Source was Bolt 1500LL and 1900LL.;This set of acquisition parameters was used for airgun shooting to OBS instruments only. No streamer was used so there are no cables or channels. The shot spacing for Sequence 001 is 400m, for Sequences 003, 004 and 008 it is 250m, for Sequences 007, 013, 015 and 018 it is 50m. For all other OBS-only sequences it is 300m.

Source was Bolt 1500LL and 1900LL.;This set of acquisition parameters was used for MCS/OBS Sequences 048-057. For the 6000 meter-long streamer, the first 600 meters of the streamer were 96 high-resolution sections with channel spacing at 6.25 meters, and the remaining 5400 meters had 432 channels with a channel spacing at 12.5 meters.
