Seismic first breaks for Syczyn seismic survey

The dataset contains condensed results of seismic refraction survey, that can be regarded as “hard data”. Data files Syczyn-1_P.ASC and Syczyn-1_S.ASC represents tables obtained for line Syczyn-1, wave P and wave S respectively; Data files Syczyn-2_P.ASC and Syczyn-2_S.ASC represents tables obtained for line Syczyn-1, wave P and wave S respectively. Each file contains 4 columns: Record No. – sequential record identifier; Source location – distance from the beginning of the line to the (current) source point (in meters); Receiver location – distance from the beginning of the line to the given receiver (in meters); First Break – delay time between emission of the wave to its arrival at the given receiver point (seconds). Dataset is formatted in simple table, that can be imported to other seismic software for modelling velocity field. Different computing algorithms generate slightly different velocity models, so it can be useful to have hard data for comparison.

Statement: Raw seismic data acquired in field was analysed for occurrences of refracted waves. Time delay of refraction wave traveling to each of the seismic sensors (geophones) used in the survey for numerous source points allow for spatial sampling of the wave field of the refracted wave, and build model of seismic velocity cross section. Field seismic data were collected using precisely planned survey procedure. Field data were sorted, assembled and visually presented in a seismic processing software. Identification of the refracted waves were performed visually using the tendency of refracted waves to be the first waves to arrive. Time delay values were picked then manually. The results arranged in ASCII table were then exported. Model of the velocity field (seismic velocity cross-section) was computed on the basis of this tables for two lines and P (primary) and S (shear) waves for each line.
