The present paper describes the GasPro probe, a small, low-cost unit for in situ, continuous pCO2 monitoring. Laboratory tests defining its performance characteristics are reported, as are the results from a 60 h water-column deployment of 20 such units near a natural CO2 seep site off the coast of Panarea Island (Italy). The spatial-temporal evolution of dissolved CO2 movement is presented and possible origins and controlling mechanisms discussed. Results highlight the potential for this technology to be used for better understanding various dynamic physical and biochemical processes in marine environments, and for marine environmental monitoring of off-shore industrial sites. These experiments have allowed us to assess the advantages and disadvantages of the present GasPro prototype and to define areas for ongoing improvement.
本文介绍了 GasPro 探头，这是一种用于原位、连续 pCO2 监测的小型、低成本设备。本文报告了定义其性能特征的实验室测试结果，以及在意大利帕拉雷亚岛（Panarea Island）海岸附近的一个天然 CO2 渗漏点附近部署 20 个这种探头 60 小时的水柱结果。本文呈现了溶解 CO2 运动的时空演化，并讨论了可能的起源和控制机制。结果强调了这项技术在更好地理解海洋环境中的各种动态物理和生化过程以及近海工业场地的海洋环境监测方面的潜力。这些实验使我们能够评估当前 GasPro 原型的优缺点，并确定持续改进的领域。
