Summary: | An attractive technique to explore for super-high-energy cosmic neutrino fluxes, via deep underwater acoustic detection, is discussed. Acoustic signals emitted by the neutrino induced cascades at large distances (10-50 km) from cascades are considered. It is argued that an existing hydroacoustic array of 2400 hydrophones, which is available in the Great Ocean near Kamchatka Peninsula, could be used as a base for an exploratory acoustic neutrino telescope SADCO (Sea Acoustic Detector of Cosmic Objects). The detection volume for registration of cascades with energies in the range of 10 20−21 eV is estimated to be hundreds of cubic kilometers. Some models of extremely high energy elementary particle production in the Universe (for example the topological defect model) may be examined by such a detector. Tests of this technique are hoped for within a year. |
