In the Romanian shelf region, the silicate and phosphate stocks have decreased slowly since 1974, with an increasing trend in the silicate again in more recent years.

A subsurface Chernobyl Cs maximum near the Bosporus found in both 1987 and 1988 suggests that at least part of this vertical mixing process occurs as entrainment driven mixing near the Bosphorus.
