Abstract
The authors present in the paper the feautures of marine water 
salinity regime in the south part of the Black Sea Roumain 
littoral, in the 1970 year with unusual high flow of the Danube
river. On the basis of the observations carried out daily in the
shallow water near Constantza, and mounthly, off shore on the East
Constantza profile, 30 nautical miles for from the shore, it is 
show that the strouyest influence of the Danube fresh water have 
been registred in the July - September period in the shallow zones
and in the May-September period the off sea zones.
The minimum values of the salinity registered during in the 1970 in
the 0-30m water column, were much smaller than the smallest values
known until today, fact wich attest this influence exerted by the big
flow of the Danube river - 1970.
