OBS Data Mining Reveals Seismic Structure and Dynamics of the Oceanic Blanco Transform Fault, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.

Flux and Isotopic Composition of Sedimentary Carbon Subducting Along the World's Trenches

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Here we provide comprehensive estimates for the subducted sedimentary flux of inorganic and organic carbon and δ13C at 16 trench segments worldwide. Our calculations provide minimum (incoming sediment), maximum (trench fill) and best estimates (underthrust) of carbon fluxes.

Petrological variability of recent magmatism at Axial Seamount summit, Juan de Fuca Ridge

Geochemistry, Geophysics, Geosystems, 2013
A combined study of mapping, observational, age constraint, and geochemical data at the summit of Axial Seamount, Juan de Fuca Ridge, has revealed its recent petrological history. Multiple basalt types erupted at the summit in a time sequence.

Tidal triggering of microearthquakes on the Juan de Fuca Ridge

Geophysical Research Letters, 2001
Tidal stresses beneath the oceans can be up to an order of magnitude higher than those found in the continents because of the effects of loading by ocean tides. I have analyzed 1899 microearthquakes recorded during a 55‐day experiment on the Endeavour segment of the Juan de Fuca Ridge for tidal triggering.

Seismicity, Repeating Earthquakes, and Tomographic Imaging of the Blanco Transform Fault System, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

Geology of the Northern End of Juan de Fuca Ridge and Sea-Floor Spreading

, 1974
The northern end of Juan de Fuca Ridge consists of a series of basement ridges and valleys, inundated with sediment except for the axis of most recent sea-floor spreading.

Mid‐Ocean Ridge (MOR) Ash Dispersal on Axial Seamount, Juan de Fuca Ridge

Geochemistry, Geophysics, Geosystems
Rare eruption of primitive normal mid‐ocean ridge basalt (N‐MORB) magma (∼9.5 wt% MgO) on the summit of Axial Seamount generated abundant ash that was dispersed for several km.

Fate of event hydrothermal plumes on the Juan de Fuca Ridge

Geophysical Research Letters, 1995
Current meter moorings were deployed in August 1993 at the megaplume site of the June 1993 seismic event on the CoAxial segment of the Juan de Fuca Ridge and were recovered in April 1994. Record‐averaged flow was about 2 cm/s across axis, which is sufficiently large to advect plumes off axis in a few days.
