| Summary: | Planktonic foraminifera preserved in marine sediments archive the physical and chemical conditions under which they built their shells. To interpret the paleoceanographic information contained in fossil foraminifera, the proxy signals have to be attributed to the habitat of individual species. Much of our knowledge on habitat depth is based on indirect methods, which reconstruct the depth at which the largest portion of the shell has been calcified. However, habitat depth can be best studied by direct observations in stratified plankton nets. Here we present a synthesis of living planktonic foraminifera abundance data in vertically resolved plankton net hauls taken in the eastern North Atlantic during twelve oceanographic campaigns between 1995 and 2012. Live (cytoplasm-bearing) specimens were counted for each depth interval and the vertical habitat at each station was expressed as average living depth (ALD). This allows us to differentiate species showing an ALD consistently above 100 m (e.g. ... : Supplement to: Rebotim, Andreia; Voelker, Antje H L; Jonkers, Lukas; Waniek, Joanna J; Meggers, Helge; Schiebel, Ralf; Fraile, I; Schulz, Michael; Kucera, Michal (2017): Factors controlling the depth habitat of planktonic foraminifera in the subtropical eastern North Atlantic.
