Abstract
One characteristic of deep ocean noise is the decrease in ambient levels below the conjugate depth (Urick, 1975). Measurements made by Gaul et al. (JOE, 2007) and Morris (JASA, 1978) in the North Pacific indicate that the slope of the noise below the conjugate depth varies with location. Gaul et al.'s measurements show a much steeper slope than those of Morris, and this difference can be attributed to bathymetric effects (Shooter, JOE, 1990). The experiments described by Gaul et al. and Morris took place in September 1975 and September 1973, respectively. Noise levels measured during SPICEX in September 2004 are comparable to those recorded by Morris 31 years earlier. While the earlier experiments took place over 2–11 day periods, the SPICEX arrays were deployed for a year. Since the conjugate depth varies seasonally, it is expected that the noise profile also varies seasonally. This talk investigates the seasonal variations of noise in the SPICEX data set, focusing on the 10–100 Hz band. The analysis includes a discussion of the effects of local wind.
