Ensuring environmental safety in the Arctic, where most large hydrocarbon deposits are concentrated, is one of the main problems of the 21st century. At the same time, the Gulf of Ob is a strategically important area where grandiose energy resource and transport projects are being implemented. An important indicator of environmental safety is the research of atmospheric impurities on the surface of the large bay of the Kara Sea, which has not been sufficiently studied to date. The purpose of the research is to assess the impact of the activities of the fuel and energy complex on the ecological state of the waters of the Gulf of Ob for 2016-2020 using geographic information systems. The Earth program was used in the research; statistical processing of the results was carried out using IBM SPSS Statistics 21 software. It has been established that in the winter period of the year, in contrast to the summer, on the surface of the water area of the Gulf of Ob there is a significant increase in the concentration of gaseous impurities and a decrease in suspended particles, especially over the water area of the Gulf of Ob at the northern latitude of 68.80º an area of intensive gas production. Moreover, in the summer, the content of suspended particles (PM1, PM2.5, PM10), as well as the CO concentration at this latitude were higher compared to the more northern latitude. Thus, the intensive development of the fuel and energy complex in this region is associated with an environmental component (carbon footprint) on the surface of the Gulf of Ob, which requires a more in-depth research within the carbon polygon.

The article highlights the sea factor and maritime economic activity to influence regional socio-economic development, as the issue is extremely topical for modern Russian socio-economic geography. It is shown that such influence has increased significantly since the middle of the XX century. The special attention is focused on identifying the features and spatial localization factors of maritime economy’s components in the Russian Federation. Such characteristics of the geography of the marine economy inherent in Russia as spatial asymmetry, gravitation to the border territories and water areas of the country, cross-border nature are highlighted. The study identifi the maritime economic specializations of the seaside regions and their carried out the corresponding typology (given the degree of infl of the«marine factor»). The article emphasizes the combination of spatial dispersal of marine activity (in such spheres as port economy, shipbuilding, hydrocarbon production) inherent in modern Russia (and initiated by Eurasian geopolitical and economic changes) with the remaining stable regional asymmetry in the localization and development of fi as well as in the tourism and recreational sphere. The article shows that the positive socio-economic effects of marine industries’ development are most pronounced in the regions and cities that perform the ‘frame’ functions in the system of geo-economic positioning of Russia, as well as in ensuring the ‘presence’ of the country in the World Ocean. These ‘frame’ regions are: St. Petersburg and Leningrad region, Krasnodar region, Primorsky region, Sakhalin region, etc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
