To substantiate the calmness of the mud bank

(1) According to W. King (1881) attribute to the presence of oil along with mud which causes damping of the waves

(2) Keen and Russle attribute the calming effect to the mud itself – i.e. mud is suspension increases viscosity of water and causes damping of waves. This is also referred as liquid mud.

Generally, the mud colour is dark green and contains some forameniferan remains. The fineness of mud gives it an oily feeling consisting of 3/4^th clay (<2µm or <0.002 mm) and 1/4^th of silt (2µm to 20µm or 0.002 mm to 0.02 mm). The rich phosphate content of the mud was observed by Jayaraman and Sheshappa.
