利用中国第 1 5次南极科学考察科学考察队的CTD全深度观测资料 ( 1 998年1 1月至 1 999年 2月 ) ,分析并讨论了普里兹湾以北的南大洋海域内 ,绕极深层水(CDW )和南极底层水 (AABW )的物理特性及其空间分布 .同时还与历史上其他学者的发现进行了比较 .指出了在研究海域内 ,CDW在 1 0 0～ 2 0 0 0m之间从北向南扩展 ,其高温核 (t>1 2℃ )和高盐核 (S >34 7)在 75°E断面上最为深厚 ,向南扩展得最远 ;而AABW则在 2 50 0m以深由陆坡底部向北扩展 ,σθ>2 7 875的高密度水体在 70°E断面上最为深厚 ,向北扩展得最远 .此外还通过实测的CTD资料证实了CDW和AABW的经向环流特征 ,以及它们与迪肯流环 (Deaconcell)、亚极地流环和深层流环的一致性 .
Based on the CTD data from January to January 1999 to February 1999 from the 15th Scientific Expedition Team of Antarctic Expeditions in China, it is analyzed and discussed that in the South Pacific Ocean north of Prydz Bay, The physical properties and spatial distribution of very deep water (CDW) and Antarctic bottom water (AABW) are also compared with those of other scholars in history.It is pointed out that in the study area, the CDW is between 100 and 200 (T> 12 ℃) and high-salt nuclei (S> 34 7) are the deepest in the 75 ° E section and extend farther to the south, while the AABW is in the range of 2 50 0m depth extends northward from the bottom of the slope, and the high-density water body with σθ> 27 875 is the deepest at 70 ° E and farthest northward, and the meridional circulation of CDW and AABW is confirmed by the measured CTD data Features, and their consistency with Deaconcells, sub-polar currents, and deep currents.
