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 m, separated in two layers depending on the physical-biological scenario, 100–200, 200–300, 300–400, 400–500, 500–600, and 600–800 m depth layers). 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.-31.8851-17.4206-10.081325.3464Central AtlanticHorizon 2020https://doi.org/10.13039/501100007601817578Tropical and South Atlantic climate-based marine ecosystem predictions for sustainable managementHorizon 2020https://doi.org/10.13039/501100007601817806Sustainable management of mesopelagic resourcesSpanish Ministry of Science, Innovation and Universitieshttps://doi.org/10.13039/501100004837CTM2012-39587-C04Migrants and Active Flux In the Atlantic OceanSpanish Ministry of Science, Innovation and Universitieshttps://doi.org/10.13039/501100004837PID2020-118118RB-100DisEntangling Seasonality of Active Carbon Flux In The Ocean (DESAFIO)
