Microbiological characterization of post-eruption "snowblower" vents at Axial Seamount, Juan de Fuca Ridge

open access: yesFrontiers 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 ...

Eruptive xanthomas [PDF]

open access: yesAdvances in Dermatology and Allergology, 2013
Xanthomas are localized lipid deposits in the skin, tendons and subcutaneous tissue associated with lipid abnormality. The hyperlipidemia responsible for this disorder can be caused by a primary genetic defect, a secondary disorder, or both. That kind of skin exanthema may be the first signal of cardiovascular risk.

Controls on explosive-effusive volcanic eruption styles

open access: yesNature Communications, 2018
One of the biggest challenges in volcanic hazard assessment is to understand how and why eruptive style changes within the same eruptive period or even from one eruption to the next at a given volcano.

Eruptive dynamics in Plinian silicic eruptions

open access: yes, 2020
Plinian eruptions are characterized by high magma discharge rates and pyroclastic material containing extraordinary large numbers of bubbles. Upon ascent to the surface magma decompresses and volatiles become supersaturated, causing bubbles to nucleate with a rate dependent on the degree of supersaturation.

Rapid eruption of the Columbia River flood basalt and correlation with the mid-Miocene climate optimum

open access: yesScience Advances, 2018
U-Pb ages show Earth’s youngest flood basalt province erupted in 750 ka starting ~16.65 Ma during Miocene global warming. Flood basalts, the largest volcanic events in Earth history, are thought to drive global environmental change because they can emit ...
