The Tutorial Course for Young Acousticians from European Countries will be organised under the sheme of 6th Conference on Underwater Acoustics ECUA'2002, which will be held from 24-27 June 2002 in Gdansk, Poland -candidate country tothe European Union. The topic of the course is Underwater Acoustics and Remote Sensing Technologies for Exploration and Sustainable Exploitation of Marine Ecosystems. The course will consists of seven lectures grouped in two sessions, one plenary session (theoretically oriented) and two parallel sessions (more practically oriented). The topics of plenary talk will cover in general problems of propagation and scattering of acoustics waves in the sea, while the parallel sessions will deal with computational acoustics, modelling and imaging. The lectures will be delivered by outstanding European and American acousticians.
