APL-UW Next Generation Oceanic Noiseology
Abstract
Decades of ocean acousticians have become familiar with, and usually annoyed by, oceanic ambient noise in their efforts to tease out from this noise their signals of interest. This oceanic ambient noise, however, contains components from a multitude of sound mechanisms, and therefore carries information about those mechanisms. In the evolutionary process of trying to understand the oceanic environment, oceanic ambient noise has become the signal of interest. This proposal seeks to expand the science of ambient noise itself, using novel processing and analysis methods on data acquired from existing systems to gain information regarding the mechanisms driving long term trends in noise, which in turn involve the spatial distribution of sources in the North Pacific Ocean, the heat content of the deep ocean, and changes in the earth-ocean climate. In addition, maintenance will continue on the Kauai source.
