Currently it is necessary to form complex scientific approaches to the assessment of the dynamics of quantitative and qualitative indicators hydro, chemical and biological state of the Caspian Sea ecosystem. Assessment of the sea state is based on the target field and experimental studies of research institutes, as well as data obtained from State Observation Network (SON) as a part of monitoring system of the marine environment and results based on the monitoring of large offshore oil and gas projects. The main goal of research is ecological and geographical mapping of the Northern Caspian. The results will help to establish general patterns of long-term spatial and temporal distribution of indicators of hydro chemical and biological parameters, as well as the level of pollution of the marine environment. Determination of sustainable properties of the waters can be used in the economic and environmental activities on the northern shelf of the Caspian Sea and to create an optimized environmental monitoring system. Also, it is neccessary to use ecological and geographical approach, which determines the territory of the North Caspian Sea as a specific uniform hydrodynamic system, strongly linked with surrounding land, their hydro climatic, ecological and economic characteristics. Ecological and geographical mapping of the Northern Caspian Sea was based on aggregate analysis of the physical and chemical properties of the water masses and major pollutant indicators using geo-information technologies. As a result of research spatial database of different properties of water of North Caspian Sea was created. Database allows querying over a large number of environmental parameters, building their statistical and graphical evaluation on the basis of long-term data set (1978-2014). Results of database analysis can be visualized in ArcGIS software.
