A 20-Year Hydroacoustic Time Series of Seismic and Volcanic Events in the Northeast Pacific Ocean [PDF]
Oceanography, 2011 For the last 20 years, civilian researchers have used the Sound Surveillance System (SOSUS), a US Navy hydrophone array deployed for anti-submarine warfare during the Cold War, to detect seismic and volcanic activity in the Northeast Pacific Ocean.

Numerical modeling of phase separation at Main Endeavour Field, Juan de Fuca Ridge
Geochemistry, Geophysics, Geosystems, 2013 Before being disrupted by a magmatic event in 1999, the vent temperatures and salinities along the axis of the Main Endeavour Field on the Juan de Fuca Ridge exhibited a quasi‐steady spatial gradient in which the southern vent fluids were hotter and less

Sr isotopic variations along the Juan de Fuca Ridge
Journal of Geophysical Research: Solid Earth, 1984 Sr isotopic ratios of 39 glass and microcrystalline basalt samples along the Juan de Fuca Ridge and 1 glass sample from Brown Bear Seamount are at the lower end of the range for normal mid‐oceanic ridge basalt (MORB); the average 87Sr/86Sr ratio is 0.70249±0.00014 (2‐σ). Although subtle variations exist along strike of the ridge, the Sr isotope data do
