The main aim of the dataset is preparing the available data by diversity and distribution of the Black Sea seagrasses, which were collected the scientists from IBSS around Ukranian and Russian coastal zone during last 50 years (1960 - 2009). The data about region, location, sampling equipment are given for each seagrass species. The species diversity is described from 45 transects, 164 stations at 0,3 - 20 m depth. These data are available now for scientists, professionals and they can be used in various purposes.

The hypothesis that, temporal variation in nematode abundance, community composition and trophic structure is coupled with changes in the quantity and quality of their potential food sources was tested.

Data on <i>Posidonia oceanica</i> collected during spring and summer 2005 in three sites within the Bay of Roses.

Counts of observed fish species and numerical and gravimetrical stomach analysis for 9 fish species at the West and East creek of Gazi Bay during a 2 day sampling in August 1993. The data were digitized by VLIZ from the original report: De Troch, M. (1995).
