Abstract:

The raw 2D multichannel seismic reflection data in this project were acquired during
expedition SO294 offshore Vancouver Island, Canada, using two different sources, i.e., a single
GI Gun and a GGun array. The data were recorded with an 184-channel streamer. The
objectives of expedition SO294 were twofold: provision of geophysical images to constrain the
hazard potential of the Cascadia subduction zone, and to constrain the geophysical properties
of the oceanic crust to assess its storage potential for carbon capture and storage (CCS). The
data comprise 1660 line kilometers and are provided in raw format (SEG-D) and associated
standardized metadata. Detailed information on the acquisition can be found in the SO294
cruise report (https://doi.org/10.48433/cr_so294). In addition, this technical report is provided
with the 2D multichannel seismic reflection data set.
