Source was Bolt 1500LL and 1900LL. This set of acquisition parameters was used for airgun shooting to OBS instruments. No streamer was used so there are no cables or channels.; For sequences 001, 011, 012, 018, the source volume was 3300 cubic inches (i.e. half the full volume).; For sequences 002, 009, 010, 013, 019 the source volume was changed between full volume (6600 cu.in.) and half volume (3300 cu.in.) - see individual sequence logs for details.; Sequences 003-008 and 014-016 were at full volume.; The number of sub-arrays per source was 4 for shooting at full volume, 2 for half volume.; The shot spacing for sequences 001-015 and 018 was 150m, and was 250m for sequences 016, 017 and 019.
