The January 1998 Earthquake swarm at Axial Volcano, Juan de Fuca Ridge: Hydroacoustic evidence of seafloor volcanic activity
On January 25, 1998 at 11:33Z, an intense swarm of earthquakes began within the summit caldera of Axial Volcano, central Juan de Fuca Ridge (JdFR). The earthquake swarm was detected using the U.S.Expand
Seasonal and Geographic Variation of Southern Blue Whale Subspecies in the Indian Ocean
The geographic and seasonal occurrence of different blue whale acoustic populations using one year of passive acoustic recording from three sites located at different latitudes in the Indian Ocean indicates the importance of the area for blue whales in these former whaling grounds. Expand
Seasonal occurrence of north atlantic right whale (Eubalaena Glacialis) vocalizations at two sites on the scotian shelf
A year-long acoustic survey for critically endangered North Atlantic right whales was conducted at two sites on the central and western Scotian Shelf. Autonomous hydrophones recorded soundExpand
Earthquake-induced changes in a hydrothermal system on the Juan de Fuca mid-ocean ridge
Measurements of hydrothermal vent temperature from several vents on the Juan de Fuca ridge in June 1999 are reported, showing a large, segment-wide thermal response to relatively modest tectonic activity, which raises questions about the sources of excess heat and fluid, and the possible effect on vent biological communities.

Acoustic detection of a seafloor spreading episode on the Juan de Fuca Ridge using military hydrophone arrays
Until recently, no practical method has been available to continuously monitor seismicity of seafloor spreading centers. The availability of the U.S. Navy's SOund SUrveillance System (SOSUS) forExpand
The June‐July 1993 seismo‐acoustic event at CoAxial segment, Juan de Fuca Ridge: Evidence for a lateral dike injection
The CoAxial segment (Juan de Fuca Ridge) was the site of an intense swarm of earthquakes that began at 21:43 GMT on June 26, 1993 (Julian Day 177). The swarm started near 46°15′N and migratedExpand
Low-frequency whale and seismic airgun sounds recorded in the mid-Atlantic Ocean.
Whales were detected by these hydrophones despite its location in a very remote part of the Atlantic Ocean that has traditionally been difficult to survey, due to its location near the Mid-Atlantic Ridge. Expand

Aftershock sequences in the mid-ocean ridge environment: an analysis using hydroacoustic data
Abstract Hydroacoustic data from autonomous arrays and the U.S. Navy's Sound Surveillance System (SOSUS) provide an opportunity to examine the temporal and spatial properties of seismicity alongExpand
