The Nutrient Stock of the Romanian Shelf of the Black Sea During the Last Three Decades,to be one of the severely polluted rivers over the world. 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. The N:P ratio of the shelf water, usually between 20 and 130, is comparable虚弱 发表于 2025-3-30 18:31:36

Long-Term Variability of Phytoplankton Communities in Open Black Sea in Relation to Environmental Chytoplankton groups was evident in the 1992–1995 period, during which an increase of diatoms and a decrease of dinoflagellates was also observed. The analysis of changes in zooplankton communities occurring after the . intrusion have shown that grazing control was not the main factor determining tot倒转 发表于 2025-3-31 04:35:16

Time-Series Profiles of 134CS, 137CS and 90SR in the Black Sea,nter cooling and mixing, and the overall water and salt balances. 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.
