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.

Key words: Antarctica, Prydz Bay, surface current velocity, large flow area
