1 ATM is actually equal to mean sea level itself. Now if you filled a balloon with air and put it under the water, you would notice that the volume will decrease. This decrement will increase as you go further down. Since the volume is decreasing, pressure must be building up inside (PV=nRT), assuming that the temperature doesn't change. Thus undersea pressure will be higher than 1 ATM.
Addition
For water pressure alone, 10 meters of water is equivalent to 1 atmosphere of air pressure.

How many meters underwater is one ATM?
Around 10 meters.
How do you calculate the pressure acting on an organism below the ocean's surface?
add 1 atm (atmosphere) for every 10 meters below the surface
Is 2 ATM the water pressure at 20 meters?
3 ATM at 20 meters.
What is the expected pressure of air in lungs of a diver at 4 meters below the sea level?
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.)
Why is the pressure at 14000 ft above sea level 0.69 ATM while the pressure at 14000 ft below sea level is 470 ATM?
The pressure of rarefied air is strongly different from the pressure of a big layer of water.
3 ATM equals how many meters?
Atmosphere is a measure of pressure, not of length like the meter.
What is the average air pressure in a hole 500 meters below sea level?
795.0
What level is excl in RuneScape?
I'm level 110 atm.
The deepest point in the ocean is 11km below sea level deeper than Mt Everest is tall What is the pressure in atmospheres at this depth?
1100 atm
10 ATM or 100 meters on a watch?
HI sir 10 ATM is 100M so it's the same thing..
What affects water pressure?
For any body of water near sea level, the pressure increases by 1 ATM per 33 feet below the surface.
1 atm is equal to?
The average value, at sea level, is 101,325 pascals.
