Pressure at a given depth of water can be calculated using a formula like, "#1 #1kgf/cm2." Therefore, water pressure at 2000 meters below sea level will be around 1.2 bar.
The pressure at 100 meters below the surface of sea water with a density of 1150kg is 145.96 psi.
Because it increases. As you descend in the sea each 10 meters of water above you weighs as much as the whole of Earth's atmosphere as experience at Sea Level. Thus at 10 meters depth in the sea you experience a pressure of 2 atmospheres. At 20 meters 3 atmospheres At 30 meters 4 atmospheres At 100 meters 11 atmospheres At 1000 meters 101 atmospheres.
the sunda shelf is a platform or extension of mainland Southeast Asia that lies around 100 meters beneath the surface of the sea. the sunda shelf is a platform or extension of mainland Southeast Asia that lies around 100 meters beneath the surface of the sea.

High water pressure.
Water pressure is caused by the weight of the water that is above it. At deeper levels there is more water above you. So there is more mass pressing on the water you are in. Pressure does not depend on the width, only on the depth. It is the same in a large basin as it is in an equally high pipe. On the surface there is also atmospheric pressure, because the atmosphere (the air) also has mass. This pressure must be added to the water pressure. It is roughly the same as 10 meters of water pressure. So, at 10 meters under water you have twice as much pressure than at the surface, at 20 meters three times as much, and so on. Seawater is heavier than freshwater, because there is salt in it. So the water pressure for every meter of depth in the sea is slightly higher than it is in a lake.
Pressure increases the deeper you sink beneath the surface of the sea. So 20 metres below the surface has more pressure than 10 metres above the surface.
Air pressure (at sea level) is about 1 bar; every 10 meters below the water surface, pressure increases by about 1 bar - that gives a total of 1 + 0.4 = 1.4 bar. (1 bar is about 1 atmosphere.)
The pressure at the bottom of the ocean can be determined by the formula P = dgh, where d = 1025 kg per cubic meter, g is the acceleration due to gravity and h is the depth of the water in meters. At the bottom of the Marianas Trench (11034 meters), the pressure would be 1.11 E5 kPa, or 1095 times normal air pressure at sea level.
