The study area covers three submarine canyons and a rocky outcrop, and was sampled using non-invasive photogrammetric techniques. To study the community structure, we analyzed the aggregations of sessile macrobenthic species using hierarchical cluster analysis based on Bray-Curtis similarity index. The main groups obtained were cold-water corals accompanied by hexactinellid sponges, brisingids and black corals; aggregations of demosponges; a sedimentary habitat dominated by pennatulids; and two lower bathyal habitats, one dominated by Acanthogorgia armata and Thouarella (Euthouarella) grasshoffi, and another by the foraminifera Syringammina aff. fragilissima. To obtain their spatial distribution, we developed two-part hurdle models for each group by combining binomial presence–absence predictions with negative binomial density models of key species, identified by a similarity percentage analysis. Results indicated high densities of cold-water corals along the canyon walls and in deep biogenic and geogenic zones; sponge aggregations on shallow hard substrates, and high density of pennatulids, mainly Kophobelemnon stelliferum, in sedimentary areas. These findings provide an essential baseline knowledge for the implementation of on ecosystem-based management plans and conservation strategies.This study was made possible thanks to the invaluable work of all the participants in the five surveys involved and the crews of the R/Vs Ramón Margalef and Angeles Alvariño. The authors also appreciate the helpful assistance of the technicians of the ROTV Politolana and ROV Liropus 2000 for their skill in executing the visual transects very close to the rough bottoms of the study area. This research has been performed in the scope of the INTEMARES project. INTEMARES was partially funded by the European Commission LIFE C “Nature and Biodiversity” call (LIFE15 IPE ES 012). The Biodiversity Foundation, of the Ministry of Environment, was the institution responsible for coordination this project.Peer reviewedElsevierEuropean CommissionMinisterio para la Transición Ecológica y el Reto Demográfico (España)Rodríguez-Basalo, Augusto [0000-0002-4626-3194]Gómez-Ballesteros, María [0000-0002-0772-9211]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202620262026info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://hdl.handle.net/10261/419075https://api.elsevier.com/content/abstract/scopus_id/105028258091reponame:DIGITAL.CSIC.
