Seismic Structure of the Ocean Continent Boundary in the Newfoundland Basin from a Multichannel Seismic Line
Detailed wide angle Ocean Bottom Seismometer and vertical incidence multichannel seismic (MCS) data were collected along three main transects across the Newfoundland Shelf as part of the Study of Continental Rifting and Extension on the Eastern Canadian sHelf (SCREECH). Extending from continental to...
