摘　　要：首先描述了Del Grosso算法和C.C.Leroy算法计算海洋声速及其特点(貌似不通);然后利用美国国家海洋数据中心发布的WOA09数据,分别采用Del Grosso算法和C.C.Leroy算法计算西太平洋海域某点的海洋声速剖面,结果表明两种算法具有相同的个位数字精度。与Del Grosso算法相比,C.C.Leroy算法效率更高,不需要深度与压强的转换。This paper, describes Del Grosso and C C Leroy algorithms for calculating SSP and their characteristics.With the WOA09 data from the US National Oceanographic Data Center, the ocean sound speed profile located at the region of west Pacific Ocean is calculated using Del Grosso algorithm and C C Leroy algorithm respectively.The results show that both Del Grosso algorithm and C C Leroy algorithm have the same accuracy at the sigle digit. Moreover, C C Leroy algorithm has higher computation efficiency than Del Grosso algorithm, which doesn＇ t need the transform of depth and pressure.
