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.

Source was Bolt 1500LL and 1900LL.;This set of acquisition parameters was used for the 2-D MCS sequences 030-041.;Source volume for sequences 020, 023, 024, 031 and 032 was affected by maintenance of the sub-arrays (airgun strings) during shooting and was changed between half volume (3300 cu.in.), three-quarters volume (4950 cu.in.) and full volume (6600 cu.in.) reflecting the use of 2, 3 or 4 airgun string sub-arrays per source - see SEAL 408 Line Configuration By Sequence document and individual sequence logs for details.;The shot spacing for sequences 020, 023, 024, 031 and 032 was 150m due to the airgun maintenance periods, and was 50m for all other MCS sequences.
