Seismic Diffraction Analysis of a Fluid Escape Pipe beneath the Submarine Gas Bubble Plume in the Haima Cold Seep Area

Figure 6

Diffractions on the different shot gathers. (a) Shot gather without clear diffraction; (b, c) show some short-spread diffractions; (d) diffractions with strong amplitude on shot 1780; (e, f) show gathers with three diffraction waves. As the shot number increases, diffraction occurs at later times; (f, g) show low-amplitude diffractions.
