Analysis of the Characteristics of the Sound Velocity Profile in the Arctic Region Based on WOA18 Data

论文基于WOA18海洋数据,分析了北极地区声速剖面特征。结果表明:北极地区的夏季声速高、冬季声速低;高纬度地区的表层声速低、低纬度地区的表层声速高;高纬度地区的声速最大值在表层,低纬度地区声速最小值对应的深度呈现出夏季深、冬季浅的特征等。

Based on the WOA18 data,this paper analyzes the characteristics of the sound velocity profile in the Arctic region.The results show that the sound speed in the arctic region is high in summer and low in winter.The surface sound velocity is low in high latitude areas and high in low latitude ares.The maximum sound speed in high latitudes is at the surface,and the depth corre⁃sponding to the minimum sound speed in low latitudes is deep in summer and shallow in winter,etc.
