Sedimentary Matter

Using sediment traps (ST) in marine research expeditions from 1986 to 2010, 188 samples of suspended matter were analyzed. All the samples were received from the shallow-water area (2 to 50 meters depth) of the Black sea shelf. Sedimentary matter from the catch basins was singled out by means of direct, high vacuum, membranous ultrafiltration with nuclear filters having 0,45 μm diameter pinholes produced by the United Institute of Nuclear Investigations in Dubna (UINI). The suspended matter received was dried till weight stabilizing, scaled and underwent analytical research. The material composition of the sedimentary matter is represented by the clayed-carbonated-micaceous matter. Biogenous minerals are represented by three carbon types: tiff, aragonite and siderite. The amount of the chiselly biogenous minerals has a subordinate meaning and serves as adulteration in suspended matter. The amount of ore minerals in the suspended matter compositionreaches 2–3 % (ferric oxide – 1 %, ferric hydroxide – up to 2 %, etc.). Geochemical composition of the suspended matter is tightly related to the bioproduction and biofiltration, impact of river flow, shallow-water sediment detachment and inflow of aerosolized matter. The industrial factor plays an important part in formation of modern chemical suspended matter composition.

Research Problems

Analysis of the current state of marine research problems and formulate proposals for the establishment of a national system of sustainable development of marine research in Ukraine and ways of their implementation. Analysis of current problems in the marine research and respective national and international legal framework 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 presented. 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 importance 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.

National System

Purpose. Substantiation and formulation of conceptual basis to establish an effective National marine research system as a basic constituent of information support of Ukrainian economic and military interests in the Black and Azov Seas. Results. Current state of marine research infrastructures in Ukraine has been analysed, as well as the current legal framework. The issues of finding the ways to resolve the problem has been considered, first of all principles and mechanisms of an integrated system of marine studies restoration and functioning. Measures and steps have been substantiated to establish the National system of sustainable marine studies in Ukraine. The National system will be aimed at provision of the Government and the interested ministries and departments with up-to-date information for protection of National interests, enhancement of security, protection of sovereignty of the state. The list of concrete measures of the future programme has been presented and divided into three blocks: a) institutional, b) establishing of the up-to-date research infrastructure, c) performing of studies in the exclusive (marine) economic zone of Ukraine. Conclusions. Research potential of Ukraine has decreased during the past decade down to minimal critical level out of all the years since independence, first of all as the result of annexation of the Crimea and the adjacent Black Sea shelf area by Russian Federation. The departmental system of research financing and performing currently used in Ukrainian for goal-orientated marine studies in the interests of specific ministries and departments is unable to solve the existing problems. The only way out is to develop and implement a State target scientific and technical programme; its key priorities shall be solving of a number of similar international problems existing in all the Black Sea countries and the National interests of Ukraine. Establishing of a newest national research system is impossible without creation of a respective infrastructure, restoration of research fleet and an up-to-date system of marine specialists training taking into account the experience of European and world science.

The associations and ecological conditions of the existence of modern diatoms of the North-West (Pridneprovsky), Prikerchensky and Eastern regions of the subtidal zone of the Black Sea are considered. Based on the unity of the composition of the Present and Sarmatian-Meotian diatom flora, an attempt has been made to model some of the ecological c situation of the Late Miocene Euxinian basin.
