The distribution of dissolved chemical elements (major ions, nutrients, and trace elements) in the Yenisei River estuary and adjacent water area in 2009 and 2010 are presented. These results were compared to the data obtained during previous hydrochemical studies of this region. The transport of major cations (Na, K, Mg, Ca) and some trace elements (Rb, Cs, Sr, B, F, As, Mo, U) in the estuary follows conservative mixing. Alkalinity also belongs to conservative components, however this parameter exhibits substantial spatial heterogeneity caused by complex hydrological structure of the Yenisei Bay and adjoining part of the Kara Sea formed under the influence of several sources of desalination and salty waters inflow. Concentrations of Pmin, Si, and V in the desalinized waters of photic layer decrease seaward owing to uptake by phytoplankton. The losses of these elements reach 30–57, 30, and 9% of their supply by river runoff, respectively. The content of dissolved phosphates and vanadium in the intermediate and near-bottom layers of the Yenisei River estuary strongly increases with salinity due to regeneration of precipitated organic matter, whereas silica remineralization is much less pronounced. Barium is characterized by additional input of dissolved forms in the mixing zone in the quantity comparable to that carried out by river runoff. This may be caused by its desorption from river suspended matter due to ion exchange. The transport of dissolved Al and Mn in the estuarine zone is probably controlled by the coagulation and flocculation of organic and organomineral colloids, which is indicated by a decrease in the concentration of these elements at the beginning of the estuary (31 and 56%, respectively) followed by a stable concentration further seaward.

Рассматривается состояние эндемичных байкальских амфипод в р. Енисей, приводятся результаты экспедиционных исследований. Отмечается факт многоразового увеличения количества амфипод в Енисее после зарегулирования плотиной Красноярской ГЭС. Данные гидробиологического мониторинга оформлены в виде геопространственной базы данных на геопортале, который предоставляет возможности визуализации результатов исследований в виде интерактивных тематических карт, прямого доступа к данным через картографические веб-сервисы из современных ГИС. The purpose. The purpose of the work is the theoretical and practical studies of the possibilities for using the geoinformation web-system modern technologies for improving the efficiency of hydrobiological monitoring, and design of software tools of data presentation and analysis for field research. Methods. The technologies for development of distributed information systems in multi-tier architecture, along with software interfaces and protocols, information exchange standards are considered. The possibilities for using of geoinformation and cartographic modelling methods for searching the relationship between the spatial distributions of Baikal amphipods in the Yenisei river with different environmental factors are investigated. Results. The technologies and related software are developed for the considered problem. The geospatial database is generated and filled with the results of own longterm hydrobiological field studies, it has become an integral part of the geoportal of ICM SB RAS, which was formed by the separate thematic section. The focus is on the results of extensive field studies of the Yenisei implemented in 2015 and 2016. As to database content, the information about the quantitative distribution of zoobenthos (animals inhabiting the ponds bottom), in particular endemic Baikal amphipods, in the area from Yenisei river headwaters to its delta was used. It was revealed that the amphipods — the endemics of the Baikal lake — spread far beyond its limits not only downward, but also upstream the Yenisei river. After the commissioning of the Krasnoyarsk hydroelectric power station, their share in the total zoobenthos biomass is increased by 10 times. Gmelinoides fasciatus crustacean is especially active; it has massively populated the area of the Upper Yenisei river below the Sayano-Shushensky reservoir. The density and the fraction of crustaceans in the zoobenthos in the area of the Angara — Podkamennaya Tunguska has increased over the last 15 years. Conclusions. Creation of a geospatial database alongside with the results of expeditionary research and the introduction of a GIS web-system for information-analytical support of hydrobiological monitoring significantly expands opportunities for the analysis and presentation of geodata, forms the basis for interdisciplinary research.
