On land, individual nodules were frozen at -20°C for 24 h to disintegrate the nodules and to release all crevice fauna. Nematode and Copepoda were extracted from the disintegrated nodule by sieving (32 µm mesh size) and centrifugation in a mixture of kaolin mud and levasil. Nematoda and Copepoda in the supernatant were extracted, mounted on microscopy slides and the body size (length, width; in µm) was measured. Dry mass of Nematoda and Copepoda (in µg) was calculated following conversion factors by Warwick & Gee (1984).-117.0602-117.011211.845311.8651Clarion-Clipperton Fraction Zone, North East Pacific OceanDutch Research Councilhttps://doi.org/10.13039/5011000032461745.23.1JPI Oceans project Mining ImpactDutch Research Councilhttps://doi.org/10.13039/501100003246856.18.001JPIO-MiningImpact: JPI Oceans - Ecological Aspects of Deep-Sea Mining (NWO-ALW grant)Dutch Research Councilhttps://doi.org/10.13039/501100003246856.18.003Deep Sea Mining: Fate & toxicity of the sediment plume 2Dutch Research Councilhttps://doi.org/10.13039/501100003246BR/15/MA/JPI-DEEPSEA2JPI Oceans project Mining ImpactDutch Research Councilhttps://doi.org/10.13039/501100003246OCENW.XS24.2.193Deep-sea sponges as sinks of dissolved inorganic carbonDutch Research Councilhttps://doi.org/10.13039/501100003246VI.Veni.212.211Metabolic activity of individual benthic fauna in deep-sea habitats (INBREATH)European Marine Biological Resource Centrehttps://doi.org/10.13039/501100015737I001621NEMBRC Belgium - FWO international research infrastructureEuropean Research Councilhttps://doi.org/10.13039/501100000781101221692Nitrogen cycling in modern sponges with clues about their role in past oceans
