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.

这个海洋仪器开发项目是 设计和现场测试的第一步， 系泊的仪器阵列，以便测量 系统代谢（TSM）在沿海沃茨和河口。 新功能将允许应用TSM 复杂水文条件下的测量技术 在以前是不切实际的。 测试 系泊处将有密集的脉冲氧传感器， 其他探头。 数据将被收集和存储， 最长30天。 目标是测试 传感器的长期稳定性和准确性， 氧分压的频繁垂直分布可 以足够的分辨率来构造质量 在确定的研究区域内的氧气平衡。 工作 将提供决定性的证据， 脉冲氧传感器在系泊和其他长期 远程应用。
