The Depth Profile of Ambient Noise in the Deep Sea North of St. Croix, Virgin Islands
Abstract
The deep sea appears to be quieter at mid-depth than at greater or lesser depths. This was found in a series of measurements of the ambient noise background at a location north of St. Croix, V.I., using hydrophones suspended from a cable at intervals of 2000 feet down to 8100 feet. The noise profiles show a sharp decrease of noise from the surface down to 6100 ft and a reversal of the profile below. The measurement site is an active, dynamic one, and shows a large variability in noise level from hour to hour.
