It is true that the deep water also moves south and ascends in high southerly latitudes, but traces of the Atlantic deep water are not found in the South Georgia region but much farther to the east, since the easterly flow of the water is considerable.

In the Bouvet region the admixture of water from lower latitudes leads to an increase of the sahnity within the intermediate return current. The conceptions of Merz and Wiist have been accepted by biologists who have studied the conditions in Antarctic waters. Ruud (1932), for instance, states that the oxygen of the relatively warm and saline layer is low, and says that " these water masses were last in contact with the atmosphere somewhere north of the Sargasso Sea, so a very long time has elapsed since they were aerated". He says, furthermore, "that the surface layer (of
