First investigation of the microbiology of the deepest layer of ocean crust.
Published 2010-11-01“…The gabbroic layer comprises the majority of ocean crust. Opportunities to sample this expansive crustal environment are rare because of the technological demands of deep ocean drilling; thus, gabbroic microbial communities have not yet been studied. …”

Magnetic Structure of Fast‐Spread Oceanic Crust at Pito Deep
Published 2020-02-01“…Abstract Magnetic surveys at tectonic windows that expose magnetic polarity boundaries provide the unique opportunity to explore the pattern of magnetization variations within the oceanic crust and determine the spatially averaged magnetizations of source layers that contribute to marine magnetic anomalies. …”

Abiotic formation of condensed carbonaceous matter in the hydrating oceanic crust
Published 2018-11-01“…Thermodynamic calculations suggest that condensed carbonaceous matter should be the dominant product of abiotic organic synthesis during serpentinization of the oceanic crust at Mid-Ocean Ridges. Here the authors report natural occurrences of such carbonaceous matter formed during low temperature alteration.…”

Calcium isotope evidence for early Archaean carbonates and subduction of oceanic crust
Published 2021-05-01“…Phase equilibrium modelling combined with Ca isotope measurements in ancient granitoids demonstrates that subduction of oceanic crust occurred repeatedly throughout the Archaean and that carbonate sediments were present in early Eoarchaean oceans (>3.8 billion years).…”
