Processed pre-stack depth-migrated seismic reflection data from the 2021 CASIE21 multi-channel seismic survey (MGL2104)

This data set presents processed Multi-Channel Seismic (MCS) reflection data acquired during the CASIE21: Cascadia Seismic Imaging Experiment 2021. In the CASIE21 marine seismic experiment a series of 18 primary margin crossing lines and 6 margin parallel lines were acquired spanning the offshore Cascadia subduction zone from ~42° to 50°N during R/V Marcus Langseth cruise MGL2104. The files in this data set are pre-stack depth-migrated reflections stacks with advanced processing routines applied. Details of the processing work flow are described in the linked data processing document. The data files are in SEG-Y format. Funding was provided through NSF grants OCE 1827452, 1829113, 1827363.
