I she is in fresh water she would be at 102 feet because fresh water is less dense than salt water.

Also at the surface, the diver is under 1 atm of pressure (from the atmosphere acting on the diver). 1atm + (depth / 33) = 4 depth / 33 = 4 - 1 depth / 33 = 3 depth = 3 * 33 depth = 99 feet<br><b>References : </b><br> Every 33 feet (10m) of salt water is another atm of pressure.
Also at the surface, the diver is under 1 atm of pressure (from the atmosphere acting on the diver).

1atm + (depth / 33) = 4
depth / 33 = 4 – 1
depth / 33 = 3
depth = 3 * 33
depth = 99 feet
