An unanswered need in oceanography is to sample the ocean at higher-resolution spatial and temporal scales than presently possible. Although current systems have led tomany important discoveries, oceanographers would agree that many fundamental processes are presently unobservable due to the sparseness of the sampling geometries. Examples include the estimation of subsurface particle trajectories for ascertaining sewer effluents, the measurement of horizontal and vertical diffusivity, and the submesoscale vorticity and vertical excursions of isopycnals. These examples require versatile, quasi-Lagrangian sensors that profit fromthe same interactions generated by ocean circulation that the oceanographic ecosystemrelies on. We propose an original oceanographic observatory system based on small, inexpensive, buoyancy con- trolled drogues capable of scientific data analysis and coordinated motion control within the shear layers of the ocean circulation to monitor flows of nutrients, behaviors of animals, coastal circulation, and pol- lution dispersion.The PI's propose to developdistributed, Lagrangian sensing systems that can both track currents and sense the environment has never been approached or accomplished. The proposed ocean sampling mobile sensor network pose exciting research challenges that go well beyond any particular discipline, as they require the integration of the sensing and control aspects of the drogues with the data processing and computational analysis tailored to the specific ocean applications. Deployed over coastal areas of tens of kilometers, small armies of such drogues will concurrently map currents and sense the environment. Such vehicle swarms offer the opportunity to sample oceanic processes on space-time scales that were heretofore unobtainable while being transported at low Reynolds numbers. Since individual drogues are not tracked underwater and only relay sensed information when they are at the surface, our proposed observatory system requires minimal supporting infrastructure. With the computational tools and algorithms developed under this project, the drogues would be built at a fraction of the cost of current ocean sensor technologies.Broader ImpactsThe investigators propose outreach through high schools, community workshops, and a science festival. The investigators mention a focus on diversity. Successful development and deployment of the technology will have substantial impact of high social relevance, and the connections with the California Ocean Sciences Trust will help to ensure successful knowledge transfer. The investigators also propose a suite of other broader impacts activities, including course development and display at a local festival.

海洋学的未解决的需求是在更高分辨率的空间和时间尺度上采样海洋，而不是目前可能。尽管当前的系统已经引起了重要的发现，但海洋学家会同意，由于采样几何形状的稀疏性，目前许多基本过程目前无法观察。示例包括用于确定下水道废水的地下粒子轨迹的估计，水平和垂直扩散率的测量以及等轴心质量尺度和垂直偏移。这些示例需要多功能的准拉格朗日传感器，这些传感器从海洋生态系统所产生的相同相互作用中获利。我们提出了一种原始的海洋观测系统，基于小型，廉价，浮力控制能够进行科学数据分析和在海洋循环剪切层内进行的动作，以监视营养，沿海循环和局部探索的恐怖分子的恐怖分子，以监控养分，沿海循环和探索的范围，探索危险的环境。成就。提议的海洋采样移动传感器网络提出了令人兴奋的研究挑战，这些挑战远远超出了任何特定的学科，因为它们需要将Drogues的传感和控制方面与数据处理和计算分析相结合，并为特定的海洋应用定制。这种drogues的小型军队部署在数十公里的沿海地区，将同时绘制电流并感知环境。这种车辆群提供了机会，可以在迄今无法以低雷诺数运输的同时，以时空尺度进行采样。由于在水下没有跟踪单个drogues，并且仅在表面上传输信息，因此我们提出的天文台系统需要最少的支持基础设施。随着该项目下开发的计算工具和算法，Drogues将以当前海洋传感器技术成本的一小部分建造。Broader影响研究人员通过高中，社区讲习班和科学节提出宣传。调查人员提到了对多样性的关注。该技术的成功发展和部署将对高社会相关性产生重大影响，与加利福尼亚海洋科学信托基金会的联系将有助于确保成功的知识转移。调查人员还提出了一系列其他更广泛的影响活动，包括在当地音乐节上的课程开发和展示。
