Schnier, Jannik; Grzelak, Katarzyna; Hasemann, Christiane; Soltwedel, Thomas: Data on nematode genus abundance and counts at LTER HAUSGARTEN from 2000 to 2009, 2010, 2014 and 2019 [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.973147 (dataset in review)
Abstract:
This dataset contains information on Arctic deep-sea nematode abundance calculated for 10 cm² of seafloor on genus level (time period 2000 to 2009), as well as counts (years 2010, 2014 and 2019). Sampling was carried out in the Arctic summer with a multiple corer (MUC) at the LTER HAUSGARTEN observatory at three stations in 2000 to 2009, 2014 and 2019 (HG-I, HG-IV, HG-VII), and at nine stations in 2010 (HG-I to HG-IX). 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.
