    The dataset comprises data on the substrate type and benthos from 14 samples colected in NW Black Sea in the August 1998. The quantitative (1/133 m2) undisturbed sediment samples were taken with a multicorer Mark II-400, the integral 0-15 cm layer of surface sediment were retained, preserved in 4% formaldehyde. The database comprises taxonomic and quantitative data (density and wet weight biomass per square meter) for 28 macrobenthic species and 2 supraspecific groups.

    The dataset comprises data on the substrate type, temperature, salinity and benthos from 567 samples colected in Romanian Black Sea Shelf, in the period 16.04.1954 - 14.02.1968. The sediment samples were taken with a Van-Veen grab, the sampling size - 0.1 m2. The sediment was preserved in buffered formalin 4% , then sieved through a 2 mm, 0.25 mm and 0.10 mm mesh sieve and subsequently stored in 70% ethanol. The database comprises taxonomic and quantitative data (individuals count, density and biomass per square meter) for 97 macrobenthic species and 5 supraspecific groups.

    The dataset comprises data on the substrate type, temperature, salinity, oxygen saturation, and macrozoobenthos from samples colleceted at several stations in the Black Sea in 2003–2011. The sediment samples were taken with a Van-Veen grab. The sediment was preserved in buffered formalin 4% , then sieved through a 1 mm, 0.5 mm and 0.10 mm mesh sieve and subsequently stored in 70% ethanol. The database comprises taxonomic and quantitative data (density and wet weight biomass per square meter).

    The dataset comprises data on the substrate type, temperature, salinity and benthos from 77 samples colected in 3 fixed points (P1 - 44.2357 Lat. N, 28.6288 Long. E, depth - 1.5 m; P2 - 44.2388 Lat. N, 28.6363 Long. E, depth - 4.5 m; P3 - 44.2416 Lat. N, 28.6447 Long. E, depth - 8 m) in the period 20.10 1959 - 2.11.1961, in Mamaia sector (Constanta, Romanian Black Sea Coast). The sediment samples were taken with a Van-Veen grab, the sampling size of the first 28 samples was - 0.1 m2, while for the rest of 29 - 77 samples it was 0.05 m2.. The samples have been preserved with 10% buffered formalin, then sieved through a 1 and 0.25 mm mesh sieve and subsequently stored in 70% ethanol. The database comprises taxonomic and quantitative data (individuals count, density and wet weight biomass per square meter) for 30 macrobenthic species and 6 supraspecific groups.

    The dataset comprises data on the substrate type, temperature, salinity and benthos from 21 samples colected in NW Black Sea in the period 9-24 May 1997. Benthos samples have been take with a cylindrical plagtic bottle with cut off bottom named "Bucov" (S=1/172 cm2, h=10-12 cm). The sediment was preserved in buffered formalin 4% , then sieved through a 1 and 0.25 mm mesh sieve and subsequently stored in 70% ethanol. The database comprises taxonomic and quantitative data (density and wet weight biomass per square meter) for 75 macrobenthic species and 2 supraspecific groups.

    The dataset comprises data on the substrate type, temperature, salinity and benthos from 58 samples colected in Danube front area in the period March 1960 - July 1960, (Sulina-Portita sector, Romanian Black Sea Coast). The sediment samples were taken with a Van-Veen grab, the sampling size is was - 0.1 m2. The samples have been preserved with 10% buffered formalin, then sieved through a 2 mm, 0.25 mm and 0.10 mm mesh sieve and subsequently stored in 70% ethanol. The database comprises taxonomic and quantitative data (individuals count, density and wet weight biomass per square meter) for 95 macrobenthic species and 10 supraspecific groups.
