Seafloor Displacements Across the Mid‐Ocean Ridge Eruption Cycle Modulated by Mush Zone Viscosity
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Mid‐ocean ridges (MORs) are active volcanic systems where axial magma lenses (AMLs) are replenished on decadal time scales, enabling frequent dike intrusions. The associated seafloor deformation, however, remains scarcely understood. Here we assess this deformation by simulating cycles of steady AML inflation followed by instantaneous dike ...

Hydrothermal Deposition on the Juan De Fuca Ridge Over Multiple Glacial–interglacial Cycles
, 2019 Hydrothermal systems play an important role in modern marine chemistry, but little is known about how they may have varied on 100,000 year timescales. Here we present high-resolution records of non-lithogenic metal fluxes within sediment cores covering ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Porosity and permeability are crucial factors influencing hydrothermal flow in the oceanic crust. This paper provides a comprehensive overview of measurements and estimates of porosity and permeability. Although scientific drilling projects have yielded direct measurements of these properties, available data remain limited, particularly for ...

Axial seamount: An active ridge axis volcano on the Central Juan De Fuca Ridge
, 1990 Axial Seamount (some of the manuscripts in this special section refer to the edifice with the more precise name of "Axial Volcano"), a large ridge axis volcano, is located on the central segment of the Juan de Fuca Ridge approximately 250 nautical miles ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.Abstract Mid‐ocean ridges, the Earth's most extensive volcanic system, exhibit unique characteristics in sediment‐dominant environments. Thick sediment cover insulates the crust and channels fluid along pathways that can lead to the formation of distinct crustal alteration patterns, exceptionally large mineral deposits, and specialized chemosynthetic ...

Reproductive ecology of Vestimentifera (Polychaeta: Siboglinidae) from hydrothermal vents and cold seeps [PDF]
, 2005 Giant siboglinid tubeworms (formerly Vestimentifera) are ecologically important members of deep-sea chemosynthetic communities, including hydrothermal vents and cold seeps.

Polychromatic Population of Bioluminescent Organisms in the Deep Pacific Ocean
Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.Abstract We present a comprehensive study of deep‐sea bioluminescent organisms in the Cascadia Basin, Northeast Pacific Ocean, based on four years (2020–2023) of in situ measurements using STRings for Absorption length in Water instruments. Analysis of over 1.3 million camera images and continuous photomultiplier tube recordings revealed that ...
