a A slope gradient map derived from the multibeam bathymetry, showing the locations of b–d. The light blue circles represent the discovered gas seeps, the red dots refer to the circular pockmarks (CiPM), and the solid green and blue polygons refer to the crescent-shaped pockmarks (CrPM) and complex pockmark strings (PM strings), respectively. The dashed blue and red polygons represent areas containing most of the complex-shaped pockmarks and the simple circular pockmarks, respectively. b–d highlight the different pockmark geometries with inset 1–3 as bathymetric profiles across these pockmarks.
