【摘要】：为了解南大洋水团的分布特征并进一步为渔业生产提供信息参考,本文采用雪龙号第29次南极考察CTD数据,通过定性综合分析法、浓度混合分析法以及聚类分析法对2013年夏季普里兹湾水团进行了分析。研究结果表明,2013年夏季普里兹湾共存在6个水团,分别为夏季表层水、冬季陆架混合水、夏季冬季混合水、冰架水、绕极深层水和南极底层水。其中夏季表层水位于普里兹湾东北海域,只占薄薄的一层;冰架水向北可延伸至66°48′S;绕极深层水以及南极底层水在大陆坡处都存在显著的爬升,水体的爬升带动营养盐上升,在水深200~600m处与其他水团扰动混合,容易形成渔场。
[Abstract]:In order to understand the distribution characteristics of water masses in the Southern Ocean and to provide further information for fishery production, the CTD data of Xue long's 29th Antarctic investigation were used in this paper, and the qualitative comprehensive analysis method was used. Concentration mixing analysis and cluster analysis were used to analyze the Prydz Bay water mass in summer 2013. The results show that there are six water masses in Prydz Bay in the summer of 2013, namely, surface water in summer, mixed water in continental shelf in winter, mixed water in summer and winter, ice shelf water, deep water around the pole and bottom water in Antarctica. In summer, the surface water is located in the northeast sea area of Prydz Bay, occupying only a thin layer; the ice shelf water extends northward to 66 掳48s; the deep water around the pole and the bottom water of the South Pole all have significant climbs on the continental slope, and the climbing of the water body leads to the rise of nutrients. It is easy to form fishing ground by mixing with other water masses at a depth of 200 ~ 600m.
