Quarry Dive

This is a clip of an audio recording of a quarry dive. The hydrophone is sitting approximately 5 metres under the water against the side of the rocks. I could not get the microphone any further under as I was seven metres or so above on a mini-cliff which meant throwing the microphone in from height. Boddam Quarry is a fresh-water training site for dive clubs, so at this point there was six divers in total in the water. The nearest they were to me was around twenty metres so the noise of the breathing apparatus was very noisy. This noise was probably emphasised in the enclosed space, the rocks amplifying the acoustics making the sound appear more dramatic and intense.
