Thermal and Structural Signatures Associated With Subducted Seamounts in Hyuga‐nada and Off Cape Muroto, Southwest Japan

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present heat flow estimates beneath the forearc slopes off Hyuga‐nada and Cape Muroto in the Nankai Trough, where the Philippine Sea plate subducts beneath the southwestern Japan. Using seismic reflection data, we identified Bottom Simulating Reflectors and derived heat flow ranging from 20 to >140 mW/m2.

Improved Half‐Space Cooling Model Reconciles Bathymetry and Thermal Evolution of the Southwest Subbasin, South China Sea

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The bathymetry of marginal sea basins commonly deviates from depths calculated by classical lithospheric cooling models, yet the controlling mechanisms remain debated. Here, using 19 seismic profiles and corrected local heat‐flow data, we apply an improved half‐space cooling model within a two‐stage reconstruction to reassess thermal ...

Annual Carbon Export at the North Pacific Axial Seamount

open access: yes, 2019
As anthropogenic CO2 levels rise, it becomes increasingly important to quantify the flux from the surface ocean down into the deep, where it may be sequestered for thousands of years.

Does the Zhenbei seamount in the South China Sea harbor distinctive biodiversity? A primary study based on eDNA metabarcoding

open access: yesGlobal Ecology and Conservation
The South China Sea is one of the regions with the richest marine biodiversity in the world, featuring a variety of ecological environment such as deep-sea plains, seamounts, and cold springs. Currently, studies on the biodiversity of the South China Sea

An Overview of Seabed Mining Including the Current State of Development, Environmental Impacts, and Knowledge Gaps

open access: yesFrontiers in Marine Science, 2018
Rising demand for minerals and metals, including for use in the technology sector, has led to a resurgence of interest in exploration of mineral resources located on the seabed.

The Impact of Double Subduction on Plate Velocity and Euler Pole Shifts: Insights From Spherical Subduction Models

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐scale spherical geometry ...

Linking Tectonics and Cratonic Vertical Motions: Deep‐Time Thermochronology Reveals >1,000 Myr of Low‐Temperature Conditions in Southeastern Finland

open access: yesTectonics, Volume 45, Issue 9, September 2026.
Abstract The Fennoscandian Shield potentially hosts the longest continuous habitable conditions for Earth's deep biosphere. Billion‐year equilibrium freeboard conditions of cratons and the longevity of deep biosphere microbial communities are directly related through the thermal histories of rocks that host these communities.

Relationship between viral and prokaryotic abundance on the Bajo O’Higgins 1 Seamount (Humboldt Current System off Chile)

open access: yesScientia Marina, 2007
There is little known about the ecology of microbial communities living in the water column over seamounts. Here, for the first time, the spatial distribution and abundance of virus-like particles (VLP) are described over a seamount.

Deep blueprint: A literature review and guide to automated image classification for ecologists

open access: yesJournal of Animal Ecology, Volume 95, Issue 9, Page 1558-1585, September 2026.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Physiography of the Ampère Seamount in the Horseshoe Seamount chain off Gibraltar

open access: yes, 2005
The Ampère Seamount, 600 km west of Gibraltar, is one of nine inactive volcanoes along a bent chain, the so called Horseshoe Seamounts. All of them ascend from an abyssal plain of 4000 to 4800 m depth up to a few hundred meters below the sea surface ...
