En eau profonde (à plus de 2000 m), le chenal sonore profond permet aux sons réfractés de parcourir de grandes distances sans perte due à la réflexion sur le fond en raison de la vitesse de la réfraction ascendante du son sous le chenal sonore profond. La profondeur de ce chenal se situe autour de 1000 m à des latitudes moyennes, et à la surface à des latitudes élevées. 1, record 1, French, - chenal%20sonore%20profond
