Abstract

Abstract

On the basis of chemical anomalies between hydrothermal plumes and surrounding seawater a means of detecting hydrothermal activity is proposed. Therefore, a multiparameter chemical sensor integrating three types of electrochemical electrodes, including Eh, Ag/Ag₂S and pH electrodes, is designed to be applied in deep-sea measurements during DY115-20 cruise by Dayang No.1 research vessel. It is proved by the measuring results that the multiparameter chemical sensor can help to detect the chemical anomalies of the plumes. The electrodes exhibit good sensitivity, stability and long lifetime in the multiple applications during six months. Among the 60 measurements in both East Pacific Ridge (EPR) and Southwest Indian Ridge (SWIR), the integrated sensor records 55 groups of valid data, in which 29 records indicate potential active hydrothermal vents, which proves an effective tool in hydrothermal activity detection.
