To analyze the current state of marine research problems and to formulate proposals for the establishment of a national system of sustainable development of marine research in Ukraine and ways of their implementa-tion. Analysis of current problems in the marine research and respective national and international legal frame-work has been performed. It was shown that the problems of investigations are directly connected with natural and anthropogenic changes and pressures in marine ecosystems. Detailed analysis of national low base present-ed. Some grounded measures and steps to establish the national system for sustainable development of marine studies and technologies in Ukraine have been proposed. Are discussed the actual directions and their im-portance for science and research taking into account the national interests of Ukraine and to ensure compliance with the Association Agreement and other international commitments of Ukraine. The establishment the Black Sea joint international network of reference (basic) marine research stations for using in interests of all the Black Sea countries are proposed. Conclusions: Renovation of national system of the scientific research and technologies cannot be developed without establishing of respective infrastructure, restoration of marine potential and modern system of marine specialists education taking into account experience of European and global science.

The work is devoted to application of the benthic foraminifera for an evaluation of an geoecological situa-tion on a northwest shelf of the Black Sea. The awake role of organisms with carbonaceous function is marked during biological absorption of toxic bonds. The attributes of stressful situations on population and organismic level include a degree of a surviving of species and morphological changes of the foraminifera. These parameters applied for abjection of geographic ranges of a toxic stimulation, development and anomalous morphology of organisms. Purpose. The aim of this work is to analyze the effect of significant cadmium content on benthic foraminifers of the Black Sea shelf (Danube Delta region). Methods. Field studies provided for the selection, documentation and preparation of analytical samples. Micro-paleontological and lithologic-geochemical studies of bottom sediments were carried out in accordance with accepted methods. The method for studying foraminifera includes the following operations: sampling, separation, preservation and preparation for analysis, taxonomic identification, morphological analysis, biomineralogical studies and mathematical processing of results. Results. The conducted observations confirm the possibility of differentiated assessment of heavy metal contamination by the example of cadmium in the shelf Black Sea. Areas of pollution are characterized by a decrease in the species diversity of foraminifera compared to uncontaminated areas. In sediments with a high content of cadmium, foraminifera are characterized by depressed forms with numerous deformities. Conclusions. A significant concentration of cadmium strongly affects the occurrence of foraminifera and the appearance of morphological anomalies in their shells.

Considers modern geochemical characteristics of migration processes in pollution northwestern Black Sea shelf. Bulk precipitation suspension occurs on geochemical barriers "river-sea" or on the shelf outside the aver-age wave field. The main factor limiting the migration of solutes are the processes of biological absorption.Using cluster analysis, multidimensional establish substantial divergence component ratios depending on the time of observation. On the example of cadmium tendency to accumulate the most mobile of toxic components in the carbonate sediments of the shelf.
