Editing Gulf of Thailand (section)

===Seabed morphology===
The seabed morphology in the central depression of the gulf is characterised by the presence of elongated mounds and ridges arranged parallel to the axis of the [[Oceanic basin|basin]]. This morphology, widespread within the gulf in water depths exceeding 50 m, covers an area of tens of thousands of square kilometres.

It reflects an interaction between [[sediment]] dewatering and the [[Hydraulic action|erosional activity]] of the present-day [[Ocean current|bottom currents]].<ref name=Puchala/> The [[sediment]] dewatering and fluid seepage result in the formation of numerous small pits and [[Pockmark (geology)|pockmarks]]. The long-term [[Hydraulic action|erosion]] imposed by [[Ocean current|currents]] of stable orientation modifies [[Pockmark (geology)|pockmarks]] into long runnels and depressions, and ultimately leads to the formation of the large fields of elongated mounds and ridges, as well as the residual outliers of un-eroded mud and clay sheets.<ref name=Puchala>{{Citation |last1=Puchala |first1=R. |title=Morphology and origin of modern seabed features in the central basin of the Gulf of Thailand |date=2014 |doi=10.13140/RG.2.1.3891.0808}}</ref>
