The article examines the influence of the Elga Coal Complex (ECC) on the hydrochemical state of surface waters. Open-pit mining of the Elga coal deposit takes place on the watershed of the Mulam and Algoma rivers, which are part of the hydrographic network of the Uchur river. During field work in 2012-2019, water samples for analysis were taken in two areas: on the right tributaries of the Algoma river and Bolshoye Toko Lake. Based on the analysis of selected samples, a new hydrochemical composition of water bodies was identified based on generally accepted methods in the Russian Federation. All samples had exceeded the maximum permissible concentrations for water bodies of fishery importance (MPCf), except for Lake Bolshoye Toko. The identified changes are presumably seasonal. In winter the flow on the tributaries of the Algoma and Mulam completely stops or decreases to vanishingly small values. To identify patterns in the formation of the qualitative state of water bodies in the zone affected by open-pit coal mining in permafrost conditions, further systematic observations are required until the planned production of high-quality coal oriented for export is achieved. The work was carried out within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation No. FWRS-2021-0014.

The materials of reports and publications on the seismogeological characteristics of the Anabar-Olenek structural zone, the shelves of the Laptev Sea and the East Siberian Sea have been studied. The work performed is aimed at clarifying, detailing and increasing the reliability of further research, previously updated in the process of scientific study of geological exploration materials of past years. The geological factors affecting the distribution of average and interval velocities of seismic reflection waves in the sedimentary cover are considered. For the entire territory, researchers have established an increase in reservoir and average velocities in the sedimentary cover as its thickness increases. This dependence is typical for the continental part of the platform. In the shelf deposits of the northern seas of Yakutia, the velocity dependence is determined by tectonic and magmatic factors, which become decisive for the Gakkel Ridge, Hyperborea, and the Novosibirsk-Chukotka structural zone. In the western part of the Laptev Sea, the surface of the consolidated crust corresponds to the surface of the Archean-Lower Proterozoic crystalline basement. In the rest of the territory, in the wave seismic field, the foundation is the asynchronous acoustic boundary of the surface of metamorphosed and dislocated strata with an age interval from the Riphean to the Paleogene. The observed complex wave pattern and various options for seismic reflector binding, in the opinion of the authors, are largely due to the structural and tectonic features of the evolution and interaction of the Siberian platform, Hyperborea, the Verkhoyansk-Kolyma folded region, the Arctic plume, the Novosibirsk-Chukotka structural-tectonic zone. The work was carried out with financial support within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation No. 122011100158-1 using the scientific equipment of the Center for Shared Use of the Federal Research Center ҺThe Yakut Scientific Centre of the Siberian Branch of the Russian Academy of Sciencesһ within the framework of grant No. 13.TsKP.21.0016.
