On accounting the vertical distribution of sound velocity when measuring the depth of a water body

Investigates methods for taking into account the influence of the vertical distribution of sound velocity (VDSV) in determining of reservoir depth. Various algorithms for determining the depth of the reflecting object location are given, taking into account the changing of the sound velocity value, and an optimal algorithm in terms of the smallest error is proposed. Using the example of calculating the distance to the reflecting object in the conditions of winter hydrology of shallow northern seas and summer hydrology of deep seas of the North Pacific Ocean, a comparative analysis of the inaccuracy in measuring the depth of the reflecting object is performed.
