The main subject of research is the ecological study of marine ecosystems. Data about the research studies,conducted by a team of SSC RAS and IAZ SSC RAS, assessment of the degree of completeness of the information about the received measurements, and in thefuture the results of these measurements, should be made available to all users in organization. However, often users do not have working with a specialized GIS software or have not special software on each user’s workplace.Additionally, strict requirements impose for the shared storage of the data. Using the «cloud» or geoportal technologies allows the means available to solve this problem. And it should be noted that all requirements for security, access privileges, organization of data transfer is solved on the side of «the cloud».

To create a new version of a web application based on the «cloud»technologies were used MS Access, ArcGIS Desktop, ArcGIS Online. GIS-project,submitted for publication in the “cloud”, includes database and GIS applications of the local version information system “Ecological study of the southern seas of Russia”.
