Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Mid-Ocean Ridge and Storm Enhanced Mixing in the Central South Atlantic Thermocline
We investigate the spatial distribution of diapycnal mixing and its drivers in the central South Atlantic thermocline between the Rio-Grande Rise to the Mid-Atlantic Ridge.

The permeability, connectivity, and reactivity of fluid reservoirs in oceanic crust are poorly constrained, yet these reservoirs are pathways for about a quarter of the Earth's heat loss, and seawater‐rock exchange within them impact ocean chemical ...

The Energetic 2022 Seismic Unrest Related to Magma Intrusion at the North Mid‐Atlantic Ridge
A seismic swarm affected the 53.3°–54.3° Latitude North section of the Mid‐Atlantic Ridge from 26 September to 10 December 2022. We rely on regional, teleseismic and array data to relocate 61 hypocenters and derive 77 moment tensors.

South Scandinavian joints and Alpine/Atlantic-ridge tectonics
Field observations and studies of the joints and dykes in an area shed light on its younger tectonic development; thus, joint orientations measured in Southern Sweden and in Norway have been statistically studied and compared regarding their tectonic ...

Lebensspuren of the Bathyal Mid-Atlantic Ridge [PDF]
The extent of megafaunal bioturbation was characterised at flat sedimented sites on the Mid-Atlantic Ridge (MAR) at 2500 m depth. This study investigated the properties of and spatial variation in surficial bioturbation at the MAR. Lebensspuren assemblages were assessed at four superstations either side of the MAR and in two different surface ...

In the South Atlantic, a reorganization of the Mid‐Atlantic Ridge began before anomaly C34n (83.6 Ma) and ended before anomaly C30n (66.4 Ma), complicating tectonics of Rio Grande Rise and older Walvis Ridge (WR), which formed together at the Mid ...

Changes in water mass composition and circulation in the central Arctic Ocean between 2011 and 2021 inferred from tracer observations [PDF]
The Arctic Ocean is changing rapidly and Atlantic Water circulation plays a key role in the warming, sea-ice decline, and ecosystem changes observed in the Arctic.

Global variation of seismic energy release with oceanic lithosphere age
Variations in Mid Ocean Ridge seismicity with age provide a new tool to understand the thermal evolution of the oceanic lithosphere. The sum of seismic energy released by earthquakes during a time, and for an area, is proportional to its lithospheric age.
