo-sounding capability on such a platform would be a significant advancement for biological/fisheries research and management. Imagine the benefit of augmenting or even replacing expensive ship operations that currently run echo-sounder transects for fisheries surveys with a fleet of cost efficient gliders that could provide better spatial and temporal coverage. In addition to the development and demonstration of a new sampling technology that may ultimately gain broad utility within the ocean science community the proposed activity will also provide experimental data to support at least one doctoral dissertation and will provide advanced instrumentation development experience to at least one Master of Engineering candidate. The PI has identified a specific doctoral student and an as-yet-undetermined Master of Engineering student who would be supported as graduate research assistants; there is no specific mention of efforts to broaden participation of underrepresented groups.
