.irds the south has been used by Michaelis (1923, p. 22) as evidence of 



current, but it may be explained alternatively by the melting and dis- 



ce of the ice carried eastwards across the Atlantic Ocean by the Weddell Sea 



consideration of the water movements in the eastern half of the Atlantic Ocean

 the ' Discovery II' found the pack-ice between April 1932 and March 1933. 



suggests that there are two belts of pack-ice: one between 55 and 65 S carried by the 

 Weddell Sea current and another fringing the Antarctic Continent carried by the 

 current towards the west. In the western part of the Indian Ocean the former ice- 

 stream may have melted, leaving only the continental ice-fringe. It is just possible that 

 even in winter there may be open water between the two ice-streams in the eastern part 

 of the Atlantic Ocean.
