The project aimed at mapping and assessing the state of benthic habitats, thus contributing to the development of appropriate management measures for the sustainable use of marine resources. Information on benthic habitats on the Romanian continental shelf of the Black Sea and the species inventory were updated, and an estimate of the density and biomass of benthic populations was made. Thus, the project contributed to a better understanding of the dynamics, biotic potential and productivity of each investigated habitat type. The results were included in the database for integrated environmental monitoring at national and international scale.
