The invention relates to the technical field of hydrological testing, and provides a marine hydrological winch sounding system and method. The system comprises an angle sensor which is used for obtaining the deviation direction angle of a steel cable of a hydrological winch when an underwater measurer is in an underwater state; a rope length encoder which is used for calculating the length of a water entry rope according to the time nodes of the water entry state and the bottom detection state of the underwater detector; and a water depth measuring instrument which is respectively connected with the angle sensor and the rope length encoder and is used for obtaining the deviation direction angle obtained by the angle sensor and the water entry rope length parameter obtained through calculation according to the time nodes of the water entry state and the bottom detection state of the underwater detector, and calculating the water depth parameter according to the obtained deviation direction angle and the water entry rope length parameter, so that the problem that the hydrological winch generates the sounding errors due to the influence of a deflection angle is solved, and the sounding accuracy and effectiveness are improved.
