Hydrothermal circulation and alteration at mid-ocean ridges and ridge flanks have a key role
in regulating seawater chemistry and global chemical fluxes, and support diverse …

Our understanding of Earth's rock-hosted subsurface biosphere has advanced over the past
two decades through the collection and analysis of fluids and rocks from aquifers within the …

Marine pollution presents a pressing environmental issue in the oceanic realm. To examine
the identification, detection, and mitigation technologies employed for marine pollution, a …

The lithified lower oceanic crust is one of Earth's last biological frontiers as it is difficult to
access. It is challenging for microbiota that live in marine subsurface sediments or igneous …

Abstract The Oman Drilling Project established an “Active Alteration” multi‐borehole
observatory in peridotites undergoing low‐temperature serpentinization in the Samail …

Alkaline fluids venting from chimneys of the Lost City hydrothermal field flow from a
potentially vast microbial habitat within the seafloor where energy and organic molecules …

The Lost City hydrothermal field is a dramatic example of the biological potential of
serpentinization. Microbial life is prevalent throughout the Lost City chimneys, powered by …

Serpentinites are central to water (re) cycling in subduction zones and thus effect fluid-
mediated element transfer between the hydrosphere and the Earth's mantle and back into …

The hydrous alteration of ultramafic rocks, known as serpentinization, generates fluids that
can fuel microbial communities and enable the synthesis of simple organic compounds …

Deep-sea hydrothermal fluids are often enriched in carbon dioxide, methane, and hydrogen.
Methane effuses from metal-rich black smokers such as the Rainbow hydrothermal field, at …
