Abstract

The paper discusses the results derived from the analysis of the vertical distribution of nitrates in the Black Sea density field during the winter of 1994. It has been shown that in the absence of winter-time convective mixing of waters, the vertical structure of nitrates is isopycnically defined. Maximum nitrates concentration persists throughout the warm period, normally changing from 5 to 9 μmol in the deep-water part of the area, and has not altered, in comparison with the 1980 data.
