Abstract

Benthic species records of deep-sea fauna distributed along the Brazilian Continental Margin (BCM), synthesized from published databases, were mapped in ArcGIS and the here included shapefiles for each phylum were annexed. Two existing biogeographic schemes for the South Atlantic bathyal and abyssal depths (Spalding et al., 2007; Watling et al., 2013) were tested using the distribution data of benthic species along the BCM. A third biogeographic scheme was tested to assess the relationship between benthic fauna and deep water masses within the Brazilian EEZ. Species occurrences were assigned to the biogeographical units of each biogeographical scheme from which the three occurrences databases (watling, hybrid, water masses), included here, were generated. The original data in PANGAEA can be accessed at https://doi.org/10.1594/PANGAEA.950138.
