Moored Arrays to Measure Total System Metabolism in Estuaries

该海洋仪器开发项目是设计和现场测试系泊仪器阵列的第一步，以便能够测量沿海水域和河口的总系统代谢(TSM)。新的能力将允许在以前不切实际的复杂水文条件下应用TSM测量技术。测试系泊设备将配备紧密间隔的脉冲氧传感器和其他探头。数据将被收集和存储长达30天。目标是测试传感器的长期稳定性和准确性，以及能否以足够的分辨率获得频繁的垂直氧分压剖面，以在确定的研究区域内建立氧的质量平衡。这项工作将提供确凿的证据，证明脉冲氧传感器在系泊和其他长期远程应用中的有效性。

This oceanographic instrumentation development project is the first step towards the design and field testing of a moored instrument array to allow measurement of Total System Metabolism (TSM) in coastal waters and estuaries. The new capability will allow the application of TSM measurement techniques in complex hydrographic conditions where they have previously been impractical. The test mooring will have closely spaced pulsed oxygen sensors and other probes. Data will be collected and stored for periods up to thirty days. The goal is to test the sensors' long-term stability and accuracy and whether frequent vertical profiles of oxygen partial pressure can be made with sufficient resolution to construct mass balances of oxygen within a defined study area. The work will provide conclusive evidence as to the usefulness of pulsed oxygen sensors on moorings and other long-term remote applications.
