The knowledge and “know-how” amassed in the project (WP 1 - WP 3) will be disseminated with a multi-approach in order to reach both the European establishment and institutes responsible for preservation of underwater cultural heritage, as well as the public. A workshop with practical demonstration of methods for preservation in situ will be organised, and scientific publications and contributions at international conferences will be given. Finally a monograph on degradation and preservation of wreck in situ will be published.
