Abstract： Aiming at the special requirements of hydrothermal liquid area environmental parameter acquisition，a drag hydrothermal detection system was designed. MSP430F169 was used as the core micro control unit（MCU）. An external 16 bits A/D converter and two multiplexers were used in the data logger，which highly simplified the electronic circuit design. According to laboratory experiments，the results indicate that the data logger can meet the accuracy and linearity requirements. Through Kueishantao Islet hydrothermal liquid area sea trials，a hydrothermal vent（24.834 19N，121.961 98E） is found 16.7 meters beneath the sea. The reliability of the hydrothermal detection system is further verified.
