Morphology
The noun is directly compositional: it refers to the act of 'sounding' (measuring depth) by means of an 'echo' (a reflected sound). The meaning follows straightforwardly from combining the two constituents and aligns with similar transparent technical terms in other languages, so learners who know both words can infer the MWE.
Etymology
Echo sounding comes from the simple idea of sending a sound into the water and listening for the echo that comes back. The sounding is the measuring: by timing how long the echo takes, people can find the 'depth' or where things are under the water, so echo sounding means a method to measure depth or locate underwater objects.
