Laboratory-measured transit times of P- and S-waves, manually picked to determine compressional and shear wave velocities. (a) travel-time picking for the P-wave (1 MHz) and (b) travel-time picking for the S-wave (500 kHz). An example of manually calculating the arrival times of the P and S waves, in microseconds, in order to calculate the velocities in the samples, which were measured in the laboratory using transducers.
