Abstract:
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.
