The geodynamics of plume-influenced mid-ocean ridges: insights from the Foundation Segment of the Pacific-Antarctic Ridge Open
The intersection of the Foundation Plume with the Pacific-Antarctic Ridge is a key location in global geodynamics where a mantle plume is approached by and interacting with a fast-spreading mid-ocean ridge. Here, we discuss a comprehensive…

Numerical fluid flow modelling in the context of CO2 sequestration on mid-ocean ridge flanks Open
The majority of Earth’s basaltic volcanism occurs at mid-ocean ridges, where new ocean floor is created. Especially young oceanic crust, which is highly porous and permeable, is subject to regional off-axis hydrothermal circulation, …

Smokers under stress: new insights into the tectonic, magmatic and oceanic modulation of hydrothermal discharge at mid-ocean ridges Open
Hydrothermal systems along mid-ocean ridges (MORs) are a crucial interface between Earth’s deep interior, the seafloor, and the overlying ocean. Although hydrothermal systems are typically thought of as steady-state flow environments…

Lithospheric Structure Controls Sequentially Active Detachment Faulting at the Longqi Segment on the Southwest Indian Ridge Open
Oceanic detachment faulting, a major mode of seafloor accretion at slow and ultraslow spreading ridges, is thought to occur during magma‐poor phases and be abandoned when magmatism increases. In this framework, detachment faulting is the r…

Hidden periodic states in gas hydrate systems lead to spontaneous gas release without external triggers Open
Gas hydrates are one of the largest marine carbon reservoirs on Earth. The conventional understanding of hydrate dynamics assumes that the system converges to a steady-state over geological time-scales, achieving fixed concentrations of ga…
