Abstract:
This dataset contains information on Arctic deep-sea nematode genus body size, biomass, feeding types, tail shapes and cp-values (years 2010, 2014 and 2019). Sampling was carried out in the Arctic summer with a multiple corer (MUC) at the LTER HAUSGARTEN observatory at nine stations in 2010 (HG-I to HG-IX) and at three stations in 2014 and 2019 (HG-I, HG-IV, HG-VII). From each MUC deployment, three replicate samples were taken from different MUC cores (10 cm diameter), and the top five centimetres of sediment from each replicate sample were subsampled with a syringe (2.2 cm diameter). All samples were fixed in formol (4 %) and rinsed over a 32 µm sieve. The metazoan meiofauna was extracted by centrifugation in colloidal silica. Morphological genus determination, body size measurements and image acquisition of the nematodes were performed under a light microscope equipped with a digital camera and associated software.
