Information to be Derived: seismic imagery
Summary of Activity and Data Gathered: Sparker multichannel seismic and CHIRP subbottom data were acquired along the Cascadia submarine forearc offshore Oregon and Washington on R/V Rachel Carson. The lines extended from nearshore to the deformation front and were spaced every ~25-50 km. Seismic systems were owned and operated by USGS. This work occurred on R/V Carson cruises RC0028 and RC0029.
