aims to detect comic ray neutrinos of GZK energies and beyond<br>
(>10^18eV) acoustically by utilizing the ocean water as the target and an existing US Navy underwater microphone array as sensors. A DAQ system was developed and deployed in 2005. The experiment ran during 2006 and 2007, collecting over 1 TB of data with over 100 days of cumulative livetime. A study of the ocean ambient noise was performed using SAUND data, characterising the background for neutrino signals. Data analysis to isolate signals is performed in parallel to Monte Carlo studies of the detector to optimize cut efficiencies and set a neutrino flux limit in the ultra-high energy region.
