Rotating horizontal convection with meridional ridges

open access: yesFrontiers in Marine Science, 2022
According to recent studies, the large-scale effect of bottom topography on the ocean overturning circulation can be considered as a result of bottom enhancement of turbulent mixing in the abyssal ocean.

Geophysical characterisation of the ocean–continent transition at magma-poor rifted margins [PDF]

open access: yes, 2009
Geophysical characterisation of the ocean-continent transition (OCT) at magma-poor riftedmargins has focused primarily on the determination of P wave velocities using wide-angleseismic techniques. Such experiments have shown that the OCT is heterogeneous,

MORGen: an Algorithm to Compute Spreading Centre and Transform Geometries from Simple Initial Plate Boundaries and Euler Rotations

open access: yesTektonika, 2023
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.

Crystallization of Superfast‐Spreading Oceanic Crust (ODP Hole 1256D, Pacific Ocean): Constraints From Zircon Geochronology

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Studies of oceanic crust, which covers a large proportion of the Earth's surface, have provided significant insight into the dynamics of crustal accretion processes at mid‐ocean ridges.

Evidence for a reducing Archean ambient mantle and its effects on the carbon cycle [PDF]

open access: yes, 2016
Chemical reduction-oxidation mechanisms within mantle rocks link to the terrestrial carbon cycle by influencing the depth at which magmas can form, their composition, and ultimately the chemistry of gases released into the atmosphere.

Transfer learning reconstructs submarine topography for global mid-ocean ridges

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
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]

open access: yesOceanography, 2012
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

open access: yesGeochemistry, Geophysics, Geosystems, 2022
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.
