MRI: Acquisition of two Autonomous Moored Profilers for Lake Ecosystem Research

国际和平研究所要求提供资金，为每个平台购买两个自主系泊剖面仪和一套传感器，部署在苏必利尔湖--世界上面积最大的淡水湖S。所要求的仪器将提供与生物地球化学过程有关的时间尺度上的物理、生物和化学数据，并将这一详细情况扩展到冬季，由于该区域变化的冰盖，现有数据极为稀少，该区域的冰盖不够稳定，不足以进行冰基观测，但足够坚固，足以排除在该区域任何现有研究船上开展工作的可能性。两个自主的系泊剖面仪的使用将使PI能够详细说明近岸和离岸环境中生物地球化学过程的重要性。广泛的影响：明尼苏达大学德卢斯分校对本科教育有着坚定的承诺，这是它的主要重点。大湖天文台(LLO)将这一点与出色的研究记录结合在一起。这项研究将扩大我们对大型湖泊内部工作机制错综复杂的了解。项目研究与教育的紧密结合肯定会增加本科生和研究生的体验，并向公众提供信息。这是一种新的、潜在有价值的应用，它是一种相对较新且未经证实的剖面仪类别，具有很高的成功几率，对测试和演示这一新兴类别的剖面仪具有很高的研究价值。

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.
