The Impact

The methodology for developing a web version of the Electronic Ecological Atlas of the Sea of Azov is based on the use of “cloud” technology of the geoportal — an open platform that is completely built on world industry standards and supports various types of data and services. In 2019, the static part of the Ecological Atlas of the Sea of Azov (Atlas) was completed and posted on the organization’s website, based on the use of standard website creation methods. The objective of the study is to expand the standard means of presenting Atlas data by introducing interactive web applications into it. Web applications are developed on the ArcGis Online platform using Esri standards. As part of the development of the dynamic part of the Atlas, two interactive web applications were created: “Ecological study of the seas of the south of Russia” and “Water Protection Zone of the Sea of Azov”. The application “Ecological study of the seas of the south of Russia” includes thematic maps built on the basis of interactive queries, including maps of the distribution of observation stations by year, by executors and type of observation, as well as infographics and data tables. The web application allows you to create maps that clearly show the results of field research and measurements in the Azov Sea region, as well as allow visual analysis of data from different years, add your own tabular relationships. The purpose of the application developed “Water protection zone of the Azov Sea” is the empowerment of the Atlas through the introduction of interactive web applications tightly themed. One of the objectives is to assess the impact of economic activity on the coastal zone of the Sea of Azov within the water protection zone.

The distribution and behavior of certain of trace elements in sea water is greatly affected by both physical, chemical and hydrometeorological conditions that are showed in the scientific works of prof. Yu.A. Fedorov with coauthors (1999-2015). Due to the shallow waters last factor is one of the dominant, during the different wind situation changes significantly the dynamics of water masses and interaction in the system “water – suspended matter – bottom sediments”.Therefore, the study of the behavior of the total iron in the water of the sea at different wind situation is relevant. The content of dissolved iron forms migration in The Sea of Azov water (open area) varies from 0.017 to 0.21 mg /dm3 (mean 0.053 mg /dm3) and in Taganrog Bay from 0.035 to 0.58 mg /dm3 (mean 0.11 mg /dm3) and it is not depending on weather conditions.The reduction in the overall iron concentration in the direction of the Taganrog Bay → The Sea of Azov (open area) is observed on average more than twice. The dissolved iron content exceeding TLV levels and their frequency of occurrence in the estuary, respectively, were higher compared with The Sea of Azov (open area).There is an increase in the overall iron concentration in the water of the Azov Sea on average 1.5 times during the storm conditions, due to the destruction of the structure of the upper layer and resuspension of bottom sediments, intensifying the transition of iron compounds in the solution.

The article analyzes the three stages of the migration of the German ethnic group into the territory of modern Ukraine, different in nature, character and orientation, and their features are clarified. The author reveals the geography of the first migratory flows of the Goths in the second half of the II century, which went from the Wisla delta to Scythia, and were divided into the western (settled on the right bank of the Dnieper) and eastern. The latter, having settled down near the Sea of Azov, founded the state of Germanarich, and in the IV century, under the pressure of the Huns, the center of life of Goths moved to the Kerch Peninsula, the mountainous region of Crimea, where their state association Gothia existed until the XVIII century. It turns out that in the early Middle Ages there was a second wave of German settlements on modern Ukrainian lands from the West European direction. The expansion of the settlements of Germans and immigrants from other European countries on the lands of Kievan Rus was facilitated by political relations, which were also realized with the help of dynastic marriage unions. The princes of Kiev, pursuing a foreign policy worthy of a great power, have equal relations with the main European states of the medieval world - the Holy Roman Empire (Germany) and Byzantium, they invite priests, German craftsmen and merchants. Starting from the XI century, small German trade colonies appeared in Kiev, Vladimir-Volynsky, Lutsk and other cities. During the Lithuanian-Polish period, the influx of German settlers to Ukrainian lands is increasing. This was facilitated by various benefits and provision of points to the German immigrants by Lithuanian princes and Polish kings. In the fourteenth and fifteenth centuries, Magdeburg law was acquired by large trading cities. The third period, the most significant resettlement and colonization, that is, large-scale development of the South of Ukraine - the Sea of Azov, the Black Sea region and the lands of Crimea - begins in the second half - the end of the 18th century. The author emphasizes that this most powerful period and the great positive history of the development of our region is largely connected with immigrants of German origin (and representatives of other ethnic groups). This period becomes a powerful colonization and economic development of the entire South of Ukraine, the rich land of the Azov, Black Sea, Crimea. It is noted that then, on the initiative and real support of the government of tsarist Russia, the development of wide steppe spaces took place, which, together with Ukrainian lands, had recently been transferred to the Russian Empire. Since then, the history of immigrants has become part of the history of the Ukrainian people. The dynamics of the development of German colonies in different provinces of the South of Russia is analyzed separately, the social aspects of the life of settlements, the grave consequences for the colonists associated with the First World War, and revolutionary events in the Russian Empire are indicated. The gains and losses in the national development, in the arrangement, in the administrative division of the German and other settlers, which were the consequences of radical fluctuations in the national policy of the Soviet government in the pre-war period, are revealed.

<p>Loess-palaeosol sequences are the most intensively studied terrestrial archives used for the reconstruction of late Pleistocene environmental and climatic changes in the Sea of Azov region, southwest Russia. Here we present a revised luminescence-based chronostratigraphy and a multi-proxy record of late Pleistocene environmental dynamics of the most complete and representative loess-palaeosol sequences (Beglitsa and Chumbur-Kosa sections) from the Azov Sea region. We propose a new chronostratigraphy following the Chinese and Danubean loess stratigraphy models that refines the subdivision of the last interglacial palaeosol (S1) in two Azov Sea sites, resolves the uncertainty of the stratigraphic position of the weakly developed paleosol (L1SSm) in Beglitsa section, and allows direct correlation of the Azov Sea sections with those in the Danube Basin and the Chinese Loess Plateau. More importantly, it adds important data to better constrain local and regional chronostratigraphic correlations, and facilitates the interpretation of climatic connections and possible forcing mechanisms responsible for the climatic trend among these regions. In addition, a general succession of environmental dynamics is reconstructed from these two vital sections, which is broadly consistent with other loess records in the Dnieper Lowland and Lower Danube Basin, demonstrating similar climatic trends in these regions at glacial-interglacial time scales. However, differences in details were also identified, especially for palaeosols developed during the last interglacial period, and the cause of these dissimilarities between loess records appears complex.</p><p>Furthermore, our results have important implications for the chronostratigraphic representativeness of Beglitsa as a key loess section and the reconstruction of the temporal and spatial evolution of late Pleistocene palaeoclimate in the Sea of Azov region.</p><p> </p>

The Impact

The Etang-de-Berre area is a large industrialized area in the South of France, exposing 300,000 inhabitants to the plumes of its industries. The possible associated health risks are of the highest concern to the population, who asked for studies investigating their health status. A geographical ecological study based on standardized hospitalizations ratios for cancer, cardiovascular, and respiratory diseases was carried out over the 2004–2007 period. Exposure to air pollution was assessed using dispersion models coupled with a geographic information system to estimate an annual mean concentration of sulfur dioxide (SO2) for each district. Results showed an excess risk of hospitalization for myocardial infarction in women living in districts with medium or high SO2exposure, respectively, 38% [CI 95% 4 : 83] and 54% [14 : 110] greater than women living in districts at the reference level exposure. A 26% [2 : 57] excess risk of hospitalization for myocardial infarction was also observed in men living in districts with high SO2levels. No excess risk of hospitalization for respiratory diseases or for cancer was observed, except for acute leukemia in men only. Results illustrate the impact of industrial air pollution on the cardiovascular system and call for an improvement of the air quality in the area.

The ice regime of the Sea of Azov over the period of 20th and 21nd centuries was investigated using the author's GIS «The ice regime of the Southern Seas of the Russia». The long-term dynamics of the ice cover, duration of the ice stay as well as beginning and end of the ice period were considered. It has been found that for the period of 1950–2015 the average annual value of the Azov Sea ice cover area is 33%, while the average area of the fast ice is 6.3% of the total area of the sea. Value of duration of the ice cover stay on the sea surface has been refined, and this value is 115 days near the hydro-meteorological station (HMS) Taganrog and 63 days near the HMS Kerch. The typification of winters according to the degree of severity was performed on the basis of data from three coastal meteorological stations: Taganrog, Genichesk, and Kerch. Winters of moderate type were shown to be prevailing during the entire analyzed period. Totally, 15 severe, 70 moderate and 40 mild winters were isolated for the period 1883-2015, while for 1950–2015 the statistics was the following: 9 severe, 43 moderate, and 14 mild winters in Taganrog, and 10 severe, 40 moderate, and 16 mild winters in Kerch.

The Impact

Coastal zones are integral natural and socio-economic territorial-water system, combined by a complex structure of interactions. Coastal geosystems are unique, rich in natural resources, which determines their attractiveness for industrial and residential, recreational, transport and other activities, but also makes them environmentally vulnerable. Sustainable development of the coastal zone is determined by the economic, social, and environmental components. The research area of interest is the coastal zone of the Sea of Azov (Rostov Region). The subject of the study is the state of medical and environmental safety of the territories. The purpose of the study is the analysis of medical-ecological and socio-demographic factors as the basis for sustainable development of the coastal zone of the Sea of Azov. A systematic approach has been implemented to assess the sustainable development of the coastal zone and to develop methods for analyzing and integrating heterogeneous data. Changes in the coastal zone were evaluated based on a comparative analysis of multizone satellite imagery with ground-based studies, data from thematic maps. For the analysis of medical and environmental safety, an author’s technique was used, combining traditional methods and geoinformation technologies based on ArcGis Desktop*. The environmental quality indicator was considered in terms of the impact on human health. Assessment of demographic security was carried out based on the coefficient of demographic well-being / prosperity of the territory. The incidence rate of malignant neoplasms was considered as a highly informative and socially significant indicator of the health status of the population. For analysis, we used the SSC RAS database for 2006-2016. A comprehensive analysis of the development factors of the coastal zone of the Sea of Azov showed significant problems in the studied region. The most attractive areas of the coastal zone of the Sea of Azov from the point of view of infrastructure development are at the same time subject to changes due to dangerous natural phenomena. Analysis of demographic indicators confirmed the presence of adverse demographic processes.

The Impact

The purpose of this work is to comprehensively study the ecological and geological conditions and the results of monitoring studies of the coastal territories of the Taganrog Bay and the Sea of Azov to identify the degree of manifestation of dangerous coastal processes (DCP). The subject of the study is to assess the degree of manifestation of DCP under the influence of various natural factors, both constant in time (geological structure, height of the coastal cliff), and changing (dynamics of the level, waves, wind regime) and the impact of man-made causes. The performed factor analysis allows us to assert that the main natural factor of the intensification of DCP is the extreme surge levels (adverse end dangerous events: AE and DE). The types of shores are constant, but with different degrees of manifestation of DCP, they change significantly. As a result, according to these studies, maps were constructed for the average long-term (1980), intensive manifestation (2013–2014) and the period with a relatively calm manifestation of the intensity of DCP (2018–2020). According to the activity, the manifestations of DCP are divided into 4 types: type I – with a very high c (>4 m/year), type II – with a high (2–4 m/year), type III – with an average (1–2 m/year), type IV – with a weak rate (<1 m/year) of abrasions, which include subtypes of banks formed by exogenous processes (abrasive, abrasive-landslide, accumulative), indicating the conditions of their formation and the reasons for the isolation of the danger of coastal processes.

Oceanographic Data

One of the most demanded directions of oceanographic problems is the study of long-term variability and modeling of future climatic changes and also the possibility of obtaining continuous information on the thermohaline structure of the sea based on the joint use of remote sensing data and the results of assimilation modeling. In current paper, research, of the Sea of Azov for the period 1913–2018 was carried out. We used the data of contact measurements from the oceanographic data base of the SSC RAS, Atlas of climate change in large marine ecosystems of the Northern Hemisphere, as well as data from the oceanographic data bank of the Marine Hydrophysical Institute RAS. Based on the analysis of the information, the calculation of the average monthly temperature and salinity was carried out, the periods of anomalous temperature were revealed, the periods of salinization and desalination of the Azov Sea also were noted. Data analysis made possibility to identify intrasecular climate fluctuations. Abnormally cold water temperature in winter was noted in the periods: 1926–1932, 1951– 1956, 2003–2012. In turn, the abnormally warm water temperature in winter, which was recorded in the periods: 1935–1939, 1958–1972, 1983–1992. by accompanied a cold spring-summer period. During the last five years the spring-summer period is characterized by an increased water temperature of the Azov Sea. The long-term variability of the salinity of the Sea of Azov significantly depends on the inflow of saltier waters of the Black Sea and river runoff. Due to these circumstances, the Sea of Azov is characterized by periods of salinization and desalination: the period of salinization was recorded from 1955 to 1973, a shorter period of desalination falls on 2003–2018. On average, the value of the ratio between the mean monthly salinity values during these periods is 2,2 times.
