Hydrothermal Chimney Distribution on the Endeavour Segment, Juan de Fuca Ridge [PDF]
Geochemistry, Geophysics, Geosystems, 2020 The Endeavour Segment of the Juan de Fuca Ridge is well known for its abundance of hydrothermal vents and chimneys. One‐meter scale multibeam mapping data collected by an autonomous undersea vehicle revealed 572 chimneys along the central 14 km of the ...

Sulfide geochronology along the Endeavour Segment of the Juan de Fuca Ridge [PDF]
Geochemistry, Geophysics, Geosystems, 2013 Forty‐nine hydrothermal sulfide‐sulfate rock samples from the Endeavour Segment of the Juan de Fuca Ridge, northeastern Pacific Ocean, were dated by measuring the decay of 226Ra (half‐life of 1600 years) in hydrothermal barite to provide a history of hydrothermal venting at the site over the past 6000 years.

Near‐axis crustal structure and thickness of the Endeavour Segment, Juan de Fuca Ridge [PDF]
Geophysical Research Letters, 2016 A model of crustal thickness and lower crustal velocities is obtained for crustal ages of 0.1–1.2 Ma on the Endeavour Segment of the Juan de Fuca Ridge by inverting travel times of crustal paths and non‐ridge‐crossing wide‐angle Moho reflections obtained

Endeavour Segment of the Juan de Fuca Ridge: One of the Most Remarkable Places on Earth [PDF]
Oceanography, 2012 Endeavour Segment of the Juan de Fuca Ridge is one of three Integrated Study Sites for the Ridge 2000 Program. It is a remarkable, dynamic environment hosting five major hydrothermal fields, numerous smaller fields, and myriad diffuse-flow sites; magma ...

A seismic swarm and regional hydrothermal and hydrologic perturbations: The northern Endeavour segment, February 2005 [PDF]
Geochemistry, Geophysics, Geosystems, 2010 The February 2005 swarm at the overlapping spreading center (OSC) on the northern end of the Endeavour segment is the first swarm on the Juan de Fuca Ridge recorded on a local seafloor seismic network. The swarm included several larger earthquakes and caused triggered seismicity and a hydrothermal response in the Endeavour vent fields as well as ...

Seismic structure of the Endeavour Segment, Juan de Fuca Ridge: Correlations with seismicity and hydrothermal activity [PDF]
Journal of Geophysical Research, 2007 Multichannel seismic reflection data collected in July 2002 at the Endeavour Segment, Juan de Fuca Ridge, show a midcrustal reflector underlying all of the known high‐temperature hydrothermal vent fields in this area. On the basis of the character and geometry of this reflection, its similarity to events at other spreading centers, and its polarity, we

Surficial permeability of the axial valley seafloor: Endeavour Segment, Juan de Fuca Ridge
Geochemistry, Geophysics, Geosystems, 2013 Hydrothermal systems at mid‐ocean spreading centers play a fundamental role in Earth's geothermal budget. One underexamined facet of marine hydrothermal systems is the role that permeability of the uppermost seafloor veneer plays in the distribution of hydrothermal fluid.

Geochemistry, Geophysics, Geosystems, 2007 Detailed characterization of the Mothra Hydrothermal Field, the most southern and spatially extensive field on the Endeavour Segment of the Juan de Fuca Ridge, provides new insights into its geologic and hydrothermal development. Meter‐scale bathymetry, side‐scan sonar imagery, and direct dive observations show that Mothra is composed of six actively ...
