The Black Sea is one of the most isolated inland seas in the world. The Black Sea biodiversity is rather confined in comparison, for instance, with the Mediterranean Sea, owing to its geographical isolation, low water salinity and cooler environment, as well as because of a large amount of anoxic waters enriched with poisonous hydrogen sulphide. The Black Sea represents a specific bio-geographic region with its own characteristic blend of vegetation, climate and geology.

The Black Sea plays enormous social and economic role for the surrounding countries it provides important food (fish, molluscs), transport links to the other seas, recreational values. The marine ecosystem is highly fragile due to its isolation and many species are in bad conservation status. Different pressures and threats affect the Black Sea negatively: over fishing, pollution and introduction of invasive alien species, climate change, etc.

General public is getting more and more sensitive to the environmental problems and is urging governments to act. In recent years at global scale new concept for development of different spheres of science is applied citizen science or "public participation in scientific research". This approach is scientific research conducted, in whole or in part, by amateur or nonprofessional scientists mainly in collection of data on observations or regular monitoring of target species. Main stakeholder groups will be people living in the coastal areas as well as holiday-makers, students in natural sciences and groups that regularly sail the seas (yachtsmen, sailors, fishermen).

The actions main goal is raising public awareness on the Black Sea biodiversity and the contribution each one can made for conservation of this fragile ecosystem. Using a contemporary tool like smart phone application and web-based data base will guarantee the interest of the young increasingly using these tools rather than older means of communication and data recording.

Smart phone Apps and website should include information for identification of all marine species (mammals, birds, fish, invertebrates, macroalgae, etc.) in the Black Sea, especially species in the Red Data Book, invasive, harmful and key species. Users will be able to send photographs with location data (GPS) through this system. After the confirmation of the identification of the species by experts, the record will be added to the map on the project website. In this way everyone can see the distribution map of marine creatures in the Black Sea and become a part of a scientific project. The gathered information is aimed to be published in scientific journals with the cooperation of both amateur and professional scientists. The obtained data will be used with the permissions of data contributors. Essentially, this is a project adapted to our region (Black Sea), called "Citizen Science" in European countries, which aims to collect data for social benefits by an easy and inexpensive way and also increasing public awareness on marine biodiversity.
