The “thermobaric barrier” calculation:
- Calculate the actual density (pressure included), subtract density of a water column with mixed layer properties. Determine the level (zmax) of the maximum difference: drmax.
- Determine the sensible heat that must be vented to reduce water temperature above zmax to ?ml.
- Add the latent heat loss required to increase salinity (by freezing) enough to eliminate ?? at zml
- Htot is the total heat loss.
