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

open access: yesGeochemistry, 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.

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

open access: yesJournal 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.

Seismic Stratigraphy and Tectonic Evolution of the Forearc Georgia Basin (Upper Cretaceous–Miocene), Canada and USA, With Implications for CO2 Sequestration

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
2D seismic and well data reveal multi‐phase basin filling in the Whatcom Sub‐Basin shaped by syn‐depositional tectonism. An Eocene transition from forearc basin to forearc depression corresponds to decreasing normal‐fault density and throw, both upsection and eastward. Paleogene–Neogene strata are the best CO2 storage targets.

Beyond the ocean frontier: the Juan de Fuca Ridge

open access: yes, 1986
Two thousand metres below the surface of the Pacific Ocean off Canada's west coast is an underwater mountain range called the Juan de Fuca Ridge. Its steaming vents spew forth an abundance of molten minerals, supporting a unique ecosystem denied the ...

Assessment of decadal-scale ecological change at a deep Mid-Atlantic hydrothermal vent and reproductive time-series in the shrimp Rimicaris exoculata [PDF]

open access: yes, 2007
This study presents a comparison of distribution and abundance of dominant megafaunal species at the TAG hydrothermal mound on the Mid-Atlantic Ridge from 1994 to 2004.

Characterizing the Unique Chemical Imprint of On‐Axis, Lower‐Temperature Hydrothermal Flow to the Deep Ocean (Southern East Pacific Rise, 16.5°–18.0°S)

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract In addition to high‐temperature vents, lower‐temperature flow (LTF) (<300°C) is abundant along mid‐ocean ridges and contributes globally‐important fluxes of heat and water along with largely‐unconstrained geochemical influences on the ocean. We examined the impact of on‐axis LTF on the chemical composition of the overlying water column (<40 m ...

Biogeography and evolution of Thermococcus isolates from hydrothermal vent systems of the Pacific

open access: yesFrontiers in Microbiology, 2015
Thermococcus is a genus of hyperthermophilic archaea that is ubiquitous in marine hydrothermal environments growing in anaerobic subsurface habitats but able to survive in cold oxygenated seawater.

Carbon fixation by basalt-hosted microbial communities

open access: yesFrontiers in Microbiology, 2015
Oceanic crust is a massive potential habitat for microbial life on Earth, yet our understanding of this ecosystem is limited due to difficulty in access. In particular, measurements of rates of microbial activity are sparse. We used stable carbon isotope
