Sediment cores were sliced at a depth resolution of 1 cm down to 5 cm depth and the layers were fixed in 4% buffered formalin. Sediment samples were sieved and rinsed on a 20 µm mesh size for meiofauna analyses. Organisms were counted using a stereomicroscope and measured using a light microscope.-71.6207-70.83805000000001-24.285-20.3262Danish National Research Foundationhttps://doi.org/10.13039/501100001732DNRF145Danish Center for Hadal Research, HADAL
