“…The resistance of benthic hydrobionts to impact depends not only from the biological peculiarities of different species, but also from specific biotope, and composition of dredging material [5,6,[10][11][12][13][14][15].…”

“…In vitro experiments were conducted on the ability of benthic organisms to dig out the soil strata due to their periodic burying in process of dumping. Three most abundant groups of benthic communities of EGoF and Neva Bay were selected [1][2][3][4][5][6][7]. There were Chironomidae «bloodworms» Chironomus plumosus, Gastropoda mollusks (marine snails) Melanoides tuberculate, and Oligochaete Tubifex tubifex.…”

“…Burying under a sedimentary suspension of dredging material is the main type of impact on benthic communities in dumping areas and on the sites of dredged material deposits [1][2][3][4][5][6]. It is of great scientific and practical importance to estimate quantitatively the ability of individual benthic species and the bottom community as a whole to overcome this kind of anthropogenic stress.…”

The goal of the fulfilled research is the study of the influence of the sedimentary suspension from the dredging material on the benthic hydrobionts. In laboratory aquariums six series of experiments were carried out with triple replication on the ability of different benthic organisms to dig out the soil strata due to their periodic burying by marine sand. These experiments were oriented on biota of Eastern Gulf of Finland and the Neva Bay, where a number of deposit sites for dredging material are located presently. Representatives of three main groups of hydrobionts of these areas were selected for experiments – Chironomidae, Gastropoda and Oligochaeta. The ability of different hydrobiont species to overcome the stress effect of the burying under the dredged material was estimated quantitatively. The results show, that the resistance of the studied species to mechanical burying is decreasing in accordance to the scheme: Chironomus plumosus > Melanoides tuberculata > Tubifex tubifex, and depends from the thickness of the layer of dredged material.

“…In 1999-2019 the program of the Ecological Monitoring of Underwater Deposit Sites (EM UDS) for the Eastern Gulf of Finland and Neva Bay was developed and used [1][2][3][4][5][6][7][8][9]. Principal questions and goals of the EM UDS are: (1) revealing of the short-and long-term environmental effects of the dumping of the dredged material, and establishing the difference between the natural and anthropogenic trends of the coastal ecosystems near the dredged material deposit sites; (2) estimation of reversibility / irreversibility of trends and changes in coastal ecosystems due to influence of the dumping of dredged material; (3) finding the ways of minimizing and compensation of negative effects on the coastal environment [3,4,[10][11][12][13][14][15].…”

Long-term monitoring of the dredged material deposit sites in the Eastern Gulf of Finland

et al. 2020

The goal of the paper is summarizing the results of the 20-years monitoring of the deposit sites of the dredged material in the Eastern Gulf of Finland (EGoF) and in the Neva Bay. The biotic and abiotic components of deposit sites ecosystems were observed there in 1999-2019, with using standard monitoring methods, in order to reveal effects of dumping on hydrobiologic communities and to determine their environmental status. The Biota Condition Index for 6 deposit sites was calculated and compared to areas which are not stressed by dumping. It is shown that the biological communities (especially – benthic) in the deposit sites areas are enormous not-sustainable and start their succession from the zero point every time after repeating stressing effect of dumping.

“…Within environmental economics, an important aspect is the management of environmental risks during the implementation of large projects, for example, in the field of sustainable development of cities [1][2][3][4][5] and municipalities [6], or in the field of environmental management [7], including coastal zones [8], While such risk management we propose to use geo-information support [9][10][11], based on the principles of geoinformation management of complex geographically distributed systems [12][13][14][15][16][17]. If the projects are implemented in the Arctic and subarctic regions [18], the composition of natural risks must take into account climate change, due, inter alia, the influence of the inflow into the Arctic ocean of Pacific and Atlantic waters [19,20], the flow of Arctic rivers, as well as black carbon [21].…”

The paper presents the technologies of geoinformation support within hydraulic structures construction and exploitation at the stage of engineering-geological, engineering-ecological and engineering-hydrometeorological surveys for environmental economics during the implementation of major projects in the field of sustainable development of cities and municipalities. The impact of dredging on the natural environment is considered, and a conclusion about the need to study the rate of sedimentation at different stages of exploration, design, construction, and operation of underwater engineering facilities are made. It is shown how the construction of the Marine Facade of St. Petersburg for receiving tourist ferries changed the need for dredging volumes and how this affected the total cost of work. The port of Bronka in Neva Bay is used as an example of sedimentation study during the period of 2005-2007. The developed technologies should help in managing natural risks in the implementation of major projects in the field of construction and operation of hydraulic structures within the framework of the environmental economics in a changing climate.
