If there is a bird chirping in the woods, where do you hear the chirp? Does that change when the wind is blowing, when you are near trees or cliffs?

A lot of things affect the way sound moves through water. Changes in depth, temperature, and salinity will cause sound to move faster or slower and curve the direction in which it travels. Layers of warmer and colder water can trap the sound, like trying to transmit it through the roof of your house. As sound curves upwards it converges and can literally bounce off the surface only to be detectable again miles away. These don't prevent you from narrowing down the location of the sound source but they do make it more challenging.
