Data collected within the EMBLAS-Plus “EU-UNDP Project 'Improving Environmental Monitoring in the Black Sea' (EMBLAS-Plus)” (http://emblasproject.org/). Mesozooplankton samples were collected by vertical Juday closing net (diameter of 36 cm - 0.1 m2 mouth opening area, and mesh aperture of 150µm) from 3 - 4 meters above the bottom for the shelf waters or from the oxygen minimum zone (Sig T 16.0) for the open sea waters, to the surface, at discrete layers depending of water stratification and thermocline depth. Usually samples from upper mixed layer, thermocline layer and from the oxygen minimum zone up to the thermocline were collected. Mesozooplankton samples were taken at all stations (20 stations - 23 samples). The samples were preserved in buffered with disodiumtetraborate (borax) (Na2B4O3.10H2O) 4% formalin solution. The samples were collected according to SOP for the cruise developed in EMBLAS II.
