p. 83 - 112 CONTRIBUTIONS TO THE KNOWLEDGE OF THE FOULING ON THE ROMANIAN MARITIME SHIPS M.T. Gomoiu and V. Tiganus Romanian Marine Research Institute Constantza Abstract The authors conducted a qualitative and quantitative analysis of the fouling on the Romanian ships harboured in Constantza - Black Sea, on the basis of 152 samples collected from the keel of 16 ships having operated in different geographical areas. The results obtained are correlated with the utilization rate of the ships and with the main geographical areas travelled by them (the Black Sea - Romanian shore, the Black Sea - the Mediterranean and the Black Sea - the Mediterranean - other seas).
