Mesozooplancton abundance from surface to bathypelagic zone in during spring in the Northeast Atlantic Ocean in 2018 (Bathypelagic)

This dataset contains values mesozooplankton abundance groups collected during the Bathypelagic cruise from 24th of May to the 23rd of June 2018, from Northwest Africa (20° N, 20° W) to the South of Iceland. Mesozooplankton were sampled using the Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS-1 m²) zooplankton net with a 0.2 mm mesh size and with several nets for collecting samples from 8 different depth layers (0-100; 100-200; 200-400; 400-700; 700-1000; 1000-1300; 1300-1600; 1600-1900). Collected specimens MOCNESS-1 samples were preserved in 5% buffered formalin, and specimens were sorted out later. All individuals were counted with the exception of Protozoa due to the mesh size used was not suitable to retrieve a representative sample (Boltovskoy, 1981). Most abundant mesozooplankton groups were studied and identified until dominant groups. All data were standardized to number of individuals (#/m³) by layer.
