The age structure of the global ocean floor is a key feature in paleogeographic reconstructions, which in turn forms the quantitative basis for Earth System Science.

Transfer learning reconstructs submarine topography for global mid-ocean ridges
Mid-ocean ridges are unique, tectonically active geographical units on Earth that profoundly control the ocean environment and dynamics at the global scale.

Geodynamic Models of Melt Generation and Extraction at Mid-Ocean Ridges [PDF]
It is widely accepted that plate divergence at mid-ocean ridges drives mantle flow, mantle melting, and the formation of new oceanic crust. However, many of the details of this process remain obscure because of the inaccessibility of the mantle to direct

A Highly Depleted and Subduction‐Modified Mantle Beneath the Slow‐Spreading Mohns Ridge
The Mohns Ridge is a very slow‐spreading ridge that, together with the Knipovich Ridge, marks the boundary between the North American and Eurasian plates in the Norwegian‐Greenland Sea.

Active Long-Lived Faults Emerging Along Slow-Spreading Mid-Ocean Ridges [PDF]
In the classic mid-ocean ridge model, new seafloor is generated through a combination of magmatic diking feeding lava flows at the spreading axis, and the formation of short-offset, high-angle normal faults that dip toward the axis.

Radiocarbon constraints on the extent and evolution of the South Pacific glacial carbon pool
On glacial/interglacial timescales CO2 might have been sequestered from the atmosphere and stored within the deep ocean. Here, the authors show that an old and CO2-rich water mass occupied the glacial South Pacific between ∼2,000 and 4,300 m water depth ...

Hydrothermal Discharge During Submarine Eruptions: The Importance of Detection, Response, and New Technology [PDF]
Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to ...

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

The population divergence process of deep-sea vent invertebrates is driven by both biotic (e.g., dispersal during the larval stage) and abiotic factors such as deep-ocean currents, depth, and the geological setting of vents.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.
