before the total pressure you feel is triple that of atmospheric pressure at sea level (itself about 100,000 Pa)*?

Hi. In sea water the first atmospheric pressure doubling is at about 30 feet. Next atmospheric increment is at about 60 feet. Check the web to verify. (This is from a NAUI course I took years ago.)

A pascal is a newton per square meter and a newton is 1 kg time g, so triple the atmospheric pressure is 300,000 kg*g/m^2 and the mass equivalent is 300,000 kg/m^2
Water's density is 1000 kg/m^3, so the columnar height to get 3 atmospheres can be gotten by dividing the desired mass equivalent by the density of the water.
