Abstract(Summary)
The combined multichannel seismic and OBS data will allow detailed velocity analyses to investigate the permafrost signature and help mapping zones of high-velocity sediments indicative of the presence of ice along the four main lines crossing the OBS stations in the Transect 1 Area). Initial analysis of individual shot gathers show clear refraction arrivals with velocities around 2000 m/s (see Chapter 3 for more details) in areas of expected permafrost occurrence, and shot gathers lacked such arrivals in zones where the permafrost was predicted to be absent. It is therefore expected that the OBS data, once post-processed will also show clear refracted arrivals for velocity analyses.
