Description
This dataset is the outcome of research done on the benthic system of the Black Sea Shelf. Data on macrobenthos (density and biomass), oxygen flux to the sediment and sediment characteristics are presented. more

This dataset is the outcome of research done on the benthic system of the Black Sea Shelf. From 5 to 27 August 1995, 33 stations were sampled on the northwest continental shelf. Sediment was sampled with a Reineck boxcorer (60 x 30 x 30 cm). In order to detect spatial variations in their distribution, both the biotic (macrofauna) and abiotic (grain size, porosity, ..) component of the sediment was studied. The oxygen flux to the sediment has been measured as an estimation of the rate of benthic mineralization, and the contribution of macrobenthos in total sediment respiration has been calculated. The present dataset contains data on macrobenthic biomass and density and several sediment characteristics. Also, environmental characteristics of the sampling locations can be found.
