Pressure at any point inside a fluid, in addition to the atmospheric pressure at its surface, is given by:
P=hdg (where, h is the depth of the point from the surface, d, the density of the fluid and g, acceleration due to gravity).
A deep ocean, by definition, has a minimum depth of 5490 meters.
Assuming g remains constant at this depth and plugging in the values,
`= 54934038` Pascals
`=54934038/101325` atm (since 1 atm = 101325 Pa)
Considering the atmospheric pressure (1 atmosphere at the sea surface), total pressure at this depth of ocean will be =(542.2+1) =543.2 atm.
Thus, the minimum pressure at the basin of a deep ocean is 543.2 atmospheres.
