Distribution of salinity (%„) between 700 S. and 350 S. in the region of the Greenwich Meridian, March-April 1937. (a) Antarctic Intermediate Water has been shown by Deacon (1933) to reach a depth of about 1100 m. in latitude 450 S. increasing to 2000 m. in 300 S. and decreasing again to about 1200 m. in 50 S. along the meridian of 300 W. It is characterized by its low salinity, which at the level of minimum salinity increases from 34-15 to 34-65 %0 between 470 S. and the Equator; the temperature increase over this distance is from 3-2° to 4-85° C. The principal direction of movement of Antarctic Intermediate Water can be seen in the tem- perature sections (Text-figs. 15, 17,19, 21), in the sinking of Antarctic Surface Water at the Antarctic Convergence, where the isotherms for 20 and 30 C. between 150 and 500 m. swing markedly north. The depth of the layer has been estimated from these sections, at stations where samples were collected near the boundary between it and the Warm Deep Water.
