Gravity at every point on the surface of the earth varies slightly depending on: distance from the equator; density of the underlying rocks. Original aim of the refraction survey has been to locate the bedrock surface, and to define seismic velocities in overburden and in bedrock. A modern seismic acquisition system uses several navigation systems firstly to determine and control the position of the vessel in the water and secondly to determine the position of the seismic equipment trailing the vessel. The results, in conjunction with field mapping and other information such as seismic or borehole data, can then be used to assess the most favorable areas within the region for further investigation. The main types of seismic waves: P, S, and surface waves Seismic waves can either be body waves or surface waves -- but the full story is far more complex.

Seismic Pros Consultants is a group of skilled and experienced people with many years in the seismic industry. Based on a typical propagation mechanism used in a seismic survey, seismic waves are grouped primarily into direct,. Alan Bailey. A seismic trace represents the response of the elastic wavefield to velocity and density contrasts across interfaces of layers of rock or sediments as energy travels from a source through the subsurface to a receiver or receiver array. ELECTRICAL RESISTIVITY METHOD The electrical resistivity method involves the measurement of the apparent resistivity of soils and rock as a function of depth or position. Of all the geophysical exploration methods, seismic surveying is unequivocally the most important, primarily because it is capable of detecting large-scale to small-scale subsurface features. Well and test hole information is important in determining the thickness of surficial deposits and mapping the extent of older deposits covered by younger materials.
