Then, about sixteen minutes into recording, I notice a faint gurgling, like the last remnants of water disappearing down a plug hole. The sound getting slowly louder and more distinct, until it reaches a point where I hear it close enough for me to be worried about the safety of the hydrophones and my recorder, to which they are securely attached.

It’s interesting that I feel more at peace listening to church services from the outside than the inside these days (well at least on warmer, sunnier days!).
