This seismic survey of the Juan de Fuca Plate has the specific aim of characterizing the plate from its formation at the ridge, through alteration and hydration of the plate as it ages, to subduction of the plate along the Cascadia margin. Owing to the very high risk of large earthquakes in Cascadia, improved understanding of the role of water in the subduction process is a primary broader impact of the survey. The project is also an important adjunct to the Cascadia Initiative, a multi-year deployment of instruments both onshore and offshore to study the structure and seismicity of the Cascadia region.

This data set was acquired with instruments from the Ocean Bottom Seismograph Instrument Pool (http://www.obsip.org) during the 2012 expeditions R/V Oceanus OC1206A (Chief Scientist: Dr. J. Pablo Canales) and R/V Marcus G. Langseth MGL1211 (Chief Scientist: Dr. Suzanne Carbotte). These data files are of SEG-Y format and include wide-angle reflection/refraction seismic data. Data were acquired as part of the project: Collaborative Research: Evolution and hydration of the Juan de Fuca crust and uppermost mantle: A plate-scale seismic investigation from ridge to trench, and funding was provided by NSF grants OCE10-29305 and OCE10-29411.
