Fig. 3: Seismic reflection profiles show how the pockmarks relate geometrically to the faults and the effect of erosion on the pockmark base.
From: Evidence of pockmarks and seafloor gas venting in the northwestern Arabian Sea
a A seismic profile illustrates the seismic disturbances (SD) or acoustic turbidity (that indicate fracture conduits), seafloor pockmarks, and fault conduits (black dashed line). b, c seismic profiles show several bright spots (BS), with insets 1 and 2 representing bathymetric profiles that show seafloor pockmarks across the same profiles. d Seismic profile shows the same features as b, c, in addition to inset 3, which illustrates the vertical displacement of the seafloor. e Inset 4 shows polarity reversal (PR). f, g Show several faults and fracture conduits below seafloor pockmarks, with inset 5 illustrating the erosional truncation of the seismic reflections by the seafloor.
