在此，我们提出了一种小型多功能光极系统，带有集成电池和记录仪，用于监测海水中的 O2、pH 和 pCO2。专为海水测量设计的三种传感材料在动态测量范围和长期稳定性方面进行了优化。传感材料的光谱特性经过定制，可与安装在压力外壳中的市售实验室氧气记录仪兼容。具有适当“传感化学”的可互换传感器帽可以方便地连接到光纤末端。这种方法允许使用同一台仪器来分析多种分析物，从而提供了极大的灵活性并最大限度地降低了硬件成本。通过在波罗的海研究巡航期间记录三个参数的深度剖面以及测量地表水横断面的 pH 值，展示了新光极系统的应用。该光极还用于监测丹麦利姆峡湾海草草甸的溶解氧浓度，由 pO2、pH 和 pCO2 组成的传感器包在德国基尔和英国南安普敦的港口部署了 6 天。测量结果表明，该系统可以解析与空间异质性以及生物和潮汐活动引起的时间变化相关的海水化学的典型模式。
Herein, we present a small and versatile optode system with integrated battery and logger for monitoring of O2, pH, and pCO2 in seawater. Three sensing materials designed for seawater measurements are optimized with respect to dynamic measurement range and long‐term stability. The spectral properties of the sensing materials were tailored to be compatible with a commercially available laboratory oxygen logger that was fitted into a pressure housing. Interchangeable sensor caps with appropriate “sensing chemistry” are conveniently attached to the end of the optical fiber. This approach allows using the same instrument for multiple analytes, which offers great flexibility and minimizes hardware costs. Applications of the new optode system were demonstrated by recording depth profiles for the three parameters during a research cruise in the Baltic Sea and by measuring surface water transects of pH. The optode was furthermore used to monitor the concentration of dissolved oxygen in a seagrass meadow in the Limfjord, Denmark, and sensor packages consisting of pO2, pH, and pCO2 were deployed in the harbors of Kiel, Germany, and Southampton, England, for 6 d. The measurements revealed that the system can resolve typical patterns in seawater chemistry related to spatial heterogeneities as well as temporal changes caused by biological and tidal activity.
