Morphology and tectonics of the Mid-Atlantic Ridge, 7°–12°S

open access: yes, 2003
We present swath bathymetric, gravity, and magnetic data from the Mid-Atlantic Ridge between the Ascension and the Bode Verde fracture zones, where significant ridge–hot spot interaction has been inferred.

Roots [PDF]

open access: yesOceanography, 2012
It is with especially great pleasure, and a bit of nostalgia, that I introduce the March 2012 special issue of Oceanography on "Oceanic Spreading Center Processes: Ridge 2000 Program Research." My very first oceanographic cruise was to the Juan de Fuca ...

A 20-Year Hydroacoustic Time Series of Seismic and Volcanic Events in the Northeast Pacific Ocean [PDF]

open access: yesOceanography, 2011
For the last 20 years, civilian researchers have used the Sound Surveillance System (SOSUS), a US Navy hydrophone array deployed for anti-submarine warfare during the Cold War, to detect seismic and volcanic activity in the Northeast Pacific Ocean.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Numerical modeling of phase separation at Main Endeavour Field, Juan de Fuca Ridge

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Before being disrupted by a magmatic event in 1999, the vent temperatures and salinities along the axis of the Main Endeavour Field on the Juan de Fuca Ridge exhibited a quasi‐steady spatial gradient in which the southern vent fluids were hotter and less

Generation of Channelized Mantle Flow Beyond the Rift Zone Accelerated by Thermal Heterogeneity and Rift Propagation

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis can influence magmatism and deformation beyond the rift zone.

Juan de Fuca Ridge atlas, SeaMARC II acoustic imagery

open access: yes, 1984
This open file comprises approximately 15,000 km2 of SeaMARC II side-scan acoustic imaging data from the northern Juan de Fuca and Explorer Ridges. These data are presented in two formats: a mosaic at a scale of 1:250,000 and individual swath images (10 ...
