Meade-1 is approximately 1.2km long. Receiver sensors are 28Hz vertical component and spacing is 5m. Seismic source is 3 gasoline powered earth tampers operated in random fashion and spacing is 5m. The line progressed from west to east with the source in an “off end” configuration on the west end. Field files are correlated. Meade-2 is approximately 700m long. Receiver sensors are 28Hz vertical component and spacing is 2.5m. Source is a 12 gauge shotgun using black powder blanks and spacing is 2.5m.
