The total pressure on a diver under water is the result of two separate forces which act simultaneously upon him. These are: the weight of the water and the weight of the atmosphere over the surface of the water. For fellow divers; what is the total number of atmospheres of pressure on a scuba diver standing zero buoyancy within 30 meters of water? Trivia for divers!

Not really trivia, but a good question that every diver should know.
(Depth/33)+1=ATA
(99/3)+1=4 ATA
(Depth/33)+1=ATA
(99/3)+1=4 ATA

Correct. Approximately every 10 meters of water adds an additional 1 atmoshere of pressure to the diver, at 30 meters, there are 4 atmospheres pressure on the diver, including the 1 atmosphere from the atmosphere pressure on the water, and 3 atmosheres pressure of the weight of the water. Thus a total of 4 atmospheres pressure at 30 meters depth.

Divide by 33 as every 33' you descend adds one, don't forget one at the surface...so 99/33 + 1...

4 ata. 1 atmosphere for every 33ft plus the 1 atmosphere you have from the weight of the air at sea level. I knew this off the top of my head but here is a good cheat sheet

This is a basic question for anyone who enjoys SCUBA diving, or at least it is something you very well should know. Knowing your depth and bottom time is something that every diver should know and understand or else you'll find yourself in a very bad situation.
