Application of Geophysical Methods and Equipment to Explore the Sea Bottom

Part of the NATO Conference Series book series (NATOCS, volume 5)


In marine seismic surveys the acoustic signal is starting and spreading in the water, reflected or refracted at discontinuities of the bottom and subbottom, and then returning into the water to the detecting sensors. The exploration for hydrocarbons usually requires deep penetration by application of low frequencies (between 5 and 150 Hz) and does not need detailed information about the sea bottom. Increased frequencies lead to higher resolution of structures but to decreased penetration. In that direction the advanced seismic methods and equipment can be developed to determine the interesting acoustic parameters of the sea bottom by continuous profiling.

This paper will give a summary of the seismic technique and references for practicable developments in respect to research of the sea bottom.
