Here we provide a summary of the topography and oceanography of the North Atlantic including the Gulf of Mexico and Caribbean Sea, provide a brief overview of the history of scientific research therein, and review the current status of knowledge of each of 18 pelagic and benthic deep-sea ecosystems, with a particular focus on knowledge gaps. We analyse biodiversity data records across the North Atlantic and highlight spatial data gaps that could provide important foci for future expeditions. We note particular data gaps in EEZs of nations within and bordering the Caribbean Sea. Our data provide a baseline against which progress can be tracked into the future. We review human impacts caused by fishing, shipping, mineral extraction, introduction of substances, and climate change, and provide an overview of international, regional and national measures to protect ecosystems. We recommend that scientific research in the deep sea should focus on increasing knowledge of the distribution and the connectivity of key species and habitats, and increasing our understanding of the processes leading to the delivery of ecosystem services. These three pillars - distribution, connectivity, ecosystem function - will provide the knowledge required to implement conservation and management measures to ensure that any deep-sea development in the future is sustainable. Infrastructure and capacity are unevenly distributed and implementation of strategies that will lead to more equitable deep-sea science is required to ensure that essential science can be delivered.
- A pioneering longterm experiment on mesophotic macrofouling communities in the North AtlanticPublication . Canning-Clode, João; Gizzi, Francesca; Braga-Henriques, Andreia; Ramalhosa, Patrício; Abreu, Pedro; Álvarez, Soledad; Biscoito, Manuel; Buhl-Mortensen, Pål; Delgado, João; Esson, Diane; Freitas, Mafalda; Freitas, Magno; Henriques, Filipe; Jakobsen, Joachim; Jakobsen, Kirsten; Kerckhof, Francis; Lüter, Carsten; Moura, Carlos J.; Radeta, Marko; Rocha, Rosana M.; Santos, Romana; Sepúlveda, Pedro; Silva, Rodrigo; Silva, Teresa; Souto, Javier; Triay-Portella, Raül; Wirtz, Peter; Xavier, Joana R.; Bastida-Zavala, Rolando; Bellou, Nikoleta; Gueroun, Sonia K. M.; Monteiro, João G.The mesophotic zone represents one of our planet's largest and least explored biomes. An increasing number of studies evidence the importance of macrofouling species in marine ecosystems, but information on these communities and the factors influencing their structures at mesophotic depths remain poor. This lack of understanding limits our ability to predict anthropogenic impacts or conduct restoration operations in the mesophotic and the lower boundary of the euphotic zones. In this study, we performed a 24-month experiment in a natural environment to investigate three factors influencing the macrobenthic community structure of the mesophotic and the euphotic lower boundary: depth, substrate orientation and substrate material. Using a manned submersible, several recruitment panels of two different materials were deployed at 100, 200 and 400 meters in vertical and horizontal positions. All three factors contributed to structuring the macrofouling communities, but depth and substrate orientation displayed the strongest effects. This study not only advances our understanding of lower boundary euphotic and mesophotic macrofouling communities but also establishes a foundation for future research and restoration efforts of mesophotic environments in the Madeira archipelago, where mesophotic habitats are amongst the least studied marine habitats in the Northeast Atlantic.
