Stauromedusan populations inhabiting deep-sea hydrothermal vents along the southern East Pacific Rise
Dense populations of “stalked jellyfish” (Stauromedusae) were encountered at two geographically-separated, deep-sea hydrothermal vent fields located at 7°26’S; and 20°02’S along the East Pacific Rise (EPR). DSV Alvin was utilized (on dives 3320 and 3334) at the sites to collect numerous stauromedusans, which were immediately frozen (at -70°C) or preserved in 70% ethanol upon arrival on board th...
متن کاملInterrelationships between Vent Fluid Chemistry, Temperature, Seismic Activity, and Biological Community Structure at a Mussel-dominated, Deep-sea Hydrothermal Vent along the East Pacific Rise
In April 1991, submarine volcanic eruptions initiated the formation of numerous hydrothermal vents between 9 45# and 9 52#N along the crest of the East Pacific Rise (EPR). Dramatic changes in biological community structure and vent fluid chemistry have been documented throughout this region since the eruptive event. By April 2004, mussels (Bathymodiolus thermophilus) dominated the faunal assemb...
متن کاملComparative phylogeography among hydrothermal vent species along the East Pacific Rise reveals vicariant processes and population expansion in the South.
The use of sequence polymorphism from individual mitochondrial genes to infer past demography has recently proved controversial because of the recurrence of selective sweeps acting over genes and the need for unlinked multilocus data sets. However, comparative analyses using several species for one gene and/or multiple genes for one species can serve as a test for potential selective effects an...
متن کاملEvidence for hydrothermal Archaea within the basaltic flanks of the East Pacific Rise.
Little is known about the fluids or the microbial communities present within potentially vast hydrothermal reservoirs contained in still-hot volcanic ocean crust beneath the flanks of the mid-ocean ridge. During Alvin dives in 2002, organic material attached to basalt was collected at low, near-ambient temperatures from an abyssal hill fault scarp in 0.5 Ma lithosphere on the western ridge flan...
متن کاملManifestations of hydrothermal discharge from young abyssal hills on the fast-spreading East Pacific Rise flank
Spectacular black smokers along the mid-ocean-ridge crest represent a small fraction of total hydrothermal heat loss from ocean lithosphere. Previous models of measured heat flow suggest that 40%–50% of oceanic hydrothermal heat and fluid flux is from young seafloor (0.1–5 Ma) on mid-ocean-ridge flanks. Despite evidence that ridge-flank hydrothermal flux affects crustal properties, ocean chemis...
