This sidescan record shows seafloor seep geology with several seeps.

We interpret the white blobs with black outlines at the upper right to be seeps. The strong reflection (black) represents the impedence contrast between sea water and the seep gas.

Exposed bedding on the seafloor, at the lower left, is cross-cut by a fault.

Such bedding is typical of eroded fold structures. The local seeps are distributed along the fractured crests of anticlines.
