Comprehensive Study

Lake Baikal—a unique ecosystem on a global scale—is undoubtedly of great interest for a comprehensive study of its ecosystem. In recent years, one of the most significant sources of atmospheric pollution in the Baikal region was the emission of smoke aerosol and trace gases from forest fires, the number of which is increasing in the region. The transport and accumulation of aerosol and small gas impurities over water area of Lake Baikal is observed every summer due to forest fires occurring in the boreal forests of Siberia. The atmosphere above the lake covers a huge area (31,500 km2) and is still a little-studied object. This article presents the results of experimental studies of ground-level ozone, sulfur dioxide, and nitrogen oxides in the atmosphere over Lake Baikal, carried out on a research vessel during the boreal forest fires in Siberia in the summer of 2019.

The atmosphere over Lake Baikal covers a vast area (31,500 square meters) and has more significant differences in the composition and variability of gaseous and aerosol components in atmospheric air than in coastal continental areas and is still a poorly studied object. In recent years, the anthropogenic impact on the ecosystem of Lake Baikal has been increasing due to the development of industry in the region, the expansion of tourist infrastructure and recreational areas of the coastal zone of the lake. In addition, one of the significant sources of atmospheric pollution in the Baikal region is the emissions of smoke aerosol and trace gases from forest fires, the number of which is increasing in the region. This article presents the results of experimental studies of the dispersed composition of aerosols and gas impurities, such as ozone, sulfur dioxide, and nitrogen oxides during route ship measurements in the water area of Lake Baikal in the summer of 2020.

The paper presents the results of studies aimed at the analysis and assessment of atmospheric pollution over the Lake Baikal in the summer. This information is necessary to create physical models of the formation and transfer of atmospheric aerosol fields, taking into account the physical and geographical features of the Baikal region. Measurements were carried out by a lidar «LOSA-A2» installed on the scientific-research vessel «Academician V.A. Koptyug». The vessel’s route passed along the South, Middle and Northern Baikal, from July 15, 2018 to July 26, 2018. At the same time, observations were conducted using lidar «LOSA-M2». It was located in the background area at Boyarsky stationary site (51.84° N, 106.06° E), in the south-eastern part of the lake. The results of changes in the spatial structure of atmospheric aerosol fields in background conditions and during forest fires are shown.

Abstract. In June 2013, a ground-based mobile lidar performed the ~10 000 km ride from Paris to Ulan-Ude, near Lake Baikal, profiling for the first time aerosol optical properties all the way from western Europe to central Siberia. The instrument was equipped with N2-Raman and depolarization channels that enabled an optical speciation of aerosols in the low and middle troposphere. The extinction-to-backscatter ratio (also called lidar ratio or LR) and particle depolarization ratio (PDR) at 355 nm have been retrieved. The LR in the lower boundary layer (300–700 m) was found to be 63 ± 17 sr on average during the campaign with a distribution slightly skewed toward higher values that peaks between 50 and 55 sr. Although the difference is small, PDR values observed in Russian cities (>2%, except after rain) are systematically higher than the ones measured in Europe (<1%), which is probably an effect of the lifting of terrigenous aerosols by traffic on roads. Biomass burning layers from grassland or/and forest fires in southern Russia exhibit LR values ranging from 65 to 107 sr and from 3 to 4% for the PDR. During the route, desert dust aerosols originating from the Caspian and Aral seas regions were characterized for the first time, with a LR (PDR) of 43 ± 14 sr (23 ± 2%) for pure dust. The lidar observations also showed that this dust event extended over 2300 km and lasted for ~6 days. Measurements from the Moderate Resolution Imaging Spectrometer (MODIS) show that our results are comparable in terms of aerosol optical thickness (between 0.05 and 0.40 at 355 nm) with the mean aerosol load encountered throughout our route.

This paper is devoted to the unique water body, Lake Baikal, the largest freshwater reservoir by volume in the world that was included on the list of UNESCO World Heritage Sites and is regulated by the federal law of its protection. The global role of Baikal as a strategic reserve of water resources of the highest class is increasing in importance. Furthermore, Lake Baikal and its surroundings are invariably the focus of ecological problems. The most challenging issues are the lake’s water pollution leading to changes in hydrobiocenoses, soil and vegetation digression in areas of increased recreational load, forest fires causing a decrease of the number of rare species of flora and fauna, etc. Imperfection of the legal framework, the lack of a unified managerial center and the attempts to deal with the problems solely at the federal level involve a number of incompetent decisions on the lake level regulation and on the setting of its water-protection zone. The conflicts of the interests of the subjects of the federal and regional levels in issues related to use and the protection of natural resources present serious obstacles to the development of a unified, ecologically oriented strategy of economic development of the territory. For a successful solution of the current challenges it is necessary to recognize the ecological problems of Lake Baikal as the priority concerns throughout the country, optimize management of the socio-economic development of the Baikal natural territory on the basis of nature-conservation principles by ensuring appropriate funding, develop a unified scheme of comprehensive monitoring of the ecological and sanitary-hygienic status of Lake Baikal and its protection zone, improve the system of scientific research on the Baikal natural territory, introduction ubiquitous ecological training and education of the population, organize the waste and effluent treatment system in accordance with the latest international technologies, etc.

This article is devoted to the development of a monitoring system of Lake Baikal. The developed system should provide ongoing monitoring of hydrophysical parameters of water in different areas of the lake, which will allow identifying signs of environmental pollution of Lake Baikal timely. A distinctive feature of the created system is high productivity at low economic costs per accounting point. The appropriate selection of the component base and software optimization of algorithms will allow achieving the maximum range of data transmission at a distance of up to 100 km in an open area. The interim results of the monitoring system development are presented, the tasks for the current year are defined.

The research estimated the water surface area and volume of the fishing bay Proval in Lake Baikal by using the QGIS and SAGA geographic information systems. Such characteristics are used by ichthyologists to assess the reception capacity of the water area. Additionally, we considered the cases when the water level drops by 0.6 and 1.2 meters. The results may be used to predict population size of Baikal omul in low-water periods.
