| 摘 要： | 利用第29次南极科考期间在普里兹湾海区释放的8个Argos漂流浮标所获的总计662 d的数据,对普里兹湾及其邻近海域的表层海流特征进行了分析,并和以前的研究结果进行对比,结果表明:普里兹湾西部和北部表层海流基本呈现向西的流动,说明此地区的表层海流以沿南极大陆的逆时针沿岸流为主。普里兹湾东部海流呈现先向南再向西或先向南再向北的流动,普里兹湾西北部海流呈现向南的流动。8个浮标平均流速在0.02—0.20 m·s~(-1)之间,最大流速为1.57 m·s~(-1),流速1.0 m·s~(-1)的大流速区主要集中在普里兹湾、克洛斯角外侧、达恩利角外侧海域,流速1.5 m·s~(-1)的大流速区只出现在普里兹湾、克洛斯角外侧两处海域。

| Abstract: | Based on data obtained during the 29th Antarctic expedition from 8 Argos drifting buoys near Prydz Bay, this study analyzed the surface current features of the sea and compared them with previous findings. The results revealed a surface current flowing westward in western and northern parts of Prydz Bay, showing that in this region, the surface current was a counterclockwise flow along the coast of Antarctica. In eastern parts, the current direction was first south and then west or north, and in the northwest, the current direction was south. The average velocity of the 8 buoys was 0.02–0.20 m·s?1 and the maximum velocity was 1.57 m·s?1. Areas with velocity >1.0 m·s?1 were concentrated in Prydz Bay and beyond Cape Klose and Cape Darnley. Areas with velocity >1.5 m·s?1 were found only in Prydz Bay and the outer region of Cape Klose. |
