The Impact

Abstract Aerial surveys of coastal habitats can uniquely inform the science and management of shallow, coastal zones, and when repeated annually, they reveal changes that are otherwise difficult to assess from ground-based surveys. This paper reviews the utility of a long-term (1984–present) annual aerial monitoring program for submersed aquatic vegetation (SAV) in Chesapeake Bay, its tidal tributaries, and nearby Atlantic coastal bays, USA. We present a series of applications that highlight the program’s importance in assessing anthropogenic impacts, gauging water quality status and trends, establishing and evaluating restoration goals, and understanding the impact of commercial fishing practices on benthic habitats. These examples demonstrate how periodically quantifying coverage of this important foundational habitat answers basic research questions locally, as well as globally, and provides essential information to resource managers. New technologies are enabling more frequent and accurate aerial surveys at greater spatial resolution and lower cost. These advances will support efforts to extend the applications described here to similar issues in other areas.

The article describes the purpose of the work, which is determining the distribution and relationships between the composition of pollutants in coastal soil, bottom sediments and higher aquatic vegetation in the small river Khodtsa. There have been presented the data of the laboratory research based on the results of the field work onselecting samples, on concentration of toxicants (cadmium, lead, iron, nitrogen, ammonium and petroleum products) in deposit media, as well as in Carex aquatilis plants of the small river Hodza. This plant species is limiting throughout the river due to the low intensity of biological absorption. The studies were carried out during the summer low water season in 2019 on the river section from the source (Elektrostal city) to the river mouth in the area of Pavlovsky Posad. In all the studied objects there have been found increased concentrations of iron. In the coastal ground and bottom sediments the pollution with heavy metals is manifested to a much greater extent: at the source and intermediate point. Petroleum products and ammonia nitrogen are distributed unevenly in space. A correlation analysis of the experimental data obtained in the components of the environment of the studied territory (the Khodtsa river) was performed. In general, the highest measurement results are observed in the upper reaches of the small river Khodtsa in the industrial city of Elektrostal. The obtained data on the heavy metals migration in the system “сoastal ground – bottom sediments – higher aquatic vegetation” of the small river Khodtsa can be successfully used as indicators an environmental monitoring system and serve as the basis for organizing further research, as well as for developing a strategy for environmental management and environmental protection in the Moscow Region.
