Code of Good Practice for the Management of the Underwater Cultural Heritage in the Baltic Sea Region as well as UNESCO convention on underwater cultural heritage consider public access to the good and appropriate information very important. Cooperation between countries is equally important to protect, study and preserve. Raising of public awareness about underwater cultural heritage and its meaning is precondition for participating of society at large. Project can also promote sustainability by mutual activities that can bring to the full scale mapping and opening information about underwater cultural heritage, allowing thus to plan protection- or further archaelogical works or underwater and sea-tourism activities. Many experts can continue later to work with materials dated and mapped by the project. Shipwrecks are a part of international cultural heritage. Very often a single ship brings together several countries via its building location, crew, cargo and wreck location. Because of this inherent internationality, documents regarding the history of any ship are often scattered among the archives of many countries. We will achieve project results with using further methods: 1) Creating and constant filling in the internet based shipwreck registry; 2) Studying and digitizing archive materials in Estonia, Sweden, Denmark and Holland; 3) Underwater archaelogical fieldwork with using sonar and ROV. 5) Public seminar in Sweden and Estonia. 6) Program diving for non-divers in Estonia and Sweden; 7) Guided bus tours to introduce maritime heritage in Sweden; 8) Writing an articles into one book and participation in Swedish conference; 9) Underwater archaelogy fieldwork workshops. 1. Project management and coordination – lead partner responsible, to monitor all other workpackages and exchange all information between partners and provide all necessary reports to JTS. Creates new data base linked to the cultural monument register; provides fieldworks, organizes hobby divers seminar in Estonia; joint field work workshop in Estonia; publishing of the informative folder and the book. 2. National Archives of Estonia is responsible and coordinates activities of WP2 – Archive works and digitizing, working with archive sources, and filling the data base governed by National Heritage Board. 3. Estonian Maritime Museum is responsible for WP 3 fieldworks using sonar and underwater activities; 4. Swedish National Maritime Museums is responsible for WP 4 coordination, provides fieldworks, communication activitis and takes part in fieldworks in Estonia and organizes final conference. All project partners participate in the activities of all other workpackages. Achievements: The main objective of SHIPWHER was to enhance the knowledge about the underwater cultural heritage in Estonia and Sweden, to improve the access to this data, especially regarding ship wrecks, and to provide the general public with opportunities to learn more about the cultural heritage in the waters of the Central Baltic region. The project created an internet-based database connected with the existing databases of the project partners, making it possible for divers and non-divers alike to obtain an overall picture of shipwrecks. By studying and digitalising materials from various countries and carrying out field work, more information has been collected. The project also organised seminars, published a books about the maritime heritage and conducted guided boat tours for the general public.
