Spotlight 5: Great Meteor Seamount [PDF]

Oceanography, 2010
Great Meteor Seamount is one of the largest seamounts in the Atlantic Ocean, rising from 4200-m depth at the seafloor to 270-m depth beneath the sea surface. Its elliptical plateau encompasses an area of 1500 km2, roughly matching the size of the Spanish

The complete mitochondrial genome of a deep sea ophiuroid of the genus Amphiura (Ophiuroidea: Amphiuridae)

Mitochondrial DNA. Part B. Resources, 2019
Amphiura is a widely distributed genus of Ophiuroidea from various environment, play an important role in evolution. Here, we reported a complete mitochondrial genome of Amphiura sp. which was collected from a deep sea seamount in the West Pacific.

Detection of Shallow Tectonic Tremors in Hyuga‐nada, Nankai Trough, Using the Newly Established N‐Net OBS Network

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Monitoring tectonic tremors is crucial for understanding stress release in subduction zones and assessing megathrust earthquake risk. The Hyuga‐nada region, at the western edge of the Nankai Trough, Japan, provides a natural laboratory for investigating links among slow earthquakes, megathrust events, and complex subduction structures.

Examining Controls on Fluid Overpressure in Buried Basement Highs of Oceanic Crust: Implications for Permeability of the Astoria Fan

Geochemistry, Geophysics, Geosystems
Vigorous hydrothermal circulation in the basement aquifer of the oceanic crust homogenizes temperatures within the aquifer and generates fluid overpressures at the tops of buried basement highs.

Topographic Anchoring and the “Silent Period” of Deep‐Water Polynyas in the 90°W–90°E Antarctic Sector

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Antarctic deep‐water polynyas act as critical windows driving deep ocean ventilation, exerting profound impacts on the global thermohaline circulation and biogeochemical cycles. Utilizing high‐resolution satellite remote sensing and ocean reanalysis data from 2003 to 2022, this study identified eight recurring deep‐water polynyas within the ...

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

Geochemistry, Geophysics, Geosystems
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 ...

Undersea volcano production versus lithospheric strength from satellite altimetry [PDF]

All seamount signatures apparent in the SEASAT altimeter profiles were located and digitized. In addition to locating the seamount signatures, their amplitudes were also estimated. The second phase consisted of determining what basic characteristics of a
