At ocean margins where two plates converge, the oceanic plate sinks or is subducted
beneath an upper one topped by a layer of terrestrial crust. This crust is constructed of …

Mineral dust aerosols in the atmosphere have the potential to affect the global climate by
influencing the radiative balance of the atmosphere and the supply of micronutrients to the …

Abyssal peridotite from the 15° 20′ N area of the Mid-Atlantic Ridge show complex
geochemical variations among the different sites drilled during ODP Leg 209. Major element …

The results of detailed textural, mineral chemical, and petrophysical studies shed new light
on the poorly constrained fluid‐rock reaction pathways during retrograde serpentinization at …

Aqueous dihydrogen (H2, aq) is produced in copious amounts when seawater interacts with
peridotite and H2O oxidizes ferrous iron in olivine to ferric iron in secondary magnetite and …

Serpentinization of abyssal peridotites is known to produce extremely reducing conditions
as a result of dihydrogen (H2, aq) release upon oxidation of ferrous iron in primary phases to …

Abstract The Middle Eocene Climatic Optimum (MECO) was a gradual warming event and
carbon cycle perturbation that occurred between 40.5 and 40.1 Ma. A number of …

Decompressional melting of asthenosphere under spreading centers has been accepted to
produce oceanic lithospheric mantle with vertical compositional variations, but these …

The objective of this study was to enhance our understanding of the fate and trans-Atlantic
transport of dustborne microorganisms from Northern Africa to the Caribbean and Americas …

Abstract The southwestern Barents Sea has experienced profound erosion during the last∼
