| 摘 要： | 本文利用中国第19次南极科学考察普里兹湾内埃默里冰架前缘水域观测的LADCP、 CTD资料,研究并分析了普里兹湾内埃默里冰架前缘水域水的温、盐特性和海流结构。资料显示,在冰架前缘的水域中存在着四种典型的夏季水团;流速分布显示出东进西出的特征。此外在普里兹湾内的上层和中层海洋中还存在着逆时针和顺时针方向的涡旋:逆时针涡旋西侧是普里兹湾向冰架入流的位置所在;入流的源地是普里兹湾东侧的沿岸西向流。这些特征涉及到夏季普里兹湾内的环流形式、冰架底部的消融速率和冰架水的生成规模以及冰架区域与冰架外普里兹湾内的水交换形式。 |

| Abstract: | Hydrological character and sea-current profiles structure are studied and analyzed in seaarea of the front of Amery Ice Shelf, Prydz Bay with LADCP, CTD data. These LADCP, CTD data were acquired during the 19th Chinese Antarctic Scientific Expedition. Results of this study agree with that, there exist four different kinds of water masses in the area of the front of Amery Ice Shelf in the summer of Antarctica. Current distribution presents a semi-circumfluence which flows in at the east and flows out. Moreover, clockwise and anti-clockwise vortices were found in upper layer and mid-layer in the Prydz Bay. Western areas of these anti-clockwise vortices are positions of inflows from Prydz Bay to Amery Ice Shelf. The source of these inflows is the coastal westward current originated in the east of Prydz Bay. All these characteristics come down to the pattern of circumfluence, ice melt rate under Ice Shelf, scale of Ice Shelf water production and form of water exchanges between area of Ice Shelf and area of Prydz Bay. |
| Keywords: | Prydz Bay Amery Ice Shelf ice-shelf water |
