Age, Depth, and Residual Depth Anomalies in the North Pacific: Implications for Thermal Models of the Lithosphere and Upper Mantle [PDF]

, 1986
We present an empirical basement depth versus age relation for the North Pacific Ocean, based on the statistical treatment of an ocean-wide gridded data set.

Magnetic properties of variably serpentinized peridotites and their implication for the evolution of oceanic core complexes [PDF]

, 2014
Serpentinization of ultramafic rocks during hydrothermal alteration at mid-ocean ridges profoundly changes the physical, chemical, rheological, and magnetic properties of the oceanic lithosphere.

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

Tektonika, 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

Geochemistry, 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.

Transfer learning reconstructs submarine topography for global mid-ocean ridges

International 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]

Oceanography, 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

Geochemistry, 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.

Morphology, biostratigraphy, and evolution of PliocenePleistocene diatoms Proboscia barboi.. [PDF]

, 2019
Proboscia barboi and Proboscia curvirostris are two important diatom biostratigraphic markers from the high latitudes of the North Pacific and North Atlantic Oceans, dating back to the Pliocene-Pleistocene time.

Active Long-Lived Faults Emerging Along Slow-Spreading Mid-Ocean Ridges [PDF]

Oceanography, 2012
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.
