This dataset presents the macrobenthic species abundance and biomass in soft bottom areas located at southeastern Bay of Biscay. Data on organic matter content and grain-size distribution in surficial seafloor sediments is also provided. Samples were obtained with Shipek and Smith-McIntyre type grabs in several surveys carried out between 2010 and 2020, covering a range of depths of 32-2241 m. Abundance and biomass of macrobenthic species are given. This database is useful for (i) research on spatial variability of macrobenthic communities, and (ii) baseline knowledge of species in the area. The research article on these data [1] was published in the journal Regional Studies in Marine Science. Title: Macrofaunal variability in the continental shelf and canyons in the southeastern Bay of Biscay.
