Low-Frequency Sound Sources for Acoustic Thermometry and Navigation in the Arctic
Abstract
The acquisition of a new low-frequency sound source (~ 20 Hz) would augment two existing low-frequency sound-sources and would allow an Arctic basin-wide thermometry and navigation network. The Acoustical Oceanography group at the Scripps Institution of Oceanography owns two ONR funded low-frequency sound sources that are currently deployed in an Arctic transbasin acoustics experiment, CAATEX. A third source would allow for the unambiguous localization of autonomous vehicles throughout much of the Arctic Ocean. The use of lowfrequency with long integration times also allows full depth coverage of the signals as well as the acquisition of bearing angle information from moving autonomous vehicles. We anticipate that data obtained in future ocean acoustic experiments from upgraded sound-sources will contribute to the education and research of graduate students and post-graduate researchers, just as the data obtained using the existing sound-sources has.
