Remote Real-Time Profiling of Surface Seawater CO2 at the LEO-15 Site

9812513名德格兰普大学的科学家。蒙大拿州大学、罗格斯大学和伍兹霍尔海洋研究所将合作，利用罗格斯大学长期地球天文台(LEO-15)的水下技术开发海洋二氧化碳剖面能力，其次，表征这一沿海位置的二氧化碳变异性。工作将包括加强现有的概况分析系统，使其能够从自主生物地球化学传感器获取数据，包括一个潜水式自主系泊二氧化碳传感器(SAMI-CO2)、氧气和光传感器以及一个叶绿素荧光计。该剖面系统将获得时间和深度分辨的二氧化碳、计算的总二氧化碳(TCO2)、溶解的O2、叶绿素荧光和光强度。二氧化碳的高分辨率垂直测量与其他生物地球化学参数相结合，将为生物地球化学模型和估计水柱生物地球化学清单提供必要的数据。实时数据采集和远程控制剖面仪将用于测试有关二氧化碳循环的具体问题。这项工作将确定二氧化碳剖面图是否显著提高了我们研究和理解海洋二氧化碳循环的能力。如果被证明是成功的，这项研究可能会为全球规模的原位生物地球化学剖面仪网络奠定基础，以表征海洋生物地球化学循环。

9812513 DeGrandpre Scientists at the Univ. of Montana, Rutgers University, and Woods Hole Oceanographic Institution will collaborate to develop an ocean CO2 profiling capability using underwater technology at Rutgers University's Long-term Earth Observatory (LEO-15) and secondly, to characterize CO2 variability at this coastal location. Work will consist of augmenting an existing profiling system so that it will acquire data from autonomous biogeochemical sensors, including a Submersible Autonomous Moored Instrument for CO2 (SAMI-CO2), O2 and light sensors, and a chlorophyll fluorometer. The profiling system will obtain time and depth-resolved PCO2 , calculated total CO2 (TCO2 ), dissolved 02, chlorophyll fluorescence and light intensity. The high resolution vertical measurements of CO2 , in combination with the other biogeochemical parameters, will provide necessary data for biogeochemical models and for estimating water column biogeochemical inventories. Real-time data acquisition and remote control of the profiler will be incorporated for testing specific questions regarding CO2 cycling. The work will determine if CO2 profiling significantly advances our ability to study and understand the marine CO2 cycle. If proven successful, the research may set the groundwork for a global scale network of in situ biogeochemical profilers to characterize ocean biogeochemical cycles.
