In the face of dramatic declines in groundfish populations and a lack of sufficient stock assessment information, a need has arisen for new methods of assessing groundfish populations. We describe the integration of seafloor transect data gathered by a manned submersible with high-resolution sonar imagery to produce a habitat- based...
NW Rota-1 is a submarine volcano in the Mariana volcanic arc located ~100 km north of Guam.
Underwater explosive eruptions driven by magmatic gases were first witnessed there in 2004 and continued
until at least 2010. During a March 2010 expedition, visual observations documented continuous but
variable eruptive activity at...

We present multiple lines of evidence for years to decade-long changes in the location and
character of volcanic activity at West Mata seamount in the NE Lau basin over a 16 year period, and a hiatus
in summit eruptions from early 2011 to at least September 2012. Boninite lava and...

The eruption of South Sarigan Seamount in the southern Mariana arc
in May 2010 is a reminder of how little we know about the hazards associated with
submarine explosive eruptions or how to predict these types of eruptions. Monitored
by local seismometers and distant hydrophones, the eruption from ~ 200...
