The draft genome of the hyperthermophilic archaeon Pyrodictium delaneyi strain hulk, an iron and nitrate reducer, reveals the capacity for sulfate reduction

open access: yesStandards in Genomic Sciences, 2017
Pyrodictium delaneyi strain Hulk is a newly sequenced strain isolated from chimney samples collected from the Hulk sulfide mound on the main Endeavour Segment of the Juan de Fuca Ridge (47.9501 latitude, −129.0970 longitude, depth 2200 m) in the ...

Four-Hundred-and-Ninety-Million-Year Record of Bacteriogenic Iron Oxide Precipitation at Sea-Floor Hydrothermal Vents [PDF]

open access: yes, 2004
Fe oxide deposits are commonly found at hydrothermal vent sites at mid-ocean ridge and back-arc sea floor spreading centers, seamounts associated with these spreading centers, and intra-plate seamounts, and can cover extensive areas of the seafloor ...

Halos of Enhanced Sediment Alteration Above Buried Seamounts Approaching the Cascadia Subduction Zone

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Sediment thermal history controls the progress of diagenetic reactions that can alter the mechanical behavior of material entering a subduction zone that then: accretes to the margin, hosts the plate boundary interface, or is carried deeper within the Earth.

The Biggest Plates on Earth: Plate Tectonics [PDF]

open access: yes
In this lesson, students investigate the movement of Earth's tectonic plates, the results of these movements, and how magnetic anomalies present at spreading centers document the motion of the crust. As a result of this activity, students will be able to

All Aligned on the Western Front of North America? Analyzing the Stress Field in the Northern Cordillera

open access: yesTectonics, Volume 44, Issue 9, September 2025.
Abstract This study presents the first rigorous statistical analysis of the present‐day crustal stress along the western margin of the North American Plate, covering the entire Canadian Cordillera and Alaska. Using circular statistics and geometric tests, we develop a regional stress province model that constrains the directions of first‐order stresses.

Analysis of Off-axis, Low-velocity Zones on the Flanks of the Endeavour Segment of the Juan de Fuca Ridge [PDF]

open access: yes, 2012
Seismic data from the intermediate-spreading Endeavour segment of the Juan de Fuca Ridge reveal several crustal-level, low-velocity, high-attenuation regions on the eastern and western ridge flanks 7 to 16 km from the neovolcanic zone.

Assessment of slope failures off Vancouver Island revealed in EM300 multibeam bathymetry data [PDF]

open access: yes, 2016
Multibeam bathymetric data acquired off Vancouver Island across the accretionary prism of the Cascadia subduction zone reveal a prominent segmentation of the deformation front with dominant azimuths of the ridges at ~120° and ~150° and abundant submarine
