Three-component OBS-data processing for lithology and fluid prediction in the mid-Norway margin, NE Atlantic
In 1992, acomprehensive three-component ocean bottom seismic survey was performed in the central and northern area of the Vøring Basin, offshore...

Regional and semi-regional modelling of wide-angle shear waves in OBS data from the Vøring Basin, N. Norway—a comparison
Shear wave refractions and wide-angle reflections recorded on densely spaced Ocean Bottom Seismometers (OBSs) in the Vøring Basin have been modelled...

Seismic Structure and Seismicity in the Southern Mariana Trough and Their Relation to Hydrothermal Activity
The Southern Mariana Trough is an active back-arc basin with hydrothermal activity. We investigated relations between the back-arc spreading system...

A first insight into the Marsili volcanic seamount (Tyrrhenian Sea, Italy): Results from ORION-GEOSTAR3 experiment
The Marsili Seamount is the largest European underwater volcano. It is Plio-Pleistocenic in age, rising up to more than 3000m from the seafloor in...
