| 摘 要： | 根据我国首次北极科学考察所获 CTD资料 ,分析了白令海和楚科奇海的水文特征和水团结构。研究表明 :(1 )该两海域温、盐度的分布有着明显的区域性差异。楚科奇海的温、盐度普遍低于白令海。 (2 )夏季 ,白令海大部分水域温度垂直分布的突出特点是 :在 2 0 m和 2 5 0 m间存在温度低于 3°C的中层冷水。 (3 )在楚科奇海北纬 70°以北海域 ,不论是水温或盐度皆明显减小 ,从而在此区域形成强的温、盐度锋带。 (4)在白令海存在三种水团 ,而楚科奇海的水团则大致分为两类

| Abstract: | The hydrographic feature and water masses in the Bering Sea and the Chukchi Sea are analyzed on the basis of the observations of the first Chinese National Arctic Research Expedition. The results show that:(1)The distribution of temperature and salinity present obvious regional difference in both the Bering Sea and the Chukchi Sea. (2)The Intermediate Cold Water, which is the main feature of the temperature vertical structure, occurred in the depth between 20 and 250m in the most areas of the Bering Sea in summer.(3)Both the temperature and the salinity decrease obviously in the sea areas north of 70°N, where a thermobaline front is formed.(4)There are three and two kinds of different water masses in the Bering Sea and the Chukchi Sea respectively. |
