Geophysical Indicators of Gas Hydrate in the Northern Continental Margin, South China Sea
Figure 4
CMP gather shows how interval velocities were obtained. (a) Normal-moveout-corrected CMP gather shown in Figure 3(a). (b) shows the semblance plot and the interval velocity calculated from the Dix equation for the crosses locations. Higher interval velocity is shown in the layer of 1.85–1.95 s.
