Estimates the potential temperature of seawater, using the UNESCO 1983 polynomial.
It is the temperature an element of seawater would have if raised adiabatically with no change of salinity, to atmospheric pressure.

t |
temperature, degrees C, |
S |
practical salinity, -, |
p |
gauge or applied pressure, pressure referenced against the local atmospheric pressure, bar |
pref |
reference hydrostatic pressure, bar. |
Temperature, degrees C.
sw_tpot
for S = 40, t = 40, p = 1000 is 36.89073 dgC
