Abstract Continuous time-series observations are key to understanding the temporal evolution of a seafloor hydrothermal system and its interplay with thermal and chemical processes in the ocean and Earth interior. In this paper, we present a 26-month time series of the heat flux driving a hydrothermal plume on the Endeavour Segment of the Juan de ...

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 ...

228Th/228Ra ages of a barite-rich chimney from the Endeavour Segment of the Juan de Fuca Ridge
Earth and Planetary Science Letters, 1995Ages in the range 1–15 yr for chimneys deposited from hydrothermal vents from the Endeavour Segment of the Juan de Fuca Ridge are estimated based on the ingrowth of228Th from228Ra. Cleaning samples by digestion in an acid bath confirms that the mineral barite is the phase being dated. A detailed examination of sample ALV 2463 R7 collected from the Clam

Major and trace element data for a suite of lavas from fifty‐six dredges and ALVEN dives on the ridge axis and adjacent abyssal hills have been used to investigate the geometry and evolution of magmatic systems beneath the Endeavour Segment, Juan de Fuca Ridge.

Geological Society of America Bulletin, 1986
A 36-km-wide corridor of Seabeam bathymetry was collected on the Juan de Fuca Ridge, north of 48°00′N, in May 1983. These data, merged with previous Seabeam bathymetric compilations for the Cobb Offset, as well as with Sea MARC I and Sea MARC II side-scan sonar, seismic-reflection, magnetometer, and deep-tow photography data, have been used to identify

The complex bathymetry and buoyancy fluxes associated with active spreading centres have a strong influence on the circulation and water properties in the region. The mixing of hot fluid (∼ 350 °C) emitted from hydrothermal vents with the surrounding sea water (∼ 2 °C) exerts control over circulation and transport of larvae, nutrients, microbes and ...

Inactive seafloor hydrothermal vents on the seafloor are continuously exposed to oxygen-rich seawater and subjected to oxidative processes. These processes result in mineral breakdown, structural instability, and eventual collapse of the vents.

The Endeavour Ridge is a segment of the Juan de Fuca Ridge, an active spreading centre which lies off western North America between the Pacific and Juan de Fuca plates. This segment is a bathymetric high and a site of hydrothermal activity—both characteristics suggest an underlying heat source such as an axial magma chamber which is associated with ...
