Seismic cable LGT3622 is used to connect all the geophones which record the seismic waves resulting from either Vibroseis or dynamite when recording seismic data. 

This is basically setting off a sound wave and then recording the time and path it takes to bounce off the rock layers (strata) below. A great number of these "seismic events" can be used to map the strata and structures deep underground to detect faults, oil and gas accumulations, salt domes, etc.
