The genome of a vestimentiferan tubeworm (Ridgeia piscesae) provides insights into its adaptation to a deep-sea environment [PDF]
BMC Genomics, 2023 Background Vestimentifera (Polychaeta, Siboglinidae) is a taxon of deep-sea worm-like animals living in deep-sea hydrothermal vents, cold seeps, and organic falls.

Microbiological characterization of post-eruption "snowblower" vents at Axial Seamount, Juan de Fuca Ridge [PDF]
Frontiers in Microbiology, 2013 Microbial processes within the subseafloor can be examined during the ephemeral and uncommonly observed phenomena known as snowblower venting. Snowblowers are characterized by the large quantity of white floc that is expelled from the seafloor following ...

A Diverse Community of Metal(loid) Oxide Respiring Bacteria Is Associated with Tube Worms in the Vicinity of the Juan de Fuca Ridge Black Smoker Field. [PDF]
PLoS ONE, 2016 Epibiotic bacteria associated with tube worms living in the vicinity of deep sea hydrothermal vents of the Juan de Fuca Ridge in the Pacific Ocean were investigated for the ability to respire anaerobically on tellurite, tellurate, selenite, selenate ...

Temperature and redox effect on mineral colonization in Juan de Fuca Ridge flank subsurface crustal fluids [PDF]
Frontiers in Microbiology, 2016 To examine microbe-mineral interactions in subsurface oceanic crust, we evaluated microbial colonization on crustal minerals that were incubated in borehole fluids for one year at the seafloor wellhead of a crustal borehole observatory (IODP Hole U1301A,

Influence of Igneous Basement on Deep Sediment Microbial Diversity on the Eastern Juan de Fuca Ridge Flank [PDF]
Frontiers in Microbiology, 2017 Microbial communities living in deeply buried sediment may be adapted to long-term energy limitation as they are removed from new detrital energy inputs for thousands to millions of years.

Distribution of methane-cycling archaea in buried ridge flank sediment: community zonation, activity, and potential environmental drivers [PDF]
Frontiers in MicrobiologySubseafloor sediments harbor Earth’s biggest reservoir of methane, with most of this methane being produced biologically by methanogenic archaea (methanogens).

Oceanic upper crustal accretion by melt sill and lava flow interaction at Axial volcano [PDF]
Nature CommunicationsMagmatically-accreted upper crust along mid-ocean ridges is traditionally considered to consist of lava flows overlying a sheeted-dyke complex. However, how the upper crust is formed at hotspot-influenced ridge segments remains unknown.

Genomics discovery of giant fungal viruses from subsurface oceanic crustal fluids [PDF]
ISME Communications, 2023 The oceanic igneous crust is a vast reservoir for microbial life, dominated by diverse and active bacteria, archaea, and fungi. Archaeal and bacterial viruses were previously detected in oceanic crustal fluids at the Juan de Fuca Ridge (JdFR).

Phylogenetic diversity of microorganisms in subseafloor crustal fluids from boreholes 1025C and 1026B along the Juan de Fuca Ridge flank [PDF]
Frontiers in Microbiology, 2014 To expand investigations into the phylogenetic diversity of microorganisms inhabiting the subseafloor biosphere, basalt-hosted crustal fluids were sampled from Circulation Obviation Retrofit Kits affixed to Holes 1025C and 1026B along the Juan de Fuca ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
