Magmatic activity at the slowest spreading rates: insights from a high-resolution earthquake catalog obtained from Gakkel Ridge Deep (Arctic Ocean)

Seismica
At the eastern end of Gakkel Ridge, Arctic Ocean, spreading rates drop below 5 mm/y near the termination of the active mid-ocean ridge in the Laptev Sea.

Earthquake Seismicity Reveals the Location and Significance of the Shona Mantle Plume in the South Atlantic Ocean

Geophysical Research Letters
The South Atlantic Ocean hosts several well‐studied volcanic ridges and seamount chains, but the origin of their associated mantle plumes is debated.

Speed matters - seismicity and spreading processes of ultraslow spreading mid-ocean ridges [PDF]

, 2018
The creation of new ocean lithosphere at mid-ocean ridges is accompanied by characteristic earthquake activity. The analysis of mid-ocean ridge seismicity proved a powerful tool to study submarine accretion of lithosphere and the structure of mid-ocean ...

Seismic stratigraphy and history of deep circulation and sediment drift development in Baffin Bay and the Labrador Sea [PDF]

, 1989
Drilling results and seismic-reflection records at and across Ocean Drilling Program (ODP) Sites 645 (western Baffin Bay), 646, and 647 (Labrador Sea) provide important constraints on the history of deep-water circulation and sedimentation in response to

Subducted Carbon From Mantle Plume in Mid‐Ocean Ridge Basalts

Geophysical Research Letters
Deciphering the Earth's deep carbon cycle, from mantle plumes to mid‐ocean ridges, remains incompletely understood. In this study, we analyze the magnesium isotope composition of basalts collected from the South Mid‐Atlantic Ridge (SMAR), which have been

Rapid transition from continental breakup to igneous oceanic crust in the South China Sea [PDF]

, 2018
Continental breakup represents the successful process of rifting and thinning of the continental lithosphere, leading to plate rupture and initiation of oceanic crust formation.
