Show affiliationsAn existing array of underwater, large-bandwidth acoustic sensors has been used to study the detection of ultra-high-energy (UHE) neutrinos in cosmic rays. Acoustic data from a subset of seven hydrophones located at a depth of ~1600 m have been acquired for a total live time of 195 days. For the first time, a large sample of acoustic background events has been studied for the purpose of extracting signals from super-EeV showers. As a test of the technique, an upper limit for the flux of UHE neutrinos is presented, along with considerations relevant to the design of an acoustic array optimized for neutrino detection.
