Rational use of nature, solution of natural and environmental problems, planning and location of various sectors of the economy are based on climatological information. As empirical data accumulate, some values, as well as the probabilistic characteristics of climate-relatednatural resources, need constant refinement due to the fact that hydrometeorological phenomena are extremely variable in time and space. Of great practical interest is information on daily and maximum rainfall and therefore there is a need for their comprehensive analysis, study and forecasting.\u0000Data & Methods. The initial information for estimating the precipitation regime is the term data for 00, 06, 12 and 18 hours at nine stations of Odessa region in the period 2010–2015, to which a number of general scientific and statistical methods were applied.\u0000Results. Some indicators of the precipitation regime, which are widely used in scientific and practical developments, are analyzed. The total number of days with precipitation and their recurrence are determined. For the territory of the region it is 34.4%. The most days with precipitation were observed in January, and the least – in August, except for Art. Calm, at which the minimum number of days with precipitation was recorded in November. The frequency of precipitation of different gradations was studied and significant precipitations were analyzed: 10, 20, 30 mm and more per day. The region is dominated by precipitation up to 10.0 mm, the frequency of which ranges from 86% (station Rozdilna) to 91.4% (station Odessa). The maximum frequency of days with precipitation of 30 mm or more per day falls on the warm season (April-October). The fields of daily maximum of 1% and 5% probability are heterogeneous and at some stations of Odessa region the values of this indicator exceed the climatic norm (up to 10–12 mm), at others – less than the norm. The obtained results are a certain contribution to the study of both theoretical and practical aspects of the study of daily amounts and daily maximum precipitation, which are indicators of the regional climate. They can be used to make a climatological forecast, which is necessary for a more complete development of climatic resources of Odessa region.","PeriodicalId":398162,"journal":{"name":"Odesa National University Herald.

Approaches, principles and methods of research of anthropogenic landscapes, in particular landscape-technical systems, are considered in detail in the works of many scientists. However, less attention is paid to the study of water management landscape technical systems. This necessitates more specific approaches, principles and methods that would allow to fully reveal the essence of these systems. Water management landscape-technical system is a complex system that combinesnatural, technical and information blocks that interact with each other. Therefore, researching these systems, in addition to traditional and specific, it is necessary to use at the integrated level the principles and methods of various natural sciences.\u0000Data & Methods. In the process of analysis and disclosure of approaches, principles and methods of research of water management landscape system, the following methods were used: structural and logical generalization (used to identify traditional methods in the study of the system), abstraction (selection of specific methods to reveal the essence of the system), system analysis (establishment of integration links between traditional and specific methods of scientific cognition), generalization (made it possible on the basis of the obtained data on methods of scientific cognition to develop a scheme for studying the water landscape system of the Trubizh river basin).\u0000Results. It is noted that the study of water management landscape technical system is impossible without the use of a systematic approach, which is traditional in all theoretical studies. Approaches that help to reveal the essence of the water management landscape and technical system (historical, basinal, system, paragenetic, constructive, cartographic and geoinformational) are identified and analyzed. The cartographic approach is singled out, which is one of the main ones in the study of water management landscape technical systems. There is a particular emphasis on the geoinformational approach, as the development of GIS projects is one of the most promising and modern trends in the study of not only water management landscape and technical systems, but also anthropogenic landscape science in general. The essence of specific principles and research methods is revealed, as they help to understand the peculiarities of the water management landscape and technical system. Three basic principles (historicism, natural anthropogenic compatibility and advanced study of previous natural and anthropogenic landscapes) were considered, on their basis seven methods of scientific research were identified and analyzed.

In geological surveys of the territory of the Moldavian SSR from the 1960th to the 1990th, deep horizons of Palaeozoic sedimentary rocks were discovered, the leading place among which belongs to the Silurian deposits. At that time, several dozen species and genera of fossils were identified in the Silurian of Moldavian Pridnestrovye. In 2020, as part of the work financed from the state budget on the theme of the creation of GIS “The Geology of Pridnestrovye”, the laboratory “The Geological Resources” developed an electronic database called “The Palaeontology of Pridnestrovye”. The fauna included in the database of palaeontology was divided into groups corresponding to their palaeontological classes and stratigraphic horizons: “Ordovician brachiopods”, “Silurian tabulates”, “Palaeogene foraminifers”, “Neogene bivalves”, etc. Species and genera of the fauna were linked to specific formations and locations, which provides good opportunity for palaeontological analysis of individual formations, horizons, cores of drilling and outcrops. The purpose of this article is to compile lists of fauna from the Llandoverian and Wenlockian formations of Moldavian Pridnestrovye and to compare their chronology with fossil fauna data on the sameage rocks of Podillia, Estonia and Lithuania.\u0000Material and methods. Four survey reports deal that on sheets L‑35-V and L‑35-XII were used as the material. The goal was concerning the sedimentary rocks of Llandovery and Wenlock Series. In the local scheme it corresponds to the Marasesti, Step-Soci, Cioc-Maidan (all in Llandovery), Balti formations and Lower Puhoi subformation (Wenlock). The intervals of the formations in boreholes are composed of organogenic limestones, silty, argillaceous stones, argillites and dolomites. The species and genera of the fauna from these intervals are compared with the biostratigraphic data from Podillia, Estonia and Lithuania.\u0000Results. In the stratigraphic sequences of Llandovery and Wenlock of the Moldavian Pridnestrovye, (in most cases) species and genera unique to those divisions of brachiopods, tabulates, stromatoporoids, ostracods, rugosans, and trilobites were identified by specialists; a smaller part of the taxa pass between the lowest formations of the Silurian and the overlying Balti formation. Most taxa have correspondences in the Podillian and Baltic basins; however, in these regions, the species and genera identified in Llandovery or Wenlock of Moldavian Pridnestrovye are mostly transitive between Silurian divisions, up to the Ludlow and Pridoli Series.

The Lower Dniester delta and the Dniester estuary are very important because they are natural filters of the river water from pollution and suspended matter, as well as they are the habitat of a large number species of flora and fauna. The construction of reservoirs on the Dniester River in past completely changed the hydrological regime of the river itself and of the Dniester estuary. For these reasons a constant environmental monitoring of the aquatic environment are required. Since 2002 Odessa I. I. Mechnikov National University has been carrying out a wide range of environmental studies in the Dniester estuary, one of aspects of which is observation of hydrological characteristics. The purpose of this paper is to study long-term changes in transparency, temperature and electrical conductivity of the Dniester estuary water in the summer periods of 2003–2019.\u0000Materials & Methods. Measurements of transparency, temperature and electrical conductivity of water in the Dniester estuary in the indicated years were carried out according to standard methods at 19 ecological stations. Statistical processing, analysis and mapping of the measurements results were conducted in EXCEL, ARCGIS, SURFER software’s. Data analysis was based on a graphical representation of the spatial distribution of characteristics, as well as by identifying the features of long-term changes in these characteristics.\u0000Main Results and Conclusions. On the basis of the summer surveys during 2003–2019 more than double decrease of water transparency mean values in the Dniester estuary has been established. It was found that the maximum transparency values were observed in the central parts of the estuary, far from settlements. For theseyears, an increase of the mean water temperature for the estuary northern part and its decrease in the middle and southern parts has been recorded. Also, for the summer period of these years, an increase of the mean water electrical conductivity in all parts of the estuary was established. The established features of spatial distribution of hydrological characteristics indicate to the river runoff, intrusion of seawater into the estuary, and wind activity as the determining factors in formation of the estuary hydrological regime. Recorded long-term trends of the means transparency values decreasing and the means temperature and electrical conductivity increasing of the Dniester estuary water in the summer of 2003–2019 are considered as consequences of the river discharge decreasing due to long-term climatic changes over Europe and man regulation of river flow.","PeriodicalId":398162,"journal":{"name":"Odesa National University Herald.

In Transnistria, the deposits of Sarmatian-age limestone are explored and exploited. These minerals are used as raw materials for cement production, as well as for the production of buta and rubble. The issues of genesis and facial transitions of these deposits remain under-studied.\u0000Data & Methods. The purpose of this work is to determine the genetic affiliation of the limestone deposits of the Gidirim and Severin deposits on the basis of facial and chemical analysis. The materials of the research are the limestones of two deposits of Transnistria. The object is the limestone of the Sarmatian age of the deposits of Transnistria. The subject of the study is the lithological and paleontological characteristic, the chemical composition of these limestones. Research methods: topical; biofacial, computer processing with GIS – programs; Laboratory quality diagnostics, chemical and physical-chemical methods of quantifying the main components of carbonate rocks.\u0000Results. The geological conditions of the Severin and Gidirim deposits were studied, and the place of productive layers of deposits in the stratigraphic scheme of Transnistria was determined on the basis of the lithological and paleontological characteristics of the rocks. Limestones mined at the Gidirim field belong to the May Day retinue, and the limestone of Severinovsky belongs to the Bessarabian reefs. Chemical analysis of limestone samples extracted from the deposits was carried out and differences in the chemical composition of the limestone of these deposits were determined. The limestone deposits in the content of calcium carbonate are clean. The concentration of silicon dioxide in the samples of the Severin field is higher than in the samples of the Giderim field, the content of one-and-a-half oxides, on the contrary, in Severinovka – 0.68%, in samples of the Giderim field – 1.04%. Analysis of the lithological composition and fauna of limestones has made it possible to distinguish within the Middle-Sarmatian basin of sedimentopulation: (a) accumulation of biogenic-chemogenic limestone of the near shelf, b) biogenic precipitation of the transition zone (reefs), c) silicate-terrigenous formations of the far shelf. The variety of phased conditions in the basin is associated with the position of the coastline and the inflection of the bottom on the boundary of the near and far shelf. The limestone of the studied deposits was formed in two different facial environments: the chemogenic-carbonate and the transient, which is associated with the formation of a strip of Bessarabian reefs. The study of paleontological residues, lithology and chemical composition of rhypogenic limestone showed the autonomy of this environment, as it has features of sedimentogenesis and near and far shelf.","PeriodicalId":398162,"journal":{"name":"Odesa National University Herald.

The study area encompassing the territory of about 150 km2, in August 2000, was declared as a zone of environmental emergency due to increasing pollution rates in shallow groundwater, in surface water and to health deterioration of the inhabitants of some settlements. Groundwater is widely used by the local population in numerous boreholes for domestic and agricultural purposes. In the zone of environmental emergency there are about 35 anthropogenic objects, such as: industrial and domestic landfills, pesticide and fertilizer storage, various livestock farm complexes, settling tanks, wastewater and solid waste discharges, etc. The insecurity of shallow groundwater, also its location close to the surface and in the lowest parts of the terrain leads to intensive pollution of groundwater. Besides, groundwater in relation to the fractured waters of the Precambrian crystalline rocks, which lie below and are used for drinking water supply, perform the functions of both a protective screen and a source of pollution. In this case, a multifaceted study of shallow groundwater chemical composition and their formation conditions is a priority task of this study for the environmental emergency zone and for the district as a whole.

A total of 102 water samples were collected from groundwater wells and boreholes and were hydrochemically analyzed for their macrocomponent composition. Groundwater quality geochemical assessment was carried out using statistical methods in combination with conventional graphical methods by examining groundwater in the Boleslavchik village, where they are most polluted.\u0000Results. The dominant hydrochemical types of shallow groundwater are SO4- Na, HCO3-Na and mixed SO4-Mg-Na, SO4-Ca-Na types, sometimes NO3-HCO3 and NO3-Cl-Na types. These groundwater types are formed under the influence of natural and anthropogenic factors, such as water-rock interaction, evaporation-crystallization, precipitation and anthropogenic impact. In this case, water-rock interaction processes, such as silicate weathering, carbonate and sulfate dissolution, ion exchange, evaporation-crystallization and anthropogenic impact play major roles. The weathering of feldspars, chlorites and dissolution of calcites, dolomites are the primary sources for Na+, K+, Mg2+, Ca2+ ions, and dissolution of gypsum, sulfide mineralization for SO4 2– ions. High concentrations of Na+, Cl–, SO4 2–, NO3 – in shallow groundwater reflect agricultural activity as the main source of these ions.","PeriodicalId":398162,"journal":{"name":"Odesa National University Herald.
