Abstract
In this work, we integrate five case studies harboring vulnerable deep-sea benthic habitatsin different geological settings from mid latitude NE Atlantic Ocean (24–42◦ N). Data and images ofspecific 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-seahabitats, this study shows that the distribution of some deep-sea coral aggregations (including scler-actinians, gorgonians, and antipatharians), deep-sea sponge aggregations and other deep-sea habitatsare influenced by water masses’ properties. Our data support that the distribution of scleractinianreefs and aggregations of other deep-sea corals, from subtropical to north Atlantic could be dependentof the latitudinal extents of the Antarctic Intermediate Waters (AAIW) and the Mediterranean Out-flow 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 hasbeen 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 coralaggregations (e.g., gorgonians, black corals) that colonize methane-derived authigenic carbonates.
