A major project, called the NATO TU-WAVES Project, which aims to find out the wave climate affecting the whole Black Sea as well as the Turkish coasts on other seas, is being carried out since the beginning of 1994 within the framework of the NATO SfS Program-Phase III. The main objectives of this project are to obtain detailed knowledge on and to establish a reliable data bank of wind waves affecting the whole Black Sea and the other Turkish coasts, to implement a third generation wave model for the seas surrounding Turkey, and to construct a wave atlas for the Black Sea and the other Turkish coasts. The "Black-Sea Wave Atlas", which is expected to be ready by the end of 1998, will provide accurate and reliable information on sea state parameters needed for most coastal and marine activities. In addition to METU-KLARE, the lead organization, three Turkish organizations and eight other institutes from four Black Sea riparian countries (Bulgaria, Rumania, Russia and Ukraine) are collaborating within the framework of the NATO TU-WAVES Project. This paper briefly describes this project and the progress of its activities.
