Seabed heterogeneity regulates megabenthic community patterns in abyssal nodule fields [Dataset]

Contents Text S1: Methods for sediment sampling and processing. Table S1: Mean total organic carbon (%) (95% intervals) for mining impact areas (MIN) and the preservation reference zone (PRZ) and with samples split by nodule-habitat type (PRZ samples only). Table S2: Mean depth (m), latitude, longitude (decimal degrees) and area (m2, no overlap) for each transect (study area summary in bold). Figure S1: Rarefaction curves for each study area in NORI-D. Figure S2: Ordination of megafaunal communities living in Type 1 nodule-habitat areas across NORI-D. Figure S3: Top contributors to differences between megafauna communities found on different nodule-habitat types based on the results of the SIMPER analysis. Figure S4: Top contributors to differences between megafauna communities found in different study areas based on the results of the SIMPER analysis. Table S3: Morphospecies list including catalogue ID, taxonomic ID and total abundance for each nodule-habitat type and study area. Table S4: Results of the pairwise PERMANOVA testing difference between a) study area; b) type 1 nodule areas in each study area, c) nodule-habitat types within the PRZ
