Zachariadis, R G

A method for seismic exploration at a marine exploration site, is described which consists of the steps of: a. fixing a seismic energy source and a seismic energy detector on the water bottom at a point offset from a marine exploration line, b. traversing the marine vessel towing a seismic energy source and a seismic marine cable employing a plurality of spaced-apart hydrophones, c. generating seismic energy from the towed seismic energy source to produce a seismic reflection signal that is detected by the plurality of hydrophones on the seismic marine cable and a first seismic refraction signal that is detected by the fixed seismic energy detector, the first seismic refraction signal including a source statics attributable to time delay in the near surface earth formation directly below the towed seismic energy source, d. generating seismic energy from the fixed seismic energy source to produce a second seismic refraction signal that is detected by each of the plurality of hydrophones on the seismic marine cable, the second seismic refraction signal including a receiver statics attributable to time delay in the near surface earth formation directly below each of the pluarlity of hydrophones.
