MGL1902_ACQ001 (Lines: Sequences 001, 002, and 007 - all OBS only.)

Source Information

AirGun (BOLT:1500LL)

Source Number: 36

Volume (cu in): 6600

Pressure (psi): 2000

Depth (m): 12

Shot Interval (m): 300

Distance to Antenna (m): 230

Number of Arrays: 1

Receiver Information

Seismic:OBS

Used Active Tail Buoy: false

Used Compass Birds: false

Nav System

C-Nav 3050 primary

WGS84

Acquisition System

Digital

Name: OBS

Details

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 sequence 007, the shot spacing interval was 400m.
