Aeromagnetic interpretation and rock magnetism
By C.V. ReevesInterpretation of the vast body of aeromagnetic survey data which now exists (and which continues to grow al a rate of same 2500 000 line-km per year worldwide) is a complex discipline, particularly where attempts are made to integrale and reconcile the interpretation of a magnetic anomaly map with other sources of map data such as gravity surveys, gamma-ray spectrometer surveys. satellite imagery. photageology. geochemical surveys and outcrop information (Reeves 1985. Paterson and Reeves 1985).

Streamer noise reduction with manufacturing techniques
Authors B.F. Giles and D.R. SteeteResults of marine geophysical tests show that a highamplitude low-frequency noise wave is propagated through the cable from section to section at a relatively high velocity but is propagated within each section at a relatively low veIocity . This noise wave has been generally referred to as the 'bulge wave' or 'cable jerk'. Results of early tests reveal characteristics about the bulge wave that can be utilized in the streamer design to effectively attenuate this noise.

Prestack migration by shot record inversion and common depth point stacking: a case study
Authors A. van der Schoot, R. Romijn, D.E. Larson and A.J. BerkhoutIn this paper a method for depth migration of individual shot records followed by common depth point (CDP) stacking is described and iIIustrated with a real data example. First we explain the philosophy behind shot record migration. Then we go through the different stages of the procedure using a real data example.
