Description
Summary:The first pilot experiment on transarctic underice low-frequency (LF) sound propagation in Arctic Ocean-Transarctic Acoustic Propagation (TAP) experiment was successfully carried out in April, 1994. This experiment was performed by American, Canadian and Russian scientists. The acoustic data provided by tone and complex signals propagation along paths of lengths approx. 900 km and approx. 2600 km were collected within 5 days. The TAP experiment has confirmed the principle possibility of observing rather low temperature water-mass trends and averaged over Arctic ice cover characteristics provided by long-term observation of variable phase, propagation time and amplitude of acoustic signals. Acoustic monitoring of climatic variations and study of temperature noises caused by space-time variability of dynamic processes in the Arctic Ocean will require the arrangement of an acoustic network capable of at least ten year functioning. The new program - Arctic Climate Observations using Underwater Sound (ACOUS) being developed for these purposes implies at the first stage arranging continuous collection of acoustic data on paths similar to TAP experiment during 1996-1997.
