Abstract. The flexible integration of diverse data on aquatic organisms and their habitats is the first step towards developing a valuable tool for comprehensive biodiversity analysis. The Black Sea provides a relevant example for creating such a tool. We analyzed the possibilities of obtaining and integrating data from various systems, such as WoRMS, GenBank, GBIF, and OBIS. Using approaches similar to those used in the design of distributed systems, we carried out the primary specification of methods and tools for analyzing biological diversity in the Black Sea and Azov regions. Implementation of these methods enables combining different datasets, determining taxon presence, searching for genetic data, and analyzing taxon distribution in time and space. This approach ensures standardization and consolidation of data from multiple sources, as well as storage in structures providing easy and fast access.
