Hydrothermal sulfide accumulation along the Endeavour Segment, Juan de Fuca Ridge

Earth and Planetary Science Letters, 2014
Highlights • High-resolution AUV bathymetry is used to identify hydrothermal sulfides on the seafloor. • 1.2 Mt of massive sulfide is identified along 24 km of mid-ocean ridge length. • Massive sulfide accumulated at a rate of ∼400 t/yr. • Efficiency of sulfide deposition is ∼5% of total mobilized metals and reduced sulfur. • Current global

Growth of large sulfide structures on the endeavour segment of the Juan de Fuca ridge

Earth and Planetary Science Letters, 1986
Abstract Mapping and sampling with DSRV “Alvin” has established that sulfide blocks 0.5 m across, dredged from the axial valley of the Endeavour Segment at 47°57′N, are samples of unusually large sulfide structures. The steep-sided structures, up to 30 m in length, 20 m in height, and 10–15 m across, are localized by venting along normal faults at ...

Estimates of crustal permeability on the endeavour segment of the Juan de Fuca mid-ocean ridge

Earth and Planetary Science Letters, 1996
Observational studies of hydrothermal venting on the Endeavour segment of the Juan de Fuca Ridge place strong constraints on the spacing and area of vent fields, the depth of circulation, and the hydrothermal heat flux. A method is described to estimate a uniform crustal permeability from these parameters under the assumptions that upflow is confined ...

Ascending and descending particle flux from hydrothermal plumes at Endeavour Segment, Juan de Fuca Ridge

Deep-Sea Research Part I: Oceanographic Research Papers, 2001
Abstract Bio-acoustic surveys and associated zooplankton net tows have documented anomalously high concentrations of zooplankton within a 100 m layer above the hydrothermal plumes at Endeavour Segment, Juan de Fuca Ridge. These and other data suggest that congregating epi-plume zooplankton are exploiting a food substrate associated with the ...

Gradients in the composition of hydrothermal fluids from the Endeavour segment vent field: Phase separation and brine loss

Journal of Geophysical Research, 1994
Hydrothermal fluid samples collected in 1984, 1987, and 1988 from a large vent field near 47°57′N on the Endeavour segment of the Juan de Fuca Ridge (JFR) have been analyzed for major and minor elements and gases. There are of the order of 100 individual smoker vents on ∼10 large sulfide structures, which are localized along faults and fault ...
