AbstractDuring expedition ARA08C, 890 km of multichannel seismic data have been collected offshore Yukon and Northwest Territories in water depths ranging from 23 to 1866 m onboard RV Araon operated by the Korea Polar Research Institute. The layout of the seismic program was designed to address a wide variety of geological problems including subsea permafrost, gas hydrates, glacial history, fluid migration and offshore geohazards. The survey provided a very high quality dataset but shallow water depths and hard sea bottom made the processing of the seismic data challenging. This report highlights processing methods applied on the dataset and briefly discusses processing results in terms of improvement of the subsurface imaging.
