1978年新实用盐标和1980年新国际海水状态方程为海洋学者重新审定海水现有己知的物理性质提供了方便,这些物理性质是大洋作为动力系统和热力系统所必不可少的。 JPOTS得到了测量CTD的SCOR工作组(WG—51)所推荐的演算方法,这些演算法包括由电导率比转换成新实用盐标、海水的比容、以新状态方程为基础的比容偏差、比热、绝热递减率、位温和声速。 The new 1978 practical salt standard and the new 1980 State of the Sea State equation for ocean water provide the convenience for oceanographers in revalidating existing physical properties of seawater that are essential to the oceans as a dynamic and thermodynamic system. JPOTS has been recommended by the SCOR Working Group on the Measurement of CTD (WG-51) for the proposed methods of calculation, including conversion from conductivity ratio to a new practical salt standard, specific volume of seawater, specific volume deviation based on the new state equation , Specific heat, adiabatic decline rate, bit gentle sound velocity.
