Sažetak
The study of the physico-chemical properties and the determination of different classes of organic substances in the sea are of substantial interest and importance for understanding biogeochemical processes in the sea. The preferable method should be sensitive enough for direct measurement without pretreatment procedures in order to avoid changes in the composition of organic substances initially present in the sample. Surfactant activity data are presented here as measured by electrochemical methods during 1979, 1980 and 1981 in samples from open waters of the Western Mediterranean, and in a few characteristic coastal areas of the Adriatic Sea with different biological activity and different influence of man's activities. Data on sea surface microlayer samples collected during 1977, 1978 and 1981 at different locations and seasons in the Rijeka Bay, which is an integral part of the Adriatic Sea, are presented and discussed in more detail. It was found that the type and concentration of natural surface active material vary within different Mediterranean regions and along the depth profile of the water column.
