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的要求资金购买两个自主系泊剖面仪，和一套传感器的每个平台，部署在湖上级，世界？世界上最大的淡水湖。所要求的仪器将提供与地球化学过程有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，由于该地区冰盖的变化，现有数据非常稀少，这对于冰基观测来说不够稳定，但足够强大，可以排除该地区任何现有研究船的工作。两个自主系泊剖面仪的使用将允许PI详细说明近岸与离岸regimes.Broader影响的地球化学过程的重要性：明尼苏达大学德卢斯有一个坚定的承诺，本科教育，是其主要重点。大型湖泊观测站（LLO）将其与出色的研究记录相结合。这项研究将扩大我们对大型湖泊内部复杂运作的了解。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。这是一个新的和潜在的有价值的应用相对较新的和未经证实的类剖析仪，具有很高的成功概率，并有助于测试和演示这一新兴类剖析仪具有很高的价值，研究界。
