However, atmospheric changes are trivial in comparison to simply swimming from say 4' to 5' depth.
Atmospheric pressure is double at a water depth of 34ft compared to what it is at the surface. There is more of a pressure change going from a depth of 4ft to 7ft than you would see from the pressure change of an approaching hurricane. Fish go through these pressure changes in depth all the time with little or no consequence. Now when you bring fish up from real deep water, some can have real problems with the extreme change in pressure changes being exerted by the water depth. At a depth of 100ft the pressure is 3 times what it is on the surface. At sea level the air pressure is 14.7 psi.
Anyone else ever take scuba diving lessons?
