In this work, we integrate five case studies harboring vulnerable deep-sea benthic habitats in different geological settings from mid latitude NE Atlantic Ocean (24–42° N). Data and images of specific deep-sea habitats were acquired with Remoted Operated Vehicle (ROV) sensors (temperature, salinity, potential density, O2, CO2, and CH4). Besides documenting some key vulnerable deep-sea habitats, this study shows that the distribution of some deep-sea coral aggregations (including scleractinians, gorgonians, and antipatharians), deep-sea sponge aggregations and other deep-sea habitats are influenced by water masses’ properties. Our data support that the distribution of scleractinian reefs and aggregations of other deep-sea corals, from subtropical to north Atlantic could be dependent of the latitudinal extents of the Antarctic Intermediate Waters (AAIW) and the Mediterranean Outflow Waters (MOW). Otherwise, the distribution of some vulnerable deep-sea habitats is influenced, at the local scale, by active hydrocarbon seeps (Gulf of Cádiz) and hydrothermal vents (El Hierro, Canary Island). The co-occurrence of deep-sea corals and chemosynthesis-based communities has been identified in methane seeps of the Gulf of Cádiz. Extensive beds of living deep-sea mussels (Bathymodiolus mauritanicus) and other chemosymbiotic bivalves occur closely to deep-sea coral aggregations (e.g., gorgonians, black corals) that colonize methane-derived authigenic carbonates.

The Many

The oceans make up about 70% of the earth’s surface and serve as habitats for many deep and shallow creatures. In depths of about 50 meters and more, deep-sea corals and sponges occur mostly along seamounts, continental margins, undersea canyons and ridges. They, deep-sea corals and sponges, play a key role in supporting the health of the ocean as they preserve the biodiversity and long-term sustainability of commercial and recreational fish species. With the many benefits that are attached to deep-sea corals and sponges, the Deep-Sea Corals and Research Technology Program (DSCRTP) has been collecting coral and sponge location data from hundreds of remotely operated vehicle (ROV) surveys. However, DSCRTP does not have a spatial representation of the area covered by each ROV while searching for corals and sponges in the deep-sea. A spatial representation would provide critical information to researchers and managers to understand where a survey for corals and sponges has happened, and where a survey is yet to be done in the deep-sea. Therefore, the goal of this study is to create a spatial representation of the ROV surveys that have been collected in Monterey Bay and Hawaii sections of the deep-sea.
