are adequate. In the equation above, ρ 0 , T 0 and S 0 are a reference density, a reference salinity and a reference temperature. The two expansion coefficients α T
and α S are both positive as the density increases with both decreasing temperature
and increasing salinity. Several typical properties of seawater are summarized in
Table 1.9. Nonlinearities in the equation of state can, however, lead to interesting
phenomena such as cabelling (where the two water masses mix and the resulting
water mass is heavier that each of them) and thermobaricity (the thermal expansion coefficient increases with depth).
