Abstract
Based on daily-performed observations at Constanta during 1959-1979,
the paper follows the general tendency of salinity, oxygen and 
nutrient evolution in the shallow waters along the Romanian coast
of the Black Sea. At the same time, important quantitative changes
are identified in the annual cycle and multiannual dynamics, as
generated by the variability of the hydrological and hydrobiological
agents characteristic of the studied area.
