Distribution of salinity (0) between 6o° S. and 40° S. in the region of the Greenwich Meridian, August 1938. The Bellingshausen Sea Current is slightly warmer than the Weddell Drift; consequently, where these two currents meet, the colder Weddell water sinks below the lighter Bellingshausen water. The resulting convergence is normally marked by a mean temperature difference in the top 100 m. of i° to 1-5° C. In Text-figs. \a and \b (p. 167) the position of this boundary is shown for stations made about the Greenwich Meridian; details are given in Table 12 for the stations in the hydro- logical sections (Text-figs. 15, 17, 19, 21). The two types of water can be traced across the Scotia Sea, around South Georgia, and as far east as the longitude of Bouvet Island (Deacon, 1937, p. 25). The main direction of movement of the Antarctic Surface Water is north-eastward across the South Atlantic Ocean, with an occasional swing to north or south. To the west of South Georgia there is
