Hydrothermal Chimney Distribution on the Endeavour Segment, Juan de Fuca Ridge [PDF]

open access: yesGeochemistry, 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]

open access: yesGeochemistry, 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 ...

Systematic shift in plume bending direction at Grotto Vent, Main Endeavour Field, Juan de Fuca Ridge implies changes in venting output along the Endeavour Segment

open access: yesFrontiers in Earth Science, 2022
Analysis of the time-dependent behavior of the buoyant plume rising above Grotto Vent (Main Endeavour Field, Juan de Fuca Ridge) as imaged by the Cabled Observatory Vent Imaging Sonar (COVIS) between September 2010 and October of 2015 captures long term ...

Near‐axis crustal structure and thickness of the Endeavour Segment, Juan de Fuca Ridge [PDF]

open access: yesGeophysical 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]

open access: yesOceanography, 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 ...

Low-Temperature Hydrothermal Plumes in the Near-Bottom Boundary Layer at Endeavour Segment, Juan de Fuca Ridge [PDF]

open access: yesOceanography, 2012
Low-temperature (typically 5–75°C) fluid, commonly referred to as "diffuse" hydrothermal flow, emanates from fractures over a significant portion of the Juan de Fuca Ridge seafloor in the Northeast Pacific Ocean (Kelley et al., 2012, in this issue ...

Dispersion of deep-sea hydrothermal plumes at the Endeavour Segment of the Juan de Fuca Ridge: a multiscale numerical study

open access: yesFrontiers in Marine Science, 2023
A multiscale numerical framework has been developed to investigate the dispersion of deep-sea hydrothermal plumes that originate from the Endeavour Segment of the Juan de Fuca Ridge located in the Northeast Pacific.

Hydrothermal Chimney Weathering Time Series, Endeavour Segment, Juan de Fuca Ridge: The view from the sulfur edge

open access: yesGoldschmidt2023 abstracts, 2023
We used synchrotron micro X-ray fluorescence (µXRF) imaging, micro X-ray absorption near-edge structure (µXANES) and micro X-ray diffraction (µXRD) to analyze a transect of hydrothermal chimney samples from the Endeavour Ridge segment of the Juan de Fuca

Spreading Dynamics of an Intermediate Ridge: Insights from U-series Disequilibria, Endeavour Segment, Juan de Fuca Ridge [PDF]

open access: yesJournal of Petrology, 2018
We present new U-series disequilibria results for 37 basalts collected from the flanks and axial valley of the Endeavour segment of the Juan de Fuca Ridge, making Endeavour one of the most wellcharacterized spreading ridges along the global ridge system.

Recent Seismic Studies at the East Pacific Rise 8°20'–10°10'N and Endeavour Segment: Insights into Mid-Ocean Ridge Hydrothermal and Magmatic Processes [PDF]

open access: yesOceanography, 2012
As part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise (EPR) 8°20'–10°10'N and Endeavour Segment of the Juan de Fuca ...
