The PI's request funding to acquire two Autonomous Moored Profilers, and a suite of sensors for each platform, for deployment in Lake Superior, the world?s largest freshwater lake by area. The requested instrumentation will provide physical, biological, and chemical data on timescales relevant to biogeochemical processes, and will expand this detailed view into the winter season, for which existing data is extremely sparse due to the variable ice cover in this region, which is not stable enough for ice-based observations but is sufficiently robust to preclude work on any of the available research vessels in the region. The use of two autonomous moored profilers will allow the PI's to detail the importance of biogeochemical processes in nearshore vs offshore regimes.Broader Impacts: The University of Minnesota-Duluth has a strong commitment to undergraduate education, being its principal focus. The Large Lakes Observatory (LLO) combines that with an excellent track record in research. The study will expand our knowledge of the intricacies of the inner workings of large lakes. The close integration of project research with education will most certainly enhance experience for students both undergraduates and graduates and inform the public. This is a new and potentially valuable application for a relatively new and unproven class of profiler that has a high probability of success and contributing to the testing and demonstration of this emerging class of profilers has high value to the research community.

PI 请求资金购买两台自主系泊剖面仪，并为每个平台配备一套传感器，以便部署在世界上面积最大的淡水湖苏必利尔湖。所需的仪器将提供与生物地球化学过程相关的时间尺度上的物理、生物和化学数据，并将这一详细视图扩展到冬季，由于该地区冰盖变化无常，现有数据极其稀疏，而冬季的数据却非常稀疏。足够稳定，可以进行冰基观测，但也足够坚固，无法在该地区任何可用的研究船上进行工作。使用两个自主系泊剖面仪将使 PI 能够详细说明近岸与近海区域中生物地球化学过程的重要性。更广泛的影响：明尼苏达大学德卢斯分校坚定地致力于本科教育，这是其主要重点。大湖天文台 (LLO) 将这一点与卓越的研究记录结合起来。这项研究将扩大我们对大型湖泊内部运作的复杂性的了解。项目研究与教育的紧密结合肯定会增强本科生和研究生的经验，并告知公众。对于相对较新且未经证实的分析器类别来说，这是一个新的且具有潜在价值的应用程序，它成功的可能性很高，并且有助于测试和演示这一新兴类别的分析器，对研究界具有很高的价值。
