Vulnerable marine ecosystems survey pilot missions with EVA Hybrid AUV/ROV
Almeida, Carlos; Martins, Alfredo; Soares, Eduardo; Santos, A. Miguel P.; Matias, Bruno; Silva, Pedro; Pereira, Ricardo; Sytnyk, DenysFishing for deep-sea species occurs on continental slopes, ridges, and seamounts. Fishing operations using fishing gears that contact the bottom (e.g., trawls and bottom longlines) may have significant impacts on Vulnerable Marine Ecosystems (VMEs). VMEs refer to marine ecosystems with a population or community of sensitive taxa or habitats that are likely to experience substantial alteration from short-term to...
A decade to study deep-sea life
Howell, Kerry L.; Hilario, Ana; Allcock, A. Louise; Bailey, David; Baker, Maria; Clark, Malcolm R.; Colaco, Ana; Copley, Jon; Cordes, Erik E.The United Nations Decade of Ocean Science for Sustainable Development presents an exceptional opportunity to effect positive change in ocean use. We outline what is required of the deep-sea research community to achieve these ambitious objectives.
A blueprint for an inclusive, global deep-sea ocean decade field program
Howell, Kerry L.; Hilário, Ana; Allcock, A. Louise; Bailey, David M.; Baker, Maria; Clark, Malcolm R.; Colaço, Ana; Copley, Jon; Cordes, Erik E.The ocean plays a crucial role in the functioning of the Earth System and in the provision of vital goods and services. The United Nations (UN) declared 2021-2030 as the UN Decade of Ocean Science for Sustainable Development. The Roadmap for the Ocean Decade aims to achieve six critical societal outcomes (SOs) by 2030, through the pursuit of four objectives (Os). It specifically recognizes the scarcity of biolo...
Benthic nematode biodiversity of the Abzu, Tiamat and Michael Ivanov mud volcan...
Ramalho, Sofia P.; Ribeiro, Carlos; Hensen, Christian; Scholz, Florian; Nuzzo, Marianne; Terrinha, Pedro; Adão, HelenaStudies that focus on meiofaunal assemblages of deep-sea mud volcanoes show an unpredictable abundance and diversity in a clear response to the different environmental conditions of the seeped sediment. The mud volcanoes Abzu, Tiamat and M. Ivanov (ATI), are located along the SWIM1 fracture zone, in front of the accretionary wedge of the Gulf of Cadiz (AWGC). The geological setting and the fluid geochemical cha...
Bottom-trawling fisheries influence on standing stocks, composition, diversity ...
Ramalho, Sofia P.; Almeida, Mariana; Esquete, Patricia; Génio, Luciana; Ravara, Ascensão; Rodrigues, Clara F.; Lampadariou, Nikolaos; Vanreusel, AnnBottom-trawling fisheries operating in Portugal (West Iberian Margin) impose one of the largest footprints per unit of biomass landed in European waters at depths greater than 200 m, affecting the seafloor integrity and the associated benthic fauna. To investigate how trawling pressure is affecting the macrofaunal assemblages, we compared the standing stock (abundance and biomass), community structure and taxon...
