Discovery (Ship); Scientific expeditions; Ocean; Antarctica; Falkland Islands. 176 DISCOVERY REPORTS in the eastern South Atlantic there seems to be a tendency to an eastward movement, particularly in the Gulf of Guinea, where it apparently diverges cyclonically from the main northerly trend. Thus in the South-west African region the flow is again ill defined. In the subtropical region between the surface-waters, and the salinity minimum of the antarctic intermediate water the T-S curves follow a nearly straight line relationship to within about 200 m. of the surface, above which the circulation becomes more complex within the tropical and sub- tropical surface and subsurface layers. This water mass, represented by the nearly straight line part of the curve, has been termed the 'South Atlantic central water' (Sverdrup, Johnson and Fleming, 1946). The process of its formation is still rather obscure. Sverdrup et al. (1946) suggest that it is probably formed by a simple process of sinking along surfaces of equal density in the region of the subtropical convergence, as the vertical T-S relationship of the South Atlantic 15- 10' 67, /'4O01 ^ (ISO)/0 ^.
