Abstract:

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 CO32- 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.

Key words: hydrothermal vents, abnormal water, chemical sensors, Southwest Indian Ridge
