Information Technologies for Environmental Monitoring of Plankton Algae Distribution Based on Satellite Image Data

Abstract

The paper discusses the features and specifics of using the methods of remote sensing of the Earth when monitoring the ecological and technical state of water management process systems. A technology for monitoring surface waters according to remote sensing of the Earth is proposed. A method of satellite monitoring of algal bloom intensity (monitoring of planktonic algae clusters) has been proposed and substantiated. An approach to flood risk assessment using satellite observations is proposed. The technique of quantitative assessment of water quality according to the space monitoring of surface waters is substantiated. As a result of the research, it was found that when assessing the complex effects of pollutants on the ecological state of aquatic ecosystems using aerospace technologies, it is advisable to take into account changes in biological indicators (indicators of biomass and species composition of phytoplankton and higher aquatic plants). A method has been developed for predicting the long-term risks of emergency situations of a hydrological and hydrometeorological nature based on physical and mathematical modeling and the use of satellite observations and spatially distributed data. According to the results of further studies based on the results obtained in this work, it is planned to create flood risks distribution maps, quantitative predictions of surface water quality deterioration, as well as an assessment of the risks of air and soil pollution.
