During the Meteor cruise M140 held in Summer 2017, we collected plankton net samples from the surface ocean to 700 m depth along 9 stations in the subtropical eastern north Atlantic Ocean. Planktonic foraminifera were picked out of these samples, identified taxonomically, counted (separating cytoplasm bearing and empty shells) and imaged by a Keyence microscope to obtain individual shell size parameters. Here we provide results (raw counts, concentrations in ind/m3, size parameters such as minor and major axis in µm) for the species Globigerinita glutinata, Globigerinoides ruber ruber, Globorotalia menardii, Orbulina universa and Globigerinella siphonifera (size parameters only) at each station and for each depth. This material was used in the Biogeosciences publication of Meilland et al., 2021, entitled Population dynamics and reproduction strategies of planktonic foraminifera to investigate potential ontogenic vertical migration of planktonic foraminifera in the open Ocean.
