p. 273 - 281 BOUEES OCEANOGRAPHIQUES ELEMENTS DE CALCUL DU SUPPORT MARIN D. Dinu Institut Roumain de Recherches Marines Constanta Abstract Following an introduction in which is described the importance of buoys and buoys systems for the scien- tific research of marine environment, a classifica- tion is proposed of these based on several main criteria. A draft of dealing with all calculations in designing the marine support of the oceanographic buoys represents the main part of the paper. Forces actionating on the buoys, the dimensions of the anchoring systems, oscillatory movings on the waves, materials used for construction are presented.
