Abstract

Blooming of inland water bodies is caused by the intensive development of phytoplankton cells in the surface layer of water bodies, as a rule, in summer. Therefore, the development of methods for controlling this process is relevant. One of the methods for assessing the flowering intensity is based on determining the concentration of chlorophyll a, which allows obtaining objective information about the intensity of photosynthesis and phytoplankton biomass and the quality characteristics of the surface water layer. In this work, an assessment is made of the spatial content of chlorophyll a in the surface layer of water bodies: the Novosibirsk reservoir, lakes Krasilovskoe and Itkul (Altai Territory) in 2017, 2018 according to the data of the spacecraft Sentinel-2 and the results of local sampling and analysis of water. Data processing processes and presentation of calculation results are implemented in the form of a geoinformation web-system. This allows you to automate the computing processes and organize access to data.
