| contents | Between September and October 2017, MUC cores were deployed at various locations across the Northeast Greenland (NEG) shelf with R/V Polarstern during PS109. Samples for meiofauna were collected with a cut-off 10 ml syringe (area 1.89 m²) that was inserted to 5 cm depth sediment depth in the MUC core, and subsequently sliced in 5 horizons of 1 cm. Afterwards, meiofauna were extracted from the samples by triple density centrifugation with the colloidal silica polymer LUDOX TM 40 (Heip et al., 1985) and rinsed with freshwater on stacked 1 mm and 32 µm mesh sieves. The fraction retained on the 32 µm mesh sieve was preserved in 4 % Li2CO3-buffered formalin and stained with Rose Bengal. Nematodes of each sample were handpicked with a fine needle, transferred to glycerine (De Grisse I, II and III) (Seinhorst, 1959) , mounted on glass slides, identified to genus level and allocated to functional feeding groups based on Wieser, 1953 (as selective deposit feeders - 1A, non-selective deposit feeders - 1B, epistratum feeders - 2A and predators/scavengers - 2B). |
