2D seismicAs a young guy my first job (1976) was working working on a seismic crew (Petty Ray Geophysical) in the foothills of Alberta. We either used Dynomite or Vibrosise trucks with Jugs as we called them to collect the data.. Computer took up the whole back of a 5 tonne truck
Im pleased to see the meathod to create the seimic shocks to be picked up has greatly mproved the impact to the environment. They will be only staying on existing roads
Here is a video of the neat compact unit they use.
