. Fig. 15. A continuous record of the surface temperature between 35 and 460 S. on a passage from Cape Town to Bouvet Island, October 1930. and a region of mixed water in between. There is also an outlying stream of subtropical water at St. 450. Such outlying streams sometimes have a depth of 300-400 m., as at St. 450, but frequently they are confined to a shallow surface stratum of only about 80 m., as at St. 431 (ibid.) and St. 1165 (section 7, Plates X-XII). The deeper currents are probably relatively stable features and are likely to be united to the main body of subtropical water farther

The deeper currents are probably relatively stable features and are likely to be united to the main body of subtropical water farther north, but the shallow streams may be only short-lived and isolated. South-east of the Cape of Good Hope the convergence is crossed by section 8 (Plates XIII-XV) in 430 50' S, 250 40' E; the temperature falls from 15-5 to io° C, and the salinity from 35-2 to 34-6 °/00 in about 9 miles. A similar drop of temperature was observed by Brennecke (1909, p. in) between 410 35' S, 220 10' E, and 420 42' S,
