... with the method of Taner et al. (1998). That method assumes that the solution for the delay times at each station can be divided into a long-wavelength component resulting from the topography of the refractor, and a short-wavelength component due to variations in the seismic velocity and thickness of...

... of the P-wave component. The next step in obtaining a static solution is to use the traveltimes observed from the shear refractions to determine a model of the near-surface. There are several options available to accomplish this, including the slope/intercept method (Gardner, 1939, 1967), delay-time...

... interfaces (Barry, 1967; Palmer, 1986, Lankston, 1989). Most techniques used for interpreting refraction traveltimc-distance curves are derived from the concept of delay time. The re- fraction stack discussed here is also designed to utilize the de- lay times. These are combined using multifold data in which...

... that in marine seismic surveys time should be measured from the first implosion rather than from the time of explosion. This latter suggestion appears to be the most reasonable interpretation of the phenomenon since the charge size increases with distance with an attendant increase in the time period...

... the ability to incorporate S-wave with P- wave data analysis. Where the S-wave application is un- successful, these barriers often combine to limit signal-to- noise ratio (S/N), image resolution or detection sensitivity. Producing quality S-wave results typically requires greater expense (money, time...
