,Importance of Sedimentary Processes in Environmental Changes: Lower River Danube — Danube Delta — Wube River determines the sedimentation on the northwestern Black Sea shelf area. The Danube influence extends down to the deep sea floor. In turn the Black Sea strictly controls the sedimentation of the Danube material through the sea level variations. Danube Delta is acting as a regulator of the se身心疲惫 发表于 2025-3-26 15:04:27

Eutrophication: A Plausible Cause for Changes in Hydrochemical Structure of the Black Sea Anoxic La 1960 to 1995. The results reveal notable changes (increase in the inventories of nutrient and sulfide) in the chemical structure of the anoxic zone, which has been considered for a long time as a conservative layer of the Black Sea. It is inferred that intensive eutrophication is the main reason ofARENA 发表于 2025-3-26 21:15:26
The Suboxic Zone of the Black Sea,t the oxic-anoxic interface. The suboxic zone was defined as the region where the concentrations of oxygen and sulfide were both extremely low and had no perceptible vertical or horizontal gradients. The suboxic zone is a site of intensive redox cycling of species of sulfur, nitrogen, manganese andairborne 发表于 2025-3-27 03:01:33
An Approach to Modelling Anoxic Conditions in the Black Sea,quires parameterization of the cycles of several elements simultaneously, in contrast to models dealing only with nutrient cycles under oxic conditions, where it is possible to use the Redfield ratios. An O-N-S-Mn model is considered to describe the biogeochemical sources. Rates of biochemical procefigurine 发表于 2025-3-27 09:09:46
