Description:

Abstract: This dataset contains the time-migrated MCS data along two ridge-to-trench transects across the Juan de Fuca (JdF) plate, from Endeavour Ridge to offshore Washington state and from Axial Volcano to offshore Oregon state, and one 400 km-long trench-parallel transect extending from 44.3N to 47.8N acquired during the 2012 R/V Langseth survey. The seismic reflection images of the two ridge-to-trench transects reveal the crustal structure of the JdF plate, distribution and extent of faults across the plate interior as the crust ages and near the deformation front in response to subduction bending, and a series of distinctive, ridgeward-dipping (20-40 degrees) lower crustal reflections in ~6-8 Ma crust along both transects. The trench-parallel transect characterize the along-strike structural variations of the sediment section and the JdF plate prior to subduction, in particular the structures associated with propagator wakes, a seamount, and four major strike-slip faults. Funded by NSF grants OCE10-29411. http://dx.doi.org/10.1594/IEDA/500069
