Abstract 
Based on daily-performed observations in the Danube and inshore
marine waters during 1980-1981, the paper follows the seasonal
and yearly variations of the main chemical agents. The influence
of Danube waters on the distribution of salinity,oxygen, organic
matter (as oxydability) and nutrients in marine water along the
Romanian coast of the Black Sea is discussed.
