摘      要：At present,it is believed that the freezing point temperature of seawater is a function of salinity and pressure,and the freezing point is a key parameter in a coupled air-sea-ice ***,empirical formulas or methods are used to calculate the freezing point of *** in high-pressure situations,e.g.,under a thick ice sheet or ice shelf,the pressure term must be taken into account in the determination of seawater freezing point *** study summarized various methods that have been used to calculate seawater freezing point with high *** methods that were employed in two ocean-ice models were also *** identified the disadvantages of these methods used in these two models and addressed the corresponding uncertainties of the freezing point temperature *** study provides useful information on the calculation of the freezing point temperature in numerical modeling and indicates a need to investigate the sensitivity of numerical simulations to the uncertainties in the freezing point temperature in future.
