Pre-stack depth migrated multi-channel seismic images and velocity models of the sediment section near the Cascadia deformation front off Oregon and Washington, acquired during the R/V Marcus G. Langseth survey MGL1211 (2012)

This dataset contains the pre-stack depth-migrated MCS data along two transects across the Cascadia deformation front, offshore central Oregon near 44.6?N and Washington near 47.4?N acquired during the 2012 R/V Langseth survey. The seismic reflection images and seismic velocity of the two transects reveal contrasting deformation styles and consolidation states of the sediment section offshore central Oregon and Washington. Funded by NSF grants OCE10-29411 and 1457221.
