摘要：

介绍了海洋学计算中3 种深度与压强的转化方法:(1)EOS-80(Equation of State of Seawater 1980,EOS-80)标准采用的方法;(2)最新发布的TEOS-10(Thermodynamics Equation of seawater 2010,TEOS-10)标准采用的方法;(3)通过海水吉布斯函数计算压强与深度的关系的方法。对以上3 种计算方法进行了比较,结果表明:在一般的海洋学研究中,3 种方法精度相差不大,均可使用。在要求计算效率的情况下,可以选用EOS-80 标准采用的方法,在更高精度的海洋学研究中,应该使用TEOS-10标准采用的方法或者吉布斯函数方法。

Three conversion methods of depth and pressure in the ocean are described. (1) Method adopted by EOS-80 standard (Equation of State of Seawater 1980, EOS-80); (2) Method adopted by TEOS-10 standard (Thermodynamics Equation of seawater 2010,TEOS-10); (3) Convert pressure to depth via the Gibbs function of seawater. After comparison of three methods, the results show that, in general oceanographic research, the three methods can all be used in general oceanographic research, according to their similar accuracy. However, the EOS-80 method should be adopted in the request of computational efficiency, and the TEOS-10 method or Gibbs function method should be taken in the high-precision oceanographic research.
