Abstract: Ocean noise has typically been treated as unwanted interference in the context of detecting signals. However, more recently, noise has itself also become a signal of interest in which, for example, ocean or geophysical properties are embedded in the noise field. There is now significant ongoing research in trying to extract environmental information from noise. Much of the latter has utilized man-made noise, surface generated noise, biological noise or seismic noise. In this talk, a brief review of the transition of some noise research to a new focus on useful aspects of noise will be given.
