yes, rarely, but yes. When you go diving and loose something and that screws the dive, and a good day at work is when you receive a raise....and you can think about your next dive trip....!
What's the worst dive you ever had?
What's the worst dive you ever had?
First dive in Chile. Gas powered compressor that leaked exhaust fumes into the fill. Air tated like diesel exhaust and after 15 minutes I had a terrible headache. But had to finish the job (counting species in a kelp holdfasts) so I had to surface after every couple minutes (after every holdfast) for fresh air to make the headache go away and go back for another holdfast.

What's this I hear about the dry adiabatic lapse rate?
What's this I hear about the dry adiabatic lapse rate?
50psi?!:
The adiabatic lapse rate is the rate of temperature change that occurs in an atmosphere as a function of elevation, assuming that air behaves adiabatically (thermally insulated). This term is most commonly used to refer to Earth's atmosphere.
The relationship between change in altitude and change in temperature is expressed as a lapse rate. In general, a lapse rate is the rate at which an atmospheric variable (usually temperature) decreases with altitude. It is expressed as the negative ratio of the temperature change and the altitude change, thus:
where γ = lapse rate is given in units of temperature divided by units of altitude, T = temperature, and z = altitude, and points 1 and 2 are measurements at two different altitudes.
