f Field testing of a seismic G.I. gun array

During the last decades the airguns have become a standard energy source for seismic surveys in the industry. Sleeve guns were introduced a number of years ago and are widely used today. This paper aims at comparing the results of a testline shot with a sleeve gun array to the results of a testline shot with the newly developed G.I. gun array . These data were shot in the summer of 1991 . The data were acquired in Norwegian waters in quadrant 16. An airgun shot line from the same area, acquired in 1989, is also available for comparison .
