摘　　要：海底热液喷口周围的水体具有显著的浊度和化学组分异常,是寻找热液喷口的重要标志。文章提出了一种海底热液喷口的探测技术方法,设计了低功耗化学传感器。该化学传感器可搭载在相关平台,实时探测水体的Eh、H_2S、pH及CO_3^(2-)等电位值,结合浊度异常,可以推断热液喷口的位置。在西南印度洋中脊海试结果表明,该化学传感器可有效探测由热液活动产生的水体异常,是一种探测海底热液喷口的有效技术。The water around submarine hydrothermal vents has significant turbidity and chemical composition anomalies,providing an important indicator for finding hydrothermal vents.In this paper,a detection method of submarine hydrothermal vents was proposed,and a low-power chemical sensor hydrothermal detection system was designed.The chemical sensor can detect real-time potential values of pH,H2S,Eh,and CO3 2?when mounted on the relevant detection platform.Combined with abnormal turbidity,we can infer the location of hydrothermal vents.The results of the testing in the Southwest Indian Ridge showed that the chemical sensor can effectively detect chemical abnormalities caused by hydrothermal activity,which is an effective technique for detecting hydrothermal vents.
