Abstract : The CTBTO (Comprehensive Test Ban Treaty Organization) Hydroacoustic sites have been operational for (depending on location) up to 10+ years. The sites are under the National control of the countries Australia, Canada, Chile, France, Mexico, Portugal, UK of Great Britain & Northern Ireland and the United States. The data is a continuous stream of ambient noise, from each sensor the interest is in long term ambient noise recordings; study of specific source functions and their temporal behavior. The frequency range of the system is limited to approximately 1 to 100 Hertz, with the consequent restriction of potential noise sources at Wake Island, Ascension Island and Diego Garcia.
