Abstract
The development of oil and gas fields in the Northern Caspian caused an intensive anthropogenic load and the need to create data warehouses for hydrological, hydrochemical, and biota data for research related to a retrospective assessment of the degree to which anthropogenic impact on a biota affects the biota of different directions. The main goal of the article is the use of algorithmic tools for analytical processing and interpretation of the results of environmental observations in the water area of the Northern part of the Caspian Sea to predict the occurrence and development of environmental changes in the environment, and the organization of centralized storage of heterogeneous (hydrochemical and hydrobiological, etc.) data. The use of the selected software platform (TOFI) to obtain, exchange and process data will allow to provide sections of multi-dimensional cubes of bio monitoring data of the ecosystem of the Northern part of the Caspian Sea to decision-makers and the public.
