Generalization of the results of years of research on the geochemistry of trace elements in the interstitial waters and sediments of the Black sea. The works were carried out in different areas, but in more detail described the material on the deep-water basin and facies profiles Yalta, Sochi landfills and profile directed from the Kerch Strait to SE. The behavior of biogenic elements (N, P, Si), B, J, Br and 18 metal elements according to ISP and ISP-MS is studied. Average concentrations of elements for 3 stratigraphic horizons are calculated. Factor analysis was used to process the results.

Deep Water Basin

One of the important unsolved problems related to the evolution of living conditions on Earth is the mechanism of the rapid transformation of the Black Sea from a shallow lake-type sea into a deep-water basin, the earth's crust in the central part of which does not have a granite layer. There is no explanation as to how “granite-free depressions” were formed at the bottom of the sea, which are currently covered by sediment. Investigations of these processes were started in the middle of the last century by scientists-geologists of the Institute of Oceanology of the Russian Academy of Sciences and its South. In this article, the authors propose a mechanism for the destruction of the earth's crust and the formation of depressions in the inner seas during the Messinian crisis.

The chemical composition of interstitial waters from several of inland seas and NPWS, exposed to anthropogenic pollution. The regularities of distribution of pollution in the Dnieper-Bug estuary and Gelendzhik Bay of the Black sea in the Eastern Harbor of Alexandria Mediterranean Sea. Most of the contamination confines to the upper layers of sediments and near mouth zones. A significant role is played by secondary contamination related to the dissolution and accumulation of metals and nutrients in the interstitial water and their migration in the water column. When factor analysis for the aggregate impact of potentially mobile forms of metals in the Diepr-Bug estuary factor of anthropogenic pollution came in first place. Studies pollution in the Pjasino Lake near town Norilsk.

The concept of a new approach to environmental assessment is offered in the system of integrated management of the resource and environmental safety of the coastal area of the Black Sea. The studies of the season and daily changeability in the bioluminescence field in the Sevastopol coastal waters has been conducted. For the first time considerable differences in the bioluminescence field seasonal changes in the surface and deep water layers and the reasons conditioning this phenomenon have been shown, using a method of multidimensional statistical analysis. The bioluminescence field vertical profile change in the Black sea coastal waters in the autumn period at night has been studied. It has been shown that according to the character of bioluminescence parameters dynamics a water column can be divided into layers: upper (0 – 35 m) and deep water (36 – 60 m). It has been revealed that life rhythms of the plankton community are the main reason for the bioluminescence field intensity variability. It has been revealed that 14-hour periodicity of the bioluminescence field is related to the changes in light and its variations with 2,5…4,5 hours are conditioned by planktonts endogenous daily rhythms. And here biotic factors effect mostly periodicity of the bioluminescence field intensity increase and fall down at the dark time of the day. Abiotic factors are of less importance in circadian rhythmic of the bioluminescence field in the neritic zone.
