Volcanic evolution of an ultraslow-spreading ridge

Nature Communications, 2023
Nearly 30% of ocean crust forms at mid-ocean ridges where the spreading rate is less than 20 mm per year. According to the seafloor spreading paradigm, oceanic crust forms along a narrow axial zone and is transported away from the rift valley.

Modification of Along‐Ridge Topography and Crustal Thickness by Mantle Plume and Oceanic Transform Fault at Ultra‐Slow Spreading Mohns Ridge

Geophysical Research Letters, 2023
The mantle plumes modify geophysical and geochemical features along and across mid‐ocean ridges. Despite abundant studies of plume‐ridge interaction, few geodynamic studies focus on the Arctic Ocean.

The discovery of new deep-sea hydrothermal vent communities in the Southern Ocean and implications for biogeography [PDF]

, 2012
Since the first discovery of deep-sea hydrothermal vents along the Galápagos Rift in 1977, numerous vent sites and endemic faunal assemblages have been found along mid-ocean ridges and back-arc basins at low to mid latitudes.

Hydroacoustic Monitoring of Oceanic Spreading Centers: Past, Present, and Future [PDF]

Oceanography, 2012
Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean.
