Right at the surface of the ocean, the pressure is just the same as the air pressure at sea level; that is, one "atmosphere", or about 14.7 PSI (Pounds per Square Inch).
But water pressure increases with increasing depth: For each foot of depth, the water pressure increases by 0.445 PSI.
Scuba divers, who need to be very aware their depth because of this pressure effect, often use this rule: Every 33 feet of depth, water pressure increases by one "atmosphere" (14.7 PSI). So, for example, at 66 feet the pressure on a diver is three atmospheres: There's one atmosphere of pressure from the air, and two atmospheres from the water.

What is the difference between thermocline and halocline?
thermocline is the level in the ocean/sea water that dramatically DECREASES in temperature, and the halocline is the level in the ocean/sea water that dramatically INCREASES in temperature
Does water boil at a lower level above sea level?
First understand that the boiling of water occurs when the energy of water molecules is equal to the vapour pressure... (i.e energy of water is equal to the external pressure due to the atmosphere)... above sea level the atmospheric pressure is lower hence low energy is required... hence water boil at low temperature...
What is the pressure in bar at 400 meters sea depth?
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.
How does the pressure at a certain depth in sea water differ from that at the same depth in river water?
Since liquid pressure is function of density,acceleration due to gravity and depth of liquid level so here density of sea water is greater than that of river water ,so liquid pressure in sea must be more.
How do you think boiling of water will change on sea level as compared to boiling water on a mountain top?
I think that the temperature required to boil water is lower at high altitudes (where the atmospheric pressure is lower) than at sea level.
What has a higher vapor pressure water at sea level or the mountains?
water at sea level has higher vapor pressure
How and why do temperature and pressure vary with ocean depth?
At sea level,the pressure of the atmosphere pushing down on the ocean surface is reffered to as 1 atmosphere of pressure.An atmosphere is the pressure exerted on a surface at sea level by the column of air above it.As you go below the oceans surface ,the pressure increases because of the force of the water molecules pushing down.
Where is water pressure the least?
at sea level
Where is water pressure least?
at sea level
What is the difference between thermocline and halocline?
thermocline is the level in the ocean/sea water that dramatically DECREASES in temperature, and the halocline is the level in the ocean/sea water that dramatically INCREASES in temperature
What is the pressure of the bottom of the crust?
It depends where in the ocean you mean! To work this out: At sea level, the Earth's atmosphere exerts a pressure of 1 bar. Then each 10 meter depth of Sea Water also exerts a pressure of 1 bar. So take your ocean bottom depth (in meters) divide it by 10 and add 1. This will give you the pressure at that depth of ocean. alot
When the water of the ocean is at a higher level than its average this is referred to as .?
When the water of the ocean is at a higher level than its average, this is referred to as sea level rise.
What is the air pressure at sea level called?
Sea level pressure, sometimes as mean sea level pressure.
Is the ocean above at or below sea level?
The ocean is at sea level.
The lowest point in the state of Hawaii?
The lowest point in Hawaii is in the Pacific Ocean at sea level. what the heck!
What happens to sea level as a glacier melts?
As a glacier melts, the water runs into the ocean, causing sea level to go up.
Is the level of the water in the Atlantic Ocean and the Pacific Ocean different through the Panama Canal?
Yes it is different because if it goes to another ocean then the water level will drop. No, the previous posted answer is incorrect. Ocean water level is the same anywhere. Sea level on the Atlantic and Pacific Oceans are the same.
