Occurrence of marine litter along abyssal areas of the Gloria Fracture Zone (NE...
Ramalho, S.; Ferreira, T.; Hensen, C.; Terrinha, P.; Schmidt, M.; Sroczynska, K.; Adão, H.Marine litter pollution is a recognized form of anthropogenic disturbance that affects widely the marine environment, particularly near the continental margins, although also present at abyssal and bathyal depths. This study reports the occurrence of marine litter distribution and abundance in four abyssal basins along the Gloria fracture zone in the NE Atlantic. Litter items occurrences were analysed using TV-...
Megafauna communities from abyssal sites along the Gloria Fracture Zone (NE Atl...
Ferreira, T.; Hensen, C.; Terrinha, P.; Schmidt, M.; Muller, T.; Sroczynska, K.; Ramalho, S.; Adão, H.Fracture zones are areas of poorly known abyssal landscapes and benthic faunal communities. During the R/V Meteor M162 cruise several imagery surveys were performed using a TV-CTD guided camera system along four main areas of the Gloria fault system, between the Terceira ridge and the Madeira Tore Rise. Based on these records, we were able to characterize - for the first time - the megafaunal composition, their...
Benthic nematodes assemblages of three new mud volcanoes along the SWIM deep-re...
Ramalho, S.P.; Ribeiro, C.; Hensen, C.; Nuzzo, M.; Terrinha, P.; Adão, H.During the RV METEOR M86/5 cruise (as part of the SWIMGLO project PTDC/MAR/100522/2008) three new mud volcanoes were discovered and characterized at ca. 4500m depths: Michael Ivanov, Abzu and Tiamat, located along the already described lithospheric SWIM1 fault in the transition between the accretionary prism and the Horseshoe Abyssal Plain (Gulf od Cadiz). The benthic nematode assemblages present in the sedimen...
Biological assemblages of three new mud volcanoes along deep-reaching transform...
Cunha, M.; Hilário, Ana; Vieira, R.P.; Adão, H.; Aranda, Silva A.; Ravara, A.; Terrinha, P.; Hensen, C.Previous work on the Gulf of Cadiz (S Iberian Margin) has revealed several mud volcanoes sitting on the accretionary wedge and aligned along west-east trending transform faults. The source of fluids in these mud volcanoes is several kilometres below the seafloor and their geochemical composition indicates that they are affected, in different degrees, by oceanic crust alteration, implying that there is active fl...
