Nematode communities from a natural oil seep off Svalbard
Balsa, J.; Argentino, C.; Riva, F.; Adão, H.; Panieri, G.; Ramalho, S.P.Cold-seep sediments, where active fluid seepage rich is observed, have been associated with the presence of endemic nematode communities. Under the scope of the AKMA project, a seep site located offshore Svalbard was sampled for the first time to investigate the Nematoda assemblages associated with methane and crude oil seepage. Replicated samples were collected by means of the blade- and push-cores, on a bacte...
Nematode communities from a natural oil seep off Svalbard.
Balsa, J.; Argentino, C.; Riva, F.; Adão, H.; Panieri, G.; Ramalho, S.P.Cold seeps are considered hotspots of energy on the seafloor, establishing unique conditions for life to thrive. In chemosynthetic-based habitats such as these, sediments from active sites are typically inhabited by endemic nematode communities which tolerate the local reduced environmental conditions, but no studies have been carried out on seep sites so far north in the Arctic. Under the scope of the AKMA pro...
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...
