Earthquake swarms on the Mid-Atlantic Ridge: assessing the applicability of a global catalogue for seismic analysis

Frontiers in Earth Science
The Mid-Atlantic Ridge is mostly positioned at great distances from on-land seismic stations. As a result, analyses of earthquakes are challenging, with focused studies often coming through temporary local recording devices.

RRS "Charles Darwin" Cruise 169, 17 Feb-19 Mar 2005. Hydrothermal exploration of the southern Mid-Atlantic Ridge [PDF]

, 2006
The principal objective of this cruise was to identify the first site or sites of high temperature hydrothermal venting anywhere on the southern Mid-Atlantic Ridge, to characterize their geological setting, preliminary chemical nature and to identify ...

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.

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)

International Journal of Climatology, EarlyView.
This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.

Deep Water Exchange Through Fracture Zones In The North Atlantic Ridge, Central Atlantic

Russian Journal of Earth Sciences
The study investigates the properties of deep and bottom waters in four previously unexplored fracture zones of the Mid-Atlantic Ridge located between 24° N and 36° N.

Metals in the shell of Bathymodiolus azoricus from a hydrothermal vent site on the Mid-Atlantic Ridge [PDF]

, 2007
Specimens of the mussel Bathymodiolus azoricus were collected from Menez Gwen, a relatively shallow (850 m) hydrothermal vent field on the Mid-Atlantic Ridge. Each bivalve shell (n = 21) was individually cleaned by selective chemical.

Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires

International Journal of Climatology, EarlyView.
Extreme wildfires in the Pantanal in 2024 were driven by a cascade of heatwaves, rainfall deficits and the absence of the annual flood pulse. These conditions dried soils and rivers, enhanced fuel accumulation and enabled early and intense fire outbreaks.

Alaskan Ridge Blocking and Associated Winter Cold Conditions Over North America

International Journal of Climatology, EarlyView.
Multi‐decadal (1979–2023) analysis reveals that wintertime reductions in the meridional gradient of potential vorticity (PVy) over the Bering Sea are recurrent but episodic features of North Pacific circulation. These suppressed PVy states consistently co‐occur with amplified Alaskan ridging, weakened mid‐tropospheric westerlies and a downstream warm ...

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...
