| 摘 要： | 选取联系南海与台湾海峡 及巴士海峡的主要海上交通和军事要道－我国台湾省恒春西南海域作为研究海域,依据1998年夏,冬季对本海域海洋环境补充调查的CTD资料,按《海洋调查资料处理》的声速换算经验公式,推算得到本海域的海水声速系列,结合该海域温,盐环境背景,分析其声速场特性,给出海水声速的平面,垂及断面分布,也给出了本海域海水声速跃层深度,厚度和强度等三大表征值的变化特性及其声道位置。

| Abstract: | The research area is the southwest sea area off Hengchun, Taiwan Island. It is the main transport and military channel linking the South China Sea, Taiwan Strait and Bass Strait. Based on the sound velocity conversion formula in "The Treatment of Ocean Investigation Information"(GB 12763.7-91), CTD data in the adding investigation of ocean environment during summer and winter of 1998,under project, are used to calculate the sound velocity series. Combinad with the characteristics of sound velocity field and the temperature and salinity environment of the area, the horizontal, vertical and sectional distributions of sound velocity, the three main characteristic value,e.g. depth, thickness, strength and the variation of sound velocity isocline , as well as the location of sound channel are given out. |
