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 ...

Triggering of eruptions at Axial Seamount, Juan de Fuca Ridge. [PDF]
Sci Rep, 2020 AbstractThe submarine volcano Axial Seamount has exhibited an inflation predictable eruption cycle, which allowed for the successful forecast of its 2015 eruption. However, the exact triggering mechanism of its eruptions remains ambiguous. The inflation predictable eruption pattern suggests a magma reservoir pressure threshold at which eruptions occur,

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.

Linkages between mineralogy, fluid chemistry, and microbial communities within hydrothermal chimneys from the Endeavour Segment, Juan de Fuca Ridge. [PDF]
Geochem Geophys Geosyst, 2016 Rock and fluid samples were collected from three hydrothermal chimneys at the Endeavour Segment, Juan de Fuca Ridge to evaluate linkages among mineralogy, fluid chemistry, and microbial community composition within the chimneys.

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.

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.

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).

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).
