"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."The PIs request funding to develop the next generation of mini-floats for in situ measurement of currents and environmental variables (fluorescence, temperature, PAR). The principal objective of these mini-floats is to sample oceanic processes at high temporal resolution (minutes) with concurrent spatial resolution of 10's of meters. To accomplish this goal the PIs propose to develop, fabricate, test, and deploy swarms of mini-floats that are spatially geo-referenced and temporally synchronized. The plan is facilitated by the design of a new buoyancy control mechanism that will permit the current Autonomous Underwater Explorer (AUE) vehicles and a newer, smaller, 1 liter sized MINI-AUE vehicle to autonomously profile and then surface to establish satellite communication. To test the development, the PIs will use the vehicles in a scientific program to quantify trajectories of meroplanktonic larvae in the coastal ocean, and investigate advection and patch formation of neutrally buoyant and swimming plankton in nonlinear internal waves. At the conclusion of the project, the PIs hope to demonstrate the utility of these mini floats in ocean research and also have a small fleet of such vehicles for future work. Broader Impacts:This proposal has an extensive broader impact component. Beyond developing a tool that will transform coastal studies of physical dynamics and plankton (dispersal, accumulation etc') it involves an important outreach component involving middle and high school students. The students will get to build a float and track it. This is the type of activities that are likely to excite youth to pursue science in general and oceanography/engineering in particular. A post-doctoral scholar will also be funded on this project who will gain valuable engineering/oceanographic experience within a cutting edge lab.

“该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。” PIS请求资金以开发下一代的微型浮动，以实现电流和环境变量的现场测量（荧光，温度，温度，PAR）。这些微型浮游物的主要目标是在高时空分辨率（分钟）下以同时的空间分辨率为10米。为了实现这一目标，PI提出了开发，制造，测试和部署在空间地理参考并在时间上同步的迷你浮游的群。该计划是通过设计新的浮力控制机制来促进的，该机制将允许当前的自主水下资源管理器（AUE）车辆和一辆更新的，更小的1升大小的迷你AUE车辆自动构造，然后浮出水面以建立卫星通信。为了测试开发，PI将在科学计划中使用这些车辆来量化沿海海洋中Meroplanktonic幼虫的轨迹，并研究非线性内波中中性浮力和游泳浮游生物的对流和斑块形成。在该项目结束时，PIS希望证明这些迷你浮子在海洋研究中的实用性，并拥有一小架此类车辆以供将来的工作。 更广泛的影响：该提案具有更广泛的影响组成部分。除了开发一种可以改变物理动态和浮游生物（分散，积累等）沿海研究的工具，它涉及涉及中学生和高中生的重要外展部分。学生将建造浮动并跟踪它。这是一种可能激发年轻人尤其是一般科学和海洋学/工程学的活动的类型。博士后学者还将在该项目上资助，该项目将在尖端实验室中获得宝贵的工程/海洋学经验。
