This dataset contains meiofauna abundance data collected from ROV pushcore samples (PUC) in disturbed areas of the DISCOL experimental area (Peru Basin), collected onboard RV Sonne during expedition SO242/2 in 2015. Meiofauna taxa have been counted and identified at different microhabitats within old disturbance tracks in the area, created by a plough harrow to mimick deep-sea mining impact. Each push core has been subjected to further division in vertical sediment slices (0-1 cm, 1-2 cm and 2-5 cm) and meiofauna has been counted in each separate slice. Meiofauna abundances have been standardized to individuals per 10cm² and are given per taxonomic group (phylum level) and sediment slice. Data has been collected and analysed by the Marine Biology Research Group of Ghent University, Belgium.
