Abstract:: The global mid-ocean ridge system is the largest magmatic system encompassing over 75% of the Earth’s total volcanism. As magmas ascend through the vertically variable oceanic crust, melts begin to crystallize and diversify and subsequently erupt at the surface. The interpretation of these erupted products observed on the seafloor requires...

Abstract:: Passive hydrophone technologies and a variety of acoustic methods are applied in the deep-ocean and shallow water coastal environments of the northeast Pacific. A catalog derived from U.S. Navy regional hydrophone array recordings of acoustic T- phases from seafloor earthquakes is examined, describing space/time patterns through empirical orthogonal function analysis...
