Listening to the Deep: 46 Hours of Acoustic Data from an Offshore Platform

A 24.41 Hz fundamental tone, measured at 122.29 dB re 1μPa²/Hz, dominates the underwater acoustic signature of a large truss-type offshore aquaculture platform, roughly 16 dB above idle. This 46-hour campaign under calm seas confirms that structural vibrations from the propulsion system travel through the rigid pile foundation, not through the water column. Above 2 kHz, platform noise vanishes into the background. Day-night shifts in the sound-speed profile and semi-diurnal tidal modulation further shape this soundscape.
