,Importance of Sedimentary Processes in Environmental Changes: Lower River Danube — Danube Delta — Wdiment transfer between the Danube River and the Black Sea. The three factors -river, delta and marine basin- make up a well-established geosystem. Our present interest will concentrate on the sedimentary cycle including the Romanian Carpathians source area, the Lower Danube transport agent and the western Black Sea accumulation basin (Fig. 1).

Eutrophication: A Plausible Cause for Changes in Hydrochemical Structure of the Black Sea Anoxic La the change. The results of the analysis of long-term variations in chemical structure demonstrate not only intensive degradation of the ecosystem of the Black Sea in 70’s and 80’s, but also relative improvement of the situation in 90’s.

Towards Development of an Operational Marine Services System in the Black Sea,ons. BLACKMARS is to be based on cooperative efforts of all riparian countries. The main activity within BLACKMARS will be the organisation of operational generation and distribution of real — time marine meteorological and oceanographic products based on observations and up-to-date numerical models in accordance with regional user requirements.

Characteristic Chemical Features and Biogeochemical Cycles in the Black Sea,have also been evaluated for describing the possible routes and mechanisms of transport of coastally trapped pollutants into the offshore, deep-basin waters through meandering rim current system, and the redox mechanisms controlling the sub-oxic zone located between oxic and anoxic layers.

The most favourite model is the back-arc opening. In these models various age estimates, ranging from pre-Cambrian to Quaternary have been proposed, although mid-Cretaceous has gained a wide support.
