Mantle serpentinization and associated hydrogen flux at North Atlantic magma-poor rifted margins

Rifting, lithosphere breakup and volcanism: Comparison of magma-poor and volcanic rifted margins

New models for evolution of magma-poor rifted margins based on a review of data and concepts from West Iberia and the Alps

Direct observation and extensive sampling in ancient margins exposed in the Alps, combined with drillhole and geophysical data from the present-day Iberia margin, result in new concepts for the strain evolution and near-surface response to lithospheric rupturing at magmapoor rifted margins. This paper reviews data and tectonic concepts derived from these two margins and proposes that extension,...

Ocean eddy freshwater flux convergence into the North Atlantic subtropics

Abstract For a quasi steady state condition, the water vapor flux from the ocean to atmosphere typical of the salty subtropics must be compensated by ocean processes that transfer freshwater into the evaporative regime. Observations of the North Atlantic subtropical sea surface salinity maximum region frequently reveal the presence of eddies with distinct salinity/temperature signatures of up t...

Surface Flux Variability over the North Pacific and North Atlantic Oceans

Daily fields obtained from a 17-yr atmospheric GCM simulation are used to study the surface sensible and latent heat flux variability and its relationship to the sea level pressure (SLP) field. The fluxes are analyzed over the North Pacific and Atlantic Oceans during winter. The leading mode of interannual SLP variability consists of a single center associated with the Aleutian low in the Pacif...

Large mantle magma reservoir of Afar, Ethiopia

Most of the Earth’s crust is created at midoceanic ridges where two tectonic plates move away from each other, known as constructive plate boundary system and extends for ∼60,000 km around the globe (Wright et al., 2006). It creates characteristic extensional structures, wherein tectonic stress is primarily released by rifting processes, which thus forms major system of normal faults and volcan...
