利用中国第九次南大洋考察中南极普里兹湾及其邻近海域的ＣＴＤ资料，分析研究了调查海域的水文结构特征及其该区南极底层水（ＡＡＢＷ）的来源．研究结果表明，在研究海域，深水洋区近表层流由西向东流，而在普里兹湾内存在一个气旋型涡．水文结构中最明显的海洋学特征是：（１）绕极深层水（ＣＤＷ）的涌升现象明显，涌升最强的位置是麦克罗伯逊地以北海域，最明显的深度是５０～２００ｍ层，暖水涌升将冬季冷水分隔成南北两部分，并在其中形成孤立的暖水块；（２）陆缘水边界明显，这是绕极深层水与南极冷水之间形成的锋面，一般处在次表层水中，大致位于６４°～６６°Ｓ之间；（３）存在着双跃层结构．观测期间，普里兹湾以北探水海域存在着南极底层水，其来源可能有二：一为当地形成，二为源于威德尔海和罗斯海．
Based on the CTD data of the Prydz Bay and its adjacent waters in the South Pole from the 9th South Pacific Ocean in China, the hydrological structural characteristics of the surveyed sea area and the source of the AABW in this area were analyzed. The results show that in the study area, near-surface currents in the deep-water ocean region flow from west to east, and there is a cyclonic vortex in the Prydz Bay. The most obvious oceanographic features of the hydrological structure are: (1) Evidence of a well-watered-up over the CDW, with the strongest updip being in the area north of the McLaberson, with the most pronounced depth of 50 to 200 m , Rising warm water separates the winter cold water into two parts, forming an isolated block of warm water. (2) The boundary of the marginal water is obvious, which is the fronts formed around the extremely deep water and the Antarctic cold water. Generally, In sub-surface water, lying roughly between 64 ° ~ 66 ° S; (3) There is a double-catenary structure. During the observation period, the Antarctic bottom water existed in the waters north of Prydz Bay. There may be two sources: one for the local formation and the other for the Weddell Sea and the Ross Sea.
