This dataset contains abundance (i.e., absolute number of speicmens/individuals) of ostracod genera collected during three cruises of the German Research Vessel Polarstern in the Atlantic Sector of the Southern Ocean. The cruises are EASIZ II (PS 48/ANT XV-3), ANDEEP I (PS 61/ANT XIX-3), ANDEEP II (PS 67/ANTXXII-3), and ANDEEP III (PS 67/ANTXXII-4). The samples related to the present file were all collected using an epibenthic sledge, described by (Brandt & Barthel, 1995; Brenke, 2005, see compelte references in Brandão et al., 2021, Zoological Journal of the Linnean Society). These ostracods are both benthic (most specimens collected) and bentho-pelagic (Halocyprididae, which in the case of the present dataset, swam just above the sea floor). ... : From the Material and Methods session of the paper, which analysed this dataset (Brandão et al., 2021): "The 51 samples studied herein (Fig. 1, Tab. 1) were collected in the Atlantic sector of the SO during four cruises of the projects ANDEEP (I, II and III cruises) and EASIZ (Ecology of the Antarctic Sea Ice Zone) (II cruise) (for details see Brandt et al., 2007b; Arntz & Gutt, 1999). The ANDEEP (Antarctic benthic DEEP-sea biodiversity: colonization history and recent community patterns) project provided samples from the deep continental shelf (753 m) to the abyss (6340 m). While during the EASIZ project samples were recovered from the relatively shallow continental shelf (189 m) to the deep slope (2076 m). The gear used in the sampling was an EpiBenthic Sledge (EBS), which holds two sampling boxes (opening of 100 cm width and 33 cm height), with one sampler plankton net attached (0.5 mm mesh size for the epinet and supranet, and 0.3 mm for the cod ends) (for a detailed description of the gear, see ...
