the deep sound channel of acoustic waves propagation (or: spreading)
Explanation:
Речь здесь идет не о передаче звука (sound transmission), а о распространении звуковых волн в толще океанских вод. Подводный звуковой канал - это не кабель, а явление, заключающееся в "концентрировании" звуковых волн в пределах некоего горизонта, вдоль которого они распространяются на многие тысячи километров без видимых энергентических потерь.

In English: sound (or acoustic) waves propagation within a deep sound channel.

Описание явления по-русски:
В согласии с законом Снеллиуса звуковые волны заворачивают сверху и снизу в сторону горизонта z0 соответствующего
минимуму скорости звука. Все лучи вьются вокруг этого горизонта, что приводит к концентрации энергии на глубинах, где скорость звука минимальна. Такое распространение является волноводным, а образовавшийся в глубинах океана волновод называют подводным звуковым каналом (ПЗК).

Описание по-английски:
Between the negative speed gradient of the permanent thermocline and the positive gradient of the deep isothermal layer, there is a speed minimum toward which sound traveling at great depths tends to be bent or focused by refraction. This is the deep sound channel....
The region of minimum sound velocity, at a depth exceeding a kilometer, is the deep sound channel. It acts as an acoustic waveguide; sound propagating either upward or downward encounters sound-velocity gradients and bends back into this channel. Within the deep sound
channel, sound undergoes only a cylindrical spreading loss, in which intensity drops off only as the first power of the distance.

underwater (or even in-water) channel for propagation of acoustic waves


Explanation:
They mean another mean for propagation of sound waves. This is a phenomenon, not a phisical device:)

Note that some years ago in our city this problem was theoretically resolved and the most interesting is that to solve it one should apply ... so-called fractional derivatives:) and fractals!

Your also may write using in-water see channels for propagation of acoustic waves.
Yours,
Tagir.
