The possibility of converted hydroacoustic arrays to create a module of deep water ν-Telescope is discussed. The array MC-10M is good tool to start the first real ocean experiments to investigate the problem of detecting neutrinos with energy 1018 eV. Technical parameters and systems which are necessary to create the module are presented. The Mediterranean Sea is an appropriate area for the first experiments due to existing of a deep underwater sound channel and stable high temperature. Some estimation of possible detecting volumes is presented. This project is continuation of works of authors in this direction, started in 1997.

The geographic distribution of Verruca stroemia and V. spengleri are reviewed. Verruca stroemia ranges from the White, Barents, Norwegian, and North Seas south to Portugal to the Algarve and to Gorringe Bank. All of the records of this species from the Mediterranean Sea are considered to be V. spengleri. Verruca spengleri occurs in the Azores and Madeira archipelagos, in southern Spain (Cádiz), throughout the Mediterranean Sea from Gibraltar to Lebanon, and in the Black Sea. But a distinct deep-water Verruca species seems to occur in the deep Mediterranean.

The first activities related to acoustic detection of particles by DISAO research group in the Univesitat Politècnica de València are described. We are applying some techniques from physic, engineering and oceanographic acoustics to face the high energy neutrino underwater acoustic detection challenge. The work is focused mainly in two topics: design, characterization and calibration of hydrophones, and simulation of the propagation of the signal in the sea. We present also some examples for these two topics: piezoelectric modelling and transducer simulation, calibration of hydrophones using MLS signals, and evaluation of the contribution of the sea surface noise to the deep water noise in the Mediterranean Sea by means of simulations of propagation of sound.
